HOW TO FIX AN EPC PROBLEM - CONTINUED

HOW TO FIX AN EPC PROBLEM, - CONTINUED

The final note on the preceding blog installment ended on 'scan for Diagnostic Trouble  Codes with a scan tool'. However before we start scanning it is important to note, that Vehicles from year 2000 are fitted with an EPC (Electronic Power Control) system, hence this exposée only applies to cars fitted with a obdii 16 pin female connector, identifiable by its  normally purple core, roughly the same purple of the 6-pin mini-DIN connector  of a personal computer keyboard.  This EPC system / Drive-by-Wire circuit (implying no throttle cable) is also known as the torque circuit. The EPC system controls the EPC light  which turns on if and when there is the slightest malfunction  in the Drive-by-Wire circuit. Any such fault will more than likely generate a DTC (fault code) in the ECM, which is stored in its non-volatile memory, meaning even if the battery is disconnected afterwards the DTC (fault codes) will persist. However, also note that when the battery is disconnected all driver learnt values particular to your driving style, will be erased. Disconnecting the battery may require resetting the convenience electronics, such as alarm, interior lights and the radio. So, most importantly if you don't have the radio code, practice caution because the radio will permanently lock-up hence it's a good idea to use a jumper battery or perhaps even a battery charger to maintain battery power whilst replacing a battery. Or get the code from your service center.

Whilst any problem in the torque circuit is  normally responsible for turning on the EPC light,  the EPC light may also turn on for some other non-emission related engine faults.  When a combination of emission-related and EPC-related fault is encountered, both the MIL and EPC lights may turn on. This alone give one a good idea of whether or not the engine problem is purely torque related or part of an emission-relate issue.

Most pure torque circuit EPC faults are accompanied by Limp-Home Mode which revolve around the basic settings for the Electronic Throttle Control Valve Adjuster, Idling Control, EPC Adaptation and the  Accelerator Pedal Position Senders. Their values are stored in the ECU normally from group 60 - group 62 of the Bosch ME 7 and newer ECUs, however the actual group may vary subject to make, model and engine capacity of the vehicle. For example. Jetta, Polo, Audi TT, etc, EPC adaptation exists at group 060 - group 062, whereas these values may be stored in group 098 for some VW Passat and Audi A4, S4, B5.

Group=060, Adaptation Epc-system
Group=061, Epc-system (1)
Group=062, Epc-system (2)


Emergency Running or Limp-Home Mode

Both Bosch Motronic and Siemens Simos ECU have two emergency running modes to compensate for accelerator pedal sender failure. The first mode triggers when the primary sender G79 (Sender -1) accelerator pedal sender fails, and the second mode triggers when both G79 and G185 (Sender -2- redundant sender) accelerator pedal senders fail. In the first case with one accelerator pedal sender failing, the accelerator position is limited to a predefined value (limp mode) idling speed while some comfort functions will be disabled,  the Air Conditioner for example. By which time EPC light would have already illuminated. However, when the second emergency mode triggers the engine runs only at idle speed. It would be exactly like disconnecting / removing the accelerator pedal completely. On the occasion that I replaced my accelerator pedal, I started the engine and to my surprise it started perfectly normal and idled at a normal rev. So the conclusion is when both accelerator pedal senders / potentiometer fail, it gives you the same, exact, identical symptoms of a physical steel accelerator cable that snapped. Considering a throttle cable is the single most important part of the throttle system in a car engine. So when it breaks the car will idle, but will not rev. The EPC system mimics the pysical cable exactly or as near as dammit.


Siemens Simos ECU J361 with pin connections
Looking at the diagram for accelerator pedal senders G79 and G185, pins 50 and 19 are inputs from their respective highside driver 5V supplies with pins 18 and 45 of the ECU microprocessor are their independent internal earth connections. The two variable voltages at pins 51 and 64 are the inverse of on another. Essentially G185 (secondary) is working as a backup to G79 (primary). Inputs at pins 51 and 64 are constantly monitored by the ECU microprocessor could range from sporadic to too high or too low, to intermittent to absolutely not there. The  ECU microprocessor with its built-in Watchdog Supervision Safety Logic monitoring performing plausability checks for voltage regulation, Over/Under voltage levels, intermittent voltage levels. If for any reason that the calculations based on its internal algorithms do not correspond to its internally stored and expected values either the watchdog processor or the  Main Processing Element enable   a secondary shutdown path to all equipment under its control. In a nutshell, limp mode.

Constant movement of the gold plated contacts on the potentiometer slider eventually wears through and becomes intermittent especially if the vehicle has attained a high millage, considering  how may times the accelerator pedal has been stepped-on and released. It can be roughly compared to a volume control that's gone scratchy from constant use, when it finally worked through its carbon track and makes intermittent contact.  I've known physical  steel throttle cable to last a lot longer than its electronic counter part but they do have a tendency to fray and get stuck inside its sleeve especially when going at high speed, which is kinda dangerous -even life threatening.  With the EPC system this will not happen, rather if the "electronic steel threads fray" the microprocessor shuts the system down by switching over to its stored alternative values.

Looking at the diagram for G188 and G187 it can clearly be seen that they share a common 5v supply (pin 91) and a common earth (pin97) with the outputs from pins 90 and 92 acting as inputs to the ECU microprocessor that control for the throttle valve actuator motor. These inputs are also constantly monitored by the ECU main Processor and its companion watchdog processor. Noting once again that G188 and G187 act as angle sensors much like that of the accelerator position senders. The concept and principal is exactly the same as that for the accelerator potentiometers. When any discrepancy is detected, a shutdown path is enabled which presents itself to the motorist as a car that won't rev. Then there is G61, the knock sensor. Any  knock higher or vibration outside of that expected by the ECU on pin 102 will also enable a shutdown path and sequence limp mode.

Based on this, the inputs and outputs from these three components are vital to the correct functioning of any Drive-by-Wire vehicle. So when a fault occurs and guided by error codes, it is important to ensure that there is wired continuity between these components and the ECU connector. Wiring harnesses are subjected to a fair amount of shaking and can break inside of the PVC sleeving. Especially sensitive is the 6 pin Electronic Accelerator Pedal Plug Connector Wiring Harness for VW Polo, Golf, Audi, Skoda, Fabia. VW part number - 3B0 972 706. This replacement part needs to be soldered onto the  wiring harness after cutting off the original plug.

HOW TO FIX AN EPC PROBLEM

HOW TO FIX AN EPC PROBLEM

Electronics have taken the motor industry by storm, so-much-so, that electronic black boxes and discrete components have come to replace several mechanical systems. Case in point, Drive-by-Wire system, where a mechanical cable is replaced by an EPC (Electronic Power Control) system. Or a shared coil or carburetor is replaced by a set of individual electronically controlled coils or electronically controlled injectors, respectively . As a result, providing us with increased safety features, tighter and better engine control, additional creature comforts, convenience and so much more. 

Virtually every system in the modern day car is digitally controlled by a some Electronic control Unit (ECU) or a bank of dedicated on-board computers  distributed throughout the car, all of them networked to a Central Bus System. There are numerous bus systems used in electronics but CAN bus developed by Robert Bosch in 1986, has quickly gained acceptance into the automotive and aerospace industries. With the continued development of more complex ECU applications,  much larger quantities of data needed to be  processed, scores of more signals needed to be measured, and a growing number of other parameters needed to be optimized. 

CAN bus was the answer to surmount these problems though it is essentially a serial bus protocol used to inter connect individual sub systems and sensors as an alternative to conventional multi-wire looms. In a nutshell, cars have gone electronic processors, is firmware based, software driven and data analysed, artificially semi-intelligent and electronically complex.  All of a sudden automotive mechanics needed to learn loads of new words like microprocessor, microcontroller, quantitative analysis, electronic engine-management systems, potentiometers, sensors, signal processing, frequency response, memory-mapped  let alone how their individual functions. 

To add insult to injury, abbreviations like Controller Area Network (CAN), CPU (central processing Unit), RAM (Random Access Memory), EPROM (Electronically Programmed Read Only Memory), LAN  (Local Area Network), ADC (Analogue to Digital Converter), distributorless ignition system (DIS), etc, just flooded the motor vehicle repair market. 

Talking about abbreviations, EPC, is the official abbreviation for Electronic Power Control when referring to the Drive-by-Wire Torque circuit,  though it also stands for Electronic Pressure Control when referring to the Automatic Transmission.  When the Torque control EPC circuit fails for whatsoever reason, the  EPC Warning Light (K132) located in the instrument cluster lights up, which then could cause the car to enter into "limp mode", depending on the severity of the problem. Limp mode is a protective state that the car's ECU enters into when it recognizes that there is a problem with it's logic program. 

For example, when an expected signal value originating from a sensor varies significantly from the predetermined program  specification, the ECU then enters into a secondary/ emergency programme in order to protect the engine / transmission from damage. The ECU is constantly expecting a regular stream of signal values from various sensors, like for example the Throttle Position Sensor, or the Mass air Flow Sensor, or the Engine Speed Sensor, or the temperature sensor, etc. As long as these signals stay within specified parameters for certain operating conditions, the ECU performs faultlessly at controlling the engine. 

Due to  the rapid expansion of electronics in motor vehicles, automotive mechanics in general were over whelmed by the introduction of this new evolution in technology and as a consequence didn't stay abreast of automotive electronics, thus now seem to have great difficulty in solving electronic problems on client's cars. Replacing parts indiscriminately with the hope that they get lucky and that the actual faulty component is among the suspected parts that were replaced.  

Many, many, many VW, Audi, Skoda, and Seat owners can testify to this, since most have first hand experience of taking their vehicles into the service agent, only to get the car back after having to foot an enormous bill for replacement parts that probably weren't faulty in the first place, only to discover later that the problem the car was taken-in for, still persists.  EPC problems essentially have most VW "mechaicians" by the short and curlys.  But an EPC problem is not that difficult to eliminate if checked systematically instead of trying to trace it by replacing components by substitution.

DESCRIPTION OF HOW THE EPC WORKS

When the ignition is initially switched on, the Motronic Engine Control Module (ECM) performs a quick self diagnosis of all components that are important for the correct functioning of the Electronic Power Control. If all components pass the  diagnostic test the EPC light goes out. However, should  the Electronic Power Control (EPC) Warning Light not light-up when ignition is switched on, or if a  malfunction  is detected in Electronic Power Control system whilst the engine is idling, the Motronic Engine Control Module (ECM) will turn on the Electronic Power Control (EPC) Warning Light, sort of constantly.  When this happens, a DTC entry is made in the Motronic Engine Control Module, then its time to scan for Diagnostic Trouble  Codes with a scan tool.

NB! 

EPC also stands Electronic Power Control but also stands for  Efficient Power Conversion (EPC), Emergency Power Cut (EPC), Error Protection Code  (EPC), Event Process Controller (EPC), Embedded Personal Computer (EPC), Embedded Programe Controller (EPC), Erasable Programmable Chip,  Electronic Page Composition (EPC), Editorial Processing Center (EPC), Electronic Publishing Center (EPC), Energy Performance Certificate (EPC), Engineering, Procurement and Construction (EPC), Earnings per Click (EPC), Electronic Pressure Control (EPC), Electronic Product Code  (EPC), Enterprise Planning and Control (EPC), Every Penny Counts (EPC), Earth Population Control (EPC), Enhanced Power Control (EPC),

VW BREAKDOWNS

VW BREAKDOWNS

Virtually everyday I see at least a half a dozen of brand new cars hitching a lift to some service center. Rollsbacks are becoming pervasive and are thus trending because the days when you could manage a quick repair along the roadside is long gone. Whether you drive an older well used or brand new vehicle, breakdowns are inevitably and will happen at the most inopportune moments or at the worst possible time. Having a roadside assistance service like the AA (Automobile Association) can provide some peace of mind, especially to female drivers with infants or aging parents / grandparents on board. Somehow breakdowns seem to happen when you are smartly dressed enroute to a function of sorts or when you are late for an appointment. That's Murphy's Law for you.


VW Golf GTI with a engine sensor issue

VW Golf GTI going nowhere slowly
The most common road side problem today seems to be  cars running out of fuel, because of erroneous assumptions. Due to the recent rapid rise in fuel prices everyone is still topping up their fuel tanks based on note value rather than on litre value.  For example, R100.00 worth of fuel (8.2 litres) is not the same as asking for 20 litres of LPR fuel (R250.00). Hence drivers are judging driving distance based on the Rand value, often ignoring the fuel guage and getting stuck without fuel as a consequence, though expecting the rand value of the fuel they bought should have taken them a lot further than it actually did. 

A dead battery is another common issue, which is most susceptible in winter, especially relevant to delivery vehicles that drive short distances, starting their engine often, thus not giving the battery sufficient opportunity to charge fully. Persistent battery problems are more often than not caused by a faulty alternator regulator and is not normally repairable at the road side. I've had my alternator die on me at night while driving home from movies, and I was actually watching my headlights getting dimmer by the meter, as I drove. Fortunately I made it home before my battery ran down completely.

Then there is the clutch cable that snaps under stress,  which is normally a deal breaker because it inhibits changing gears. Once when this happened to me, I started my car whilest the transmission was in 3rd gear causing the car to lunge forward as the starter rotates. It's kinda like using the starter to propel the car forward until it starts. When my car's engine started, I managed to drive all the way home in third gear without incident.

VW Polo with a ESP and EPC issue

VW Polo enroute service centre.
A flat tyre / blowout is another roadside issue, especially if you discover the spare tyre deflated due to the duration of time it spent in the boot without being checked. The worst thing ever is not being able to loosen a wheel nut that's been air torqued by the last tyre repair place you visited. 

An overheating engine can just stress you out because the first thing that comes to mind is the possible cost of repair. An overheated engine is commonly caused by a snapped fan belt or stuck thermostat which can cause the cylinder hear gasket to blow if not detected and repaired in time. When my car's engine overheated, I was some 30 Km out of Bloemfontein on the N1, enroute Cape Town; somehow the attendant at the filling station who topped up my radiator water level didn't replace its cap.  As a consequence the
water bubbled out and with insufficient water to keep the engine cool,  the  head gasket blew and I had to stay in Bloem for 13 days. It was an expensive exercise, the cost of a deco set with head gasket, the cost of the opportunistic mechanic, and the cost of hotel accommodation and obviously food.

A not so common roadside fault is locking your keys inside the vehicle or even loosing your keys. Remember the microchip inside your key can also go faulty and is the only thing that can disable your immobilizer. If this should happen it would be worthwhile having roadside assistance because they generally have a relationship with vehicle manufactureres and authorised dealers and have access to Key Assist. 

Regular services would do your driving spirit the world of good because any worm components can be detected before they actually go faulty. On of the worst roadside breakdowns is a snapped cam belt but if checked at regular services and replaced before it breaks would save you a shed load of money. It is worthwhile keeping  a set of jumper leads and a 5L can of water in you boot as well as an empy 5L can and a funnel, just in case you run out of fuel.  A spare fan belt and a mechanical toolkit would also be beneficial as boot luggage. Get into the habit of continually looking at your instrument cluster while driving to check your guages for normality, especially oil pressure, oil level and water. Check your coolant level yourself if possible before going on any long trip, and please don't allow garage attendants check it, at least not without your supervision.  Also make sure your have a spare key. 


I've never seen two VW towed in tandem like the two Toyotas above.

Two police vehicles that needs some TLC

Looking at the two images above is a least a consolation to Volkswagen owners that it's not only VW  vehicles that seems to enjoy riding on the back of rollbacks.

VAG RELAY INDETIFICATION

VW RELAY PROBLEM, AUDI RELAY ISSUES, SEAT RELAY TROUBLE AND SKODA RELAY DIFFICULTIES.

So, you have an electrical problem with one of your car's relays and you have no idea which one is troublesome or misbehaving because even the Bentley manual got that information wrong. Well, your'e in for a treat because I have listed several VAG relays in their "marking number order", making them easy to identify. For example, the manual lists the Motronic Engine Control Module Relay as item (J271) which is in fact Relay #428 for older gasoline powered VW, AUDI, SKODA and SEAT cars and Relay #460 for later (newer) gasoline powered VW, AUDI, SKODA and SEAT cars whereas  Relay #109 is the Motronic Engine Control Module Relay for older diesel powered VW, AUDI, SKODA and SEAT cars and Relay #120 for later (newer) diesel VW, AUDI, SKODA and SEAT cars. VAG cars have relays strew all over the car, sometimes in the engine compartment, sometimes under the dashboard, sometimes in the fuse distributor, etc, so they're not always that simple to find. However if you know what they do, then fault finding relay issues / problem,  becomes simple.


Relays with their VAG numbers inscribed on the plastic housing.


















WHAT IS A RELAY?

Technically, a  relay is just a remote switch. Most of the VAG relays are 4 pronged, and the reason relays are use as remotes switches, is because its contacts can carry a lot more current than a dashboard mounted switch. Besides relays make it convenient to switch several sets of contacts simultaneously when the solenoid in energized. Relays come in all sorts of configurations among which are single pole single throw, double pole double throw, etc and can be really toublesome. Most VAG solenoids have 4 prongs, 1 or 2 regular prongs used for the solenoid winding and 2 or 3 heavy duty prongs allocated for the switch contacts that carry higher currents. Relay contacts can become intermittent after suffering consistent contact bounce. The relay solenoid can even burn out, causing the relay not to respond. The most common problem on relays is cracked or dry solder joints on the printed circuit board around the heavy duty prongs. I've also found the plastic stays that supports the metal relay contact melt due to heat build-up rendering the mechanical switch movement inoperative.

Cracked / Dry Solder joints. This is what happens inside relays.



It is also common for relay contacts to fuse/melt/weld together either in the normally open or the normally closed position.  A telltale sign is that the plastic housing is discoloured in an area and often bulged due to excessive heat where this happens. Sometimes the relay prongs heat up so much that it melts  the socket it plugs into causing the PVC/plastic to flow between the prong and socket contacts causing an open circuit. Either way, relay will have to be replaced and perhaps even the relay socket.  VW used many Multi purpose relays like Relay #1, Relay #53, Relay #204, Relay #645 to mention but a few. These can easily be used in place of most other relays should it meet the necessary current specifications.  Spade terminals connected to a short lengths of appropriate thickness wire  from each sprong and plugged into the correct relay socket slot can serve as a converter if the switch prongs are differently configured from the one you need.

SEAT CHECK ENGINE LIGHT PROBLEMS

SEAT COMMON PROBLEMS AND SOLUTIONS  

The supermini SEAT Cordoba based on the Seat Ibiza Mk2, has been around since 1993. When the Volkswagen AG took over production from the Spanish auto maker, it was  replaced by the Ibiza ST /  Seat Vario built on the same platform as the Mk4 VW Polo and the Skoda Fabia. They are available in coupe, saloon and estate in 1.2, 1.4,  1.6, 1.8 and 2.0L petrol and 1.9L diesel engines with either a 5-speed manual or 6-speed tiptronic gearbox, and were in production until 2009. These cars  were  renown  for their good performance, handling and its safety features, but like all cars, they tend to develop common problems after a few years. Pero es un buen coche para comenzar en Mexico y España.

The most common of all engine problems was engine misfiring and in the process turning on the Seat check engine light, or the Seat Ibiza engine warning light, or  Seat Altea engine warning light, or the Seat Leon engine warning light, or Seat Arosa engine warning light, or Seat Leon TDI engine warning light, or Seat Cordoba  engine warning light. The most likely cause of this problem was the coil pack or the spark plug leads which needs replacement. A telltale sign was excessive  shaking when idling. This was very prevalent when coming to a stop street or traffic light or when starting first thing in the morning. Unlike cars of yesteryear  that had a single coil and a distributor that supplied a spark to the upcoming spark plug; these cars have its own coil pack for each cylinder. More coils packs  just increased the amount of things that could go wrong, and do they go wrong.


Another common problem with the Mk4 was a lack of power which also turns on the Seat Ibiza engine diagnosis warning light or Seat Cordoba engine warning light.  The cause of the problem in most cases is  the MAF (mass air flow) sensor. A telltale sign is a lack of power at high speeds and or just  poor overall acceleration. It is always worthwhile to try and clean it with compressed air but if this didn't solve the problem, replacement is the only option.  Once repaired,  one would feel an immediate improvement on performance. 






Many Seat Cordoba window wipers also just suddenly stops working which sometimes turned out to be the wiper linkage that seized and sometimes turns out to be the wiper motor and sometimes both. Then there is the ever creaking noise sometimes sounding like an exhaust rattle coming from the front suspension when driving over speed bumps or rough surfaces. This turned out to be the anti roll bar bushes which after replacement solved the problem. A problem that plagued the automatic models is the ever noticeable red oil mark on the ground underneath the car. The origin of the leak is either gearbox seal leaking or the selector shaft seal that is leaking. Seal replacement normally stops the leak. Failure to address this problem ends up with the gear lever stuck in park with the PRDN light glowing right red on the dashboard. The gearbox  grinds when attempting to put the car into drive but will kick in with an huge thud.

Then there is the breaking distance problem on certain models (Ibiza, Toledo, Cordoba, Leon, Vario and Inca) fitted with ABS, needing a lot more force to be applied to the brake pedal to get the car to stop. The cause of the problem turned out to be tension cracks that develop in the vacuum pipe going to the brake servo near to the connections area. This is in fact a manufacturing fault that can be replaced under recall free of charge. After replacement of the vacuum pipes breaking was back to normal.

Ibiza, Altea Toledo, Leon Toloedo, Cordoba  and Alhambra vehicles fitted with a 3 and 4 cylinder pump injector engine with 2 valves per injector is prone to the bolts on the tandem pump cover that breaking off.  This was also a manufacturer  fault and vehicles were recalled to have the pump checked that was supplied by a certain manufacture.

Seat Ibiza and Seat Toledo and Seat Leon with VINs ranging from VSSZZZ1MZ1B036908 to VSSZZZ1Mz1B044227 seem to have a problem with head airbag unit which would fail to activate under certain collision conditions. Seat Altes,Toledo and Leon with 2 L TDI engine and  6 speed manual VIN ranging from VSSZZZ5PZ4R000048 to VSSZZZ5PZ4R017390 and VSSZZZ5PZ5R000026 to VSSZZZ5PZ5R103620 and VSSZZZ5PZ6R000009 to VSSZZZ5PZ6R001638  have flywheel problems that was also recalled for replacement.

The Seat Cordoba 1.9 TDI also developed starting problem when not driven for a day or two. But will eventually start after several attempts, idling very rough and smoking. In some cases it just drained the battery as well. But once she started it will start every time thereafter until left to stand for a day or two again.  This was caused by the diesel pipes sucking in air causing the diesel to flow pack towards the tank. The cause was a leaking diesel filter. A very annoying problem with some Mk4 is the drafts that comes in through door seals. It seemed that these rubber seals tend to collapsed after 5 years. Another thing is the coolant sensors / temperature sensors are generally of a very poor quality on all VW/Audi/Seat/Skoda group cars. They just tend to go faulty all the time. Surprisingly most of these problems are also prevalent in VW Polo range, after all SEAT is just another Mk4 VW Polo that has been badge engineered.

IMMOBILIZER

VW, AUDI, SKODA & SEAT IMMOBILIZER PROBLEMS

The worst thing that can ever happen to you especially when you're in a hurry to get to an appointment on time,  is to turn-on your car's ignition key and see a yellow immobilizer symbol (car with a key below it) flashing in your instrument cluster accompanied by a fairly loud ear piecing audible signal. When you witness this, your car isn't going to go anywhere and neither are you. I suppose there are worst scenarios you could be in like when you stop along a dark and lonely road at night, compelled to take a pee, only to return to your car, to be met by the yellow flashing immobilizer symbol. There are so many VAG Vehicle owners who have experienced some sort of immobilizer problem with their cars and those drivers who haven't, I'm so sorry to say, but its only a matter of time before you do. That sounds very pessimistic, but once again, I'm sorry to say but that's the reality of the situation. It is what it is.


The dreaded Immobilizer symbol

Looking through my database of immobilizer issues, some of which I have shared with you below, gives you a fair idea of what can be expected from your VAG vehicle in the future. VW, Seat, Skoda and Audi vehicles comes out with a various versions of theft deterrent software systems, starting with vehicles without an Immobilizer (Pre 1995),   to Immobilizer I (Immo I - 1996), to Immobilizer II (Immo II - 2002+), to Immobilizer III (Immo III) aka Transponder III, to Immobilizer IV (Immo IV) and  the 5th generation Immobilizer (Immo V - 2011). There are also various Immobilizer hardware integrated into the instrument cluster, two of which are (J285 & J334 Immobilizer Control Module) and  (J285 & J362 Immobilizer Control Module).  Not to state the obvious, VAG cars are equipped with Anti-Theft Engine Disable immobilizers to circumvent theft; and should a car thief swap-out an ECU without matching it to instrument cluster, the engine will start briefly then die and this will be repeated indefinitely. 


AUDI, SEAT, SKODA and VW AVITARS



Since the implementation of Immo 3, variable code evaluation is use in both  the engine control unit and Immobilizer control unit. They use an equation / algorithm that calculates the generated variable code that both control units must agree upon. So, if you ever start your car and it stalls after about 1 second, then its perfectly safe to suspect the Immobilizer as faulty whether it displays the immobilizer symbol or not.  In such a case  the DTC memory should be checked and, if necessary, the control module adapted. Whether or not the has Immobilizer disabled the ECU can be verified under address word 17, and or address word 25, using a scan tool like VCDS, ODIS,  Launch, Autoboss,  Autel MaxiDAS, etc. The data whether  ON or OFF, sits in measuring block 007 under Central locking. Most importantly the DTC are the clues that's going to point you in the right direction.


ODIS is the latest VW, AUDI SEAT SKODA, BENTLEY,
LAMBORGINI and PORSCHE Diagnostic Software.




So, when the ignition is switched ON, the Instrument cluster / Immobilizer Control Module enables or disables specific vehicle functions based on a hand shake. What this means is that when the switchblade key is pushed into the ignition lock, or placed in proximity of the  coil transmitted radio signal, the instrument cluster electronics detects the key and initiates a data transfer between the pickup coil in the steering column or ignition switch and the RFID (Radio Frequency Identification) capsule embedded in the fob key. If the correct / unique identification number / authorized security data stream is received at the Immobilizer Control Module it permits the engine to start and idle uninhibited. But if it doesn't the car wont start.
RFID capsules are tiny, it stores data unique to your car  and can be found inside your fob key.


The list below constitutes just a smatter of immobilizer errors that VAG car owners can experience, which range from a low fob key battery, to an instrument cluster or ECU replacement. And somewhere in between you will have, wiring harness issues ranging from intermittent to open circuit and even short circuit. Active RFID tags have their own power source whereas passive RFID tags used in all fob keys don't require power. 
Essentially they consist of a scanning antenna, a  transceiver with a decoder to interpret the data and  a transponder - the RFID tag - that has been pre-programmed with the relevant information specific to your VIN, ECU and Instrument cluster. A dry joint on the pickup coil inside the capsule can prevent the necessary hand shake thus its a good idea to have a second matched fob key available if the key that won't start the car is suspect. In the list below, you also find appropriate codings for  Immobilizer Module address 25 and as  can be clearly seen, different control modules have different ODX/ASAM datasets, different software versions and different .rod files. Before changing any codes, make certain that you have a printed copy of all existing codes.
