VW POLO 9N MODULE CODING

VW POLO 9N MODULE CODES

It has become an accepted fact that VCDS and other auto diagnostic software determine the electronic modules built into each car, both make and model by its engine type. It then matches a library file for the that engine with the appropriate common settings and coding for said engine, if and only if there is a library file for that model.  However this may not be entirely true because various of these electronic modules are controlled by varying versions of software and the likelihood is that identical cars could have the same electronic modules but with different software which implies that the module in question has a different coding. This is very evident in the VW 9N range of cars, as can be seen from the data below. VW 9n specifically sport the  following AMF, ATD, AWY, AZQ,   BBX,  BBY, BKY, BMD, BMS, BMT,  BNM, and BNV type engines ranging from 1.2l to 2.0l. The software version used with each of these engines can be determined by the letter suffixed to each control module number. For example,  an electronic module controlling the brake system 6Q0 907 379 L for instance has different software 6Q0 907 379 Q which also has different software from 6Q0 907 379 AS. Since their numbers appear the same is normally expected that they are interchangeable, but this not in this case. Electronic module 6Q0 907 379 AS controls hardware ESP 8.0 front has software H05 0003 and a coding of 0002371, electronic module 6Q0 907 379 Q controls hardware ESP 5.7 front with software H03 0000 and a coding of 0003362 and 6Q0 907 379 L controls hardware ABS FRONT MK60 0101 with a software coding of 0001097. Since different models of the same car are fitted with different onboard comforts and control it is more than obvious that the same electronic module with identical software will be used.

AUDI EPC LIGHT

AUDI HAS LOOMINITUS

Audi TT, A4 1.8T, A4 B5 1.8 Auto, 2.5 V6 Quattro B6, 1.6L A4 SE, 1.8L R4, Audi 8T0, Audi A6 C5,

Does your Audi occasionally have a hard time starting, yet finally starts just before you give up?  So when it starts, the EPC and ESP lights are on, then the engine cuts out. You restart and she idles rough and the check engine light comes on? After a while the EPC and ESP light go out, thereafter the car drives normal until the next time this happens. 

Or, as you are driving in manual mode, you noticed the ABS and ESP lights come on and suddenly your Audi's engine loses  power and goes into limp mode. You switch off, then restart, it idles rough but won't rev over 1500 RPM and she sounds like a tractor. You switch off once again, restart and the tractor is gone. So you get the Audi home driving at a snails pace, the next morning you start her and it seems like there was never any problems because she now idles and drives normally.

Or you are VCDS savvy, encountered an EPC light problem, cleared the fault and the next day it come back on. Several days later the EPC light comes on again, stays on and refuses to switch off. Once again you do a scan and you get a ton of  implausible  and intermittent DTC errors. 

Or your start the Audi, it idles for a few seconds then dies with the EPC light and ESP lights on. You clear the faults, lights go out. You drive the car for less than 3 km and it goes into limp mode. You disconnect the battery and reconnect and it seems fine thereafter. A few days later and the same thing occurs.

The Throttle body plug thats seem to haunt Audi owners.

What you have been experiencing is just a sampling of what the future holds. You Audi is suffering from "loominitus",  its loom is having issues, better known to auto electricians and motor mechanics as wiring harness issues. The culprit in all the above case is the 6 pin plug interfacing with the throttle body. Of late, this throttle body plug has become  quite trouble, you could almost call it common. Don't use contact spray on the plug. Ideally that portion of the loom needs to be replaced but since the female part of the plug is intermittent - hence faults come and go - it's worthwhile just replacing the plug and join the wires using ferrules and double crimp them. Cover the wires with shrink sleeving and avoid insulation tape because the engine heat will melt the PVC which will go sticky within days and  its messy.  

The troublesome Throttle body plug - connect thicker wires as per old plug.

Throttle body replacement plug and colour coded wiring

I am so sorry to say, as the looms in the newer cars age, you should expect worse issues with the wiring harnesses.  See the list of sub loom components for the VW Polo here. Pieces of the harness that makes-up the whole.

Anyway should you scan your ECU, you will most probably find the following faults and perhaps others not listed here. The image below points to the troublesome plug.

WIRING HARNESS ISSUES

AUDI ON A ROLLBACK

As I've mentioned in my previous blog, not only Volkswagen  vehicles but every new vehicle's wiring harnesses have undergone a huge technological evolution since 1984. So much so that  30 years later the average wiring harnesses has become extremely complex because the number of terminals have progressively increased from a typical 200 terminals in a 1994 vehicle to as many as 1,400 terminals, if not more in the very latest models. It therefore stands to reason that with so many terminals or connections, each and everyone of them are subject to corrosion, high resistive contact, poor contact, intermittent and implausible contact  and at times no contact.  The amount of copper wire used in older cars have also decreased substantially, from as much as 4 kilometers in length to about 1 kilometer. That's equates to a 75% saving on the wiring harness.  However with all the new technology and control modules and data buses, the cost of the wiring harness  cost equates to a quarter of the cost of the entire car. 

VW Polo Wiring Harness

As can be see in the image below, another VAG car sucummbed to hi-technology and desperately needs the service centre because it went into "Limp Mode".  It's most likely an electrical fault has caused this but that's just speculation on my part. However, since more than 50% of all warranty repairs are caused by electrical malfunctions, and approximately 30 percent of all tow-ins, are due to problems associated with the wiring harness, it can be therefore be said that 80% of all troubles experienced by car owners today are due to electrical faults.  Can we then also say that these fault are constantly recurring  because the manufacturer has overlooked the fact that 1400 contacts will invariably be influenced by  bumpy roads, shaking and hoping and flexing, subject to moisture and heat and dust and dirt? Desktop computers also have several hundred contacts but the difference between household computers and cars is that computers stay in a fixed place and doesn't get knocked about and shake on bumpy roads nor subjected to extreme heat and cold and moisture. Wouldnt it be fair to say that any car with electrical problems caused by the wiring harness should be repaired by the manufacturer under warranty and if not, these cars should be recalled. Anyway,  here is the Audi scan for your perusal.

Audi on a rollback on the way to the clinic.

So by the looks of it, with so many error codes,  it does seem like the wiring harness could be faulty because the control module lost communications with the Instrument cluster and when this happened the checksum no longer tallied, so the immobilizer inhibited starting. But considering that the key signal was low or intermittent, it could even be that the CR1220 lithium battery in the key fob died hence could not deactivate the immobilizer. It's just so scary that your relatively new and supposedly reliable VAG vehicle could act up at any time on a lonely road and leave your stranded, so make sure you have a tow-inn agent on speed dial.

INTERMITTENT IMPLAUSIBLE

VW POLO 9N HIGHLINE

The VW Polo comes in three flavours viz. the 9N1, 9N2 and the 9N3, dating from 2002-2009.  The Skoda Fabia and the Seat Ibiza/Cordoba share many of the 9N trates but omit Address 25 since all their onboard control module functions are not identical. In the case of the VW Polo, it shares the coding in Address 17 with Address 25 because they are linked, but this applies morso to the 9N3. However, the easiest way to recognised the 9N and its clones, are by the 6Q0, 6Q1, 6L0, 6N0 and 6R0 modules which are also populated in the Polo 6N range. The interesting thing is that even though some module are the same in both its hardware and software, they have different codings specified. 

It is understandable, since the coding value is subject to the collective components fitted because the coding is a sum of the binary value applicable to the individual components. This can be seen in the three scans below. Be that as it may, module coding seems to be a huge problem with most vehicle owners who do their own repairs, however I have also seen qualified mechanicians struggle for days to get a car back to its readiness state. The status chart below is what every VAG driver / owner desires from their vehicle, but  is often totally elusive.

VCDS FAILED READINESS SETTING

What I have found, is that when a component that contributes to the module coding value malfunctions, the scan reads "1 Fault Found: 01044 - Control Module Incorrectly Coded" but if the malfunctioning component is first repaired or replaced, and the fault is cleared, the  01044 code does not return since the checksum of the module is once again correct. Many vehicles owners see this 01044 code and start changing module codes, normally just to see what happens. But, and a big but at that, before I continue, I need to stress that it's imperative to print out a scan of the faults and the module codings before any repairs are attempted, so that, if there is a problem, you can always revert back to the original coding. Failure to so could incapacitate your car until it can be correctly re-coded which could be both time consuming and expensive. Implausible and Intermittent (implausible  intermittent signal) problems on VAG cars are rife or rather intermittent and implausible  (implausible  intermittent signal)  problems on all cars are rife ever since control modules were introduced. The main reason for this is bad, poor or intermittent electrical contact, especially  considering the vast increased in the number of multi-pin plugs and sockets and edge connectors. Because vehicles move,  the  forces on the electrical connections constantly changes and that's besides the expansions caused by heat and the contractions caused by cold, and the corrosive effect of the weather on vehicles. Hence intermittent problems in all languages abound. What follows is just a sampling of the intermittent and implausible (implausible  intermittent signal) error codes we could encounter.

VW JETTA WIRING HARNESS

However,  we all desire the following messages from our cars:-  Aucun code défaut trouvé. No fault code found. Kein(e) Fehlercode(s) gefunden. Nu a gãsit coduri.  The wiring harness of all cars are made with flexible multicore wire with terminal connectors and clip-lock plugs to facilitate connection durability when driving on bumpy roads and uneven surfaces but it seems that shaking, vibration, heat, shafting and corrosion are responsible for the above errors which would probably not resulted if there were not as many interconnected sub harnesses, and multi-pin electrical connections. Volkswagen  vehicles wiring harnesses have undergone a huge technological evolution since 1984. So much so that  30 years later the average wiring harnesses has become extremely complex because the number of terminals have progressively increased from a typical 200 terminals in a 1994 vehicle to as many as 1,400 terminals in the latest models.

The cost implications of these new wiring harnesses and electronic modules constitute more than a quarter of the price of the cars. It is estimated that it takes approximately one and a quarter hours to completely assemble and engine on a production line, whereas it takes more than 5 hours to assemble a wiring harness. Since the complexity of wiring harnesses  escalated exponentially, it is only obvious that the time and cost associated with repairing wiring harness would increase considerably. Thinner wires are used carrying extremely low-level signals and data, interlinked electronic control modules, sensors and actuators communicating in several protocols, collectively resulting in limited access and mass confusion. Restated, automotive repairs have become lot more complicated and it is estimated that almost half of all warranty repairs are caused by electrical malfunctions, and approximately 30 percent of all tow-ins, are due to problems associated with the wiring harness.

This emphatically tells us that the wiring harness is no longer a collection of wires and connectors bound together, because each and every length of wire, connection,  twist and turn, is carefully engineered to suit the application and its environment. Therefore whenever electrical harness repairs become necessary, don't use shortcuts and offcuts pieces of wire from an old extension lead or solid wire from domestic electrical cable and solder joints. Solder joints will eventually break due to vibration and spirited driving. Use the appropriate motor grade multicore flexible wiring of the appropriate diameter with the correct terminals and the appropriate electronic modules and components to restore the wiring harness to its original integrity because failure to do so, will only result in more intermittent and implausible (implausible  intermittent signal) contacts. To give you some idea of the wiring harness complexity I have included the numbers of the various sub harnesses that constitute the entire harness for my car.

01044 - CONTROL MODULE INCORRECTLY CODED

CONTROL MODULE INCORRECTLY CODED

Since 1994 auto repairs has drastically changed, so much so that most cars cannot be repaired  without a diagnostic code tester. It is therefore advantages to invest in one of the hand held free standing devices or cable interfaces that plugs into a USB port of a laptop computer running the appropriate software to do the necessary. The best software to date for Vag cars is undoubtedly VCDS from Ross Tech. Their latest version is version 14. The software is absolutely free but the interface cable comes at a cost. It is a bit pricy but its a worthwhile investment since it entitles you to free updates for life. This interface cable has a built in PAL chip which doubles-up as a dongle containing the cable activation code. Even though there are several out-band 3rd party interface cables available on the market, none of them gives you the confidence that a VCDS HEX-CAN automotive diagnostic device, that is backed by a service company ready to help with any automotive queries, gives you. Bare in mind that this software has the ability to change the behaviour of the electronic control systems built into your car which can result resulting in catastrophic effects if not performed correctly. If you lack the competence or confidence to perform these operations, or even if you are unfamiliar with or the software, I urge you to refrain from changing anything and obtain an experts advice or assistance. Write down or print out all codes and settings so that it is easy to revert back to them.

Below are just a few of the faults that have popped-up on various vag cars over the past few years. Since the codes cover all Vag cars, the code "01044 - Control Module Incorrectly Coded" has occurred several thousand times in all makes and models of Vag cars, in all languages and countries throughout the world.

What I find most intriguing is that for most DTC codes, VW offers some sort of help by using words like "intermittent" " implausible" "short circuit" "limit exceeded", etc.. like these faults below, but the 01044 faulty code featured above offers absolutely none. However, I have included some data below that may be of some help. Should you find these codes helpful, all I ask is for you to like my site on G+1 , Facebook, Twitter, Pinterest, etc.

VW 9N CODES FOR:
CONTROL MODULE INCORRECTLY CODED

If  one of the following controllers is fitted in your car, try each of these codes individually  and you are guaranteed to solve your " Control Module incorrectly coded" problem, providing you have just changes the coding of one module or replaced only one module.  I need to stress as I have in a previous blog that every Control module that is fitted in your car has a prefered coding which is subject to the equipment it supervises. As such, its coding is stored as an onboard binary number, which in essence is the binary sum of the features for that specific module. Whereas the master ECU / Ctrl Head Dash  also stores an onboard binary number which in essence is the binary sum of all the Control Module's coding fitted in the car. This binary sum is called the checksum and any incorrectly coded  module will result in an erroneous checksum. If this is the case, the erroneous checksum is compared to a reference checksum also stored in the ECU module and any discrepancy could incapacitate your Volkswagen completely or present you with some peculiarities and error codes to match. Like the notorious 01044 control module incorrectly coded error. Checksum verification was adopted by BOSCH Motronic ECUs to validate its EPROM's stored data. So, it is wise not to change the coding or replace any control modules in your VW AUDI, SKODA or SEAT unless you are au fait with binary and hexadecimal number systems.

A couple of weeks ago to my surprise,  I discovered that my car's front tyres were running  smooth on the inside.  It was that bad that I needed to replace them but somehow I never noticed until from a distance, I saw something white stuck to the right side front tyres. I was thinking it may be a sticky sweet wrapper that got stuck to the thread, so I went to remove it. That’s when I saw it was a patch of shining wire protruding through the rubber. I was dismayed. The outer edge up to the middle of the tyre had perfect thread, at least 4mm or more but the inside was bald as an egg.

Thats where the control arm rubbers sits, 

There was no way I was going to fit brand new tyres and allow the same to happen to them. I suspected that the alignment went awry so I drove my car in that condition to determine whether I was right or wrong. I released the steering on a straight road a few times and every time the car veered to the left, towards the pavement. Convinced that it was alignment, I fitted my spare wheel and took my VW Polo Highline for wheel alignment to get it sorted before replacing the tyres.

 After waiting for more than an hour at the wheel alignment centre, it was eventually my turn to get service. My car was hoisted about hip high on the lift. The technicians then jacked-up the front wheels placed metal pad of sorts under each of the front wheels which was part of the wheel alignment sensor equipment that they later fitted to all four wheels. They then centred the steering wheel, locked it in place with a mechanical device and fired up the diagnostic computer/programme to check my car's wheel alignment. A good 15 minutes later they discovered that their version of the diagnostic software did not have the settings for a VW Polo 2.0 litre Highline. In fact there wasn't even a 2.0 litre Polo category listed.

The technician scrolled through the entire list a couple of times before he gave up and told me that they are stuck without the correct setting and therefore cannot do the alignment. I asked, what about trying the software for one of the other VW Polo models. Considering all the Polo's are the same shape and size and that it’s only the engine capacity that vary, perhaps it may work.  So he tried the 1.8 litre setting which showed my Polo's alignment was perfect and that there was no error. He then tried the 1.6 and the 1.9TDi software, both with the same results -no problem. I protested “How can that be? Look at my front tyres! Now that the car's tyres were eye-level the left tyre was almost just as bad as the right one. The technicians agreed that there is a problem and started speculating that if both my swing arm rubbers were uniformly perished the alignment would  technically still be in but the car would veer off the road and the tyres would run bald on either the inner or outer edge. They lifted the car higher and pushed a tyre lever into the control arm rubbers and convincingly said the one side is definitely broken.  Thank you very much and off I went.

Back at the VW service agents, 2 x control arm rubbers please. Yes, we have stock, R1200 (+/-$120) please. What! For two pieces of rubber? But since I needed it, I paid. Back home I jacked-up the car, placed it on car stands and stripped the front suspension until I removed said rubbers. By the way, I found the boots on tie-rod ends torn so back to the agents I went. "Sorry out of stock, expecting stock to arrive in 40 days". This was unacceptable so off to the local motor spares I went in search of tie-rod ends. I found them sold together with the control arm rubbers at R180 each, tie-rod ends R120 each. Everything together cost me R600 ($60), exactly half of what I already spent on rubbers alone. So after I fitted them to my Polo, I returned the Control arm rubbers to the VW agents for a full refund.  Amazingly the car now drives normal, no veering to the left or right and the alignment centre still says my alignment is normal, even though they or none of the other service centres they phoned have the software alignment settings for my 2.0L Polo highline. I now realise that she's an oddball.
