AUTEL D900 SCAN TOOL

AUTEL D900 SCAN TOOL

The modern day car in its current incarnation has increasingly become more and more electrotechnical than mechanical and technological advancements are constantly on the incline.  It is therefore  quite appropriate to say that vehicle owners need to become electromechanical savvy. In my opinion, the way forward is to invest in a scan tool for your particular make and model car. Since most people are familiar with Cell Phones, Decoders, Set Top Boxes, PVR, DVR and Televisions with various menus, or computers, access points and routers  with various wizards, navigating a scan tool would be relatively easy. A scan tool is an indispensable device for modern car diagnostics and is a technological marvel that's going to save you time and money, but only if you are willing to embrace the technology. 

In a previous blog I discussed VCDS which I think is a really fantastic piece of software with its hardware interface combination specific to VAG vehicles. The amount of Onboard information that is accessible with VCDS is astounding and it is literally beter than the factory  VAS Scan Tool used by VW /AUDI /SKODA / SEAT agents. In fact, in some cases VCDS  will even retrieve more faults than the VAS tools.  Be that as it may, as fantastic as VCDS is, it has major shortcomings for vehicle owners in general. Since VCDS is VAG specific, all other vehicle owners are at a loss to its technical capabilities and would have to look at other scan tools from  companies like  Auto Boss, Launch X431, Autel Maxidas DS708, Pro-Link iQ,  Mentor Touch ET6500, OTC Pegisys, Craftsman - 20899, G-Scan Oceania, Bosch 3824, etc, who produce commercial multivehicle scan tools. These companies cater for the automotive service industry since their scan tools are quite pricey and far beyond the budget of the average car owner.  If VCDS was multivehicle, it would be as good if not better than most commercial scan tools. However, since this is not the case,  Autel has come to their aid of the average car owner. Autel has a low cost handheld scan tool that is multivehicle compatible that supports the following list of vehicles.

Acura, Audi, BMW, Buick, Cadillac, Chevrolet, Chrysler, Daewoo, Dodge, Eagle, Ford, Geo, GMC, Honda, Hummer, Hyundai, Infiniti, Isuzu, Jaguar, Jeep, Kia, Land Rover, Lexus, Lincoln, Mazda, Mercedes Benz, Mercury, Mitsubishi, Nissan, Oldsmobile, Pontiac, Porsche, Plymouth, Saab, Saturn, Scion, Suzuki, Toyota, Volkswagen, Volvo.  

I acquired the 2015 version because of its versatility because it supports several models of each of the above mentioned vehicles. I wanted it to diagnose my Renault but discovered that it unfortunately does't support Renault and even more surprisingly it doesn't support my  VW Polo  2.0L Highline (9N) either but it does support the the following list of VAG vehicles.

Audi A3
Audi A4
Audi A6
Audi A8
Audi A8L
Audi All road
Audi Cabriolet
Audi S4
Audi S6
Audi S8
Audi TT

Volkswagen Beetle
Volkswagen Bora
Volkswagen Eurovan L5
Volkswagen Eurovan VR6
Volkswagen Golf A3
Volkswagen Golf A4
Volkswagen GTI
Volkswagen Jetta A3
Volkswagen Jetta A4
Volkswagen Passat
Volkswagen Touareg

I don't know if the previous years version (Autel D900 2012) supports older vehicles like 2002-2010, but am of the opinion that all newer scan tools are backward compatible though I may be wrong. Anyway, the Autel scan tool is really cool, it comes with a mini CD containing a pdf file of all supported vehicles. I would have thought they would include a list of generic DTCs for Chassis / Powertrain (P-codes), Body (B-codes)  and Network (U-codes) for easy of identification. What this implies is that you will have to either find these lists online, save them as pdfs or print them or access the internet resources to identify the codes every time you car throws you a DTC.

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.

AUDI  MODULE CODING

Electronics has taken over the modern day car, a trend that started prior to 1994. Since then  motor vehicle electronics technology has taken on a completely different form. With the advent of OBD (On-Board Diagnostics) there has been strides to standardize automotive electronics in all vehicles with relative success. With the arrival OBD II automotive electronics standardization was close to uniform, however there were other derivatives, among which was EOBD (European OBD). Thereafter, CAN-Bus was introduced which is now the defacto standard for all cars built after 2008 internationally. All cars built from 2012 only sports CAN-Bus,  and are not backward compatible to older ODB II protocols, like KWP2000 for example. This move implies every auto technicians who financially invested in ODB II scanners will have to get the latest equipment in order to scan the latest cars. Just look at the Audi Q7 with its 50+ electronic modules all of which are CAN-Bus only. 

Audi Q7 has more than 50 Electronic Modules.

The hexadecimal list of Electronic Modules below are just an idea of what can be expected in current and future motor vehicles many of them having as many as 24 different module versions, many modules are incompatible with the various models of Audi, VW, Skoda and SEAT, each with its own features and coding.

VW AIRBAGS

VW AIRBAGS CODING

Virtually all modern cars are fitted with airbags and VWs or VAG cars are no exception.  Airbags are specifically designed to protect the driver and  passengers in the unfortunate case of an accident.  Having airbags gives drivers and passengers a certain sense of safety and assurance should they be involved in an accident that injuries sustained could be kept at a minimum. Airbags are manufactured from a parachute-like material and they instantly inflates with a compressed gas,  when the automobile in which it is fitted to meets with a collision.

However it is becoming increasingly common for airbags to deploy unintentionally, sporadically and spontaneously, completely  without the help of an accident. Even though airbags are designed to make drivers and passengers feel safer, in several cars the presence of an airbag  has the complete opposite effect. Airbags dashboard lights are also commonly lighting-up for no reason and without explanation. If or when the airbag on the dash board  lights-up, the system detected a problem and as a consequence sets an error code or trouble code. This implies that the airbag circuit isn't working properly and will not deploy in the event of an accident. When the airbag light comes on  for no reason, you should have your VAG car checked and  diagnosed by a trained technician because the airbag system is certainly not a D.I.Y item. There is no "reset" for an airbag system so NEVER attempt to repair it yourself since serious injury can result  if not done correctly.


Every time the ignition is switch on the system does a self check and should  it detect a problem, the air bag light is will be illuminated or flash. Repeated flashing  is actually the fail code being spelled out in a two-digit code. The light will pulse the first digit,  pause, then pulse out the second digit, pause again but for longer, then start all over again. Once the problem if fixed and the error code cleared the light will stay off.

Normally car code readers, scan tools and auto diagnostic testers omit airbag testing and interrogation unless specifically selected for fear that the diagnostic equipment or user error could trigger the airbags and cause personal injury. Numerous airbag malfunctions has occur during impact, amongst which are delayed deployment, partially deployment and complete failure to deploy. Several vehicle owners including VW, Golf  and Polo owners have complained to The National Highway Traffic and Safety Administration about airbag problems which could entitle them to a full or partial refunds for airbag problems experienced and in some cases even entitled to a new car replacement.

When a VW ends up in a crash, it stores the crash data which cannot be cleared with a VAG-COM. VW and the  airbag controller manufacturer intended it to be "unclearable" but rather replaced.  Normally the safety belts will have to be replaced along with the new airbags because the strain gauges and other electro-mechanical sensors inside them are unreliable once they have exceeded the G-forces limit at deployment.

MANIFOLD

MANIFOLD / EXHAUST

It was about 2:30 a.m. when I returned from a long distance trip. I was tired but smiled to myself before I climbed into bed because my 2007 VW Polo Classic Highline really performed well and brought me home without incident. I was amazed, blown away in fact. 

After breakfast the following morning, I intended to go to Milnerton to see a client but when I started the VW Polo, I was greeted by  frighteningly loud noise. I smiled too soon. Immediately I switched off the engine. It actually sounded like the VW Polo had no manifold system fitted at all. For the record it wasn't like the sound of a broken silencer or a hole in the exhaust system. It literally sounded as if there wasn't any exhaust system at all.

My first thought was that someone must have liberated my exhaust system during the night whist I was asleep and sold it off as scrap metal. Theft in my locality has become quite rife and this is known to have happened. Radiators and batteries seem to be targeted more often.  However, on closer inspection I was relieved that the exhaust was still there. I started the VW Polo once more rolled underneath the front suspension and discovered hot air was blowing from a space  where the flange gasket is located. It was very awkward to get my hand in there and I was wondering what this repair was going to cost. A trip to "Mister Silencer" and three hundred and twenty bucks later the VW Polo was once again ready for the road. I expected one of the dashboard EPC warning lights to light-up or one of the CanBus interconnected computer modules to immobilize the car but its seems that the manifold exhaust  just runs much too hot to attach a sensor to it.

Anyway, in order to fix or fit a new flange gasket the complete knuckle had to be removed. They hoisted the car on a maintenance lift and inspected its underside for the origin of the noise. It came from above the flexible bend which looked like matted wire mesh. Essentially the joint between the manifold branch and the exhaust manifold had to be removed.  I was told the flexible mesh compensate for vibration, should the silencer knock against a pavement of something, it wouldn't brake off of get damaged because of its flexibility.

Just two days prior to this, a young women ran into my rear bumper with her sparkling new look Audi A8 whilst she was chatting on her cellphone. There was no physical damage to neither of the cars but thought that she was the cause that my exhaust had given trouble. According to the dude at "Mister Silencer", its highly unlikely because the impact from behind would not have pushed the exhaust towards the engine because of its flexibility. Oh well,  either way I had to pay for it. FYI my VW Polo had every service on time since new and currently has 88250 Km on the clock. Soon it will be going for its 90000 km service and my timing belt will be changed. I've been driving with the dreaded fear that it might snap in mid travel and bend all my valves in the process or even bust the tops of one or two pistons.

In my first blog I mentioned I simply love German engineering because when a German designed car snaps a timing belt, there is no mechanical damage to the engine. This is so unlike the Japanese, American, English and French designed cars, all of which bend valves, bend conrods, break pistons or knock holes through their cylinder block. Since my VW Polo Classic 2.0L Highline is soooo different from all the previous German cars I owned, I just have this feeling it was designed along the same money making monopolistic ideology of modern car design - the cash cow that  sells spare parts.
