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.

VW ABS CODING

VOLKSWAGEN ABS DIAGNOSTICS

Using a code reader or  diagnostic tester to view your VW Polo ECU data is quite a treat and is also really cool. A view of the data just exudes the growth of motor vehicle technology in general and it is quite humbling if you are electronically minded and quite intimidating if you are mechanically minded.  However there is often the temptation to change a number or something, just to see what happens to your Volkswagen. If you are one of those people who just did that, I bet you have a wistful regret, wishing that you never did so in the first place because you got yourself a "01044 control module incorrectly coded error." Or perhaps you  swapped a 1996 VR6 engine into a 2007 MkV GTI chassis and got a "01044 control module incorrectly coded error." Or you had your car serviced and the ABS and ESP light stays on in the instrument panel and showing up as a "01044 control module incorrectly coded error."  Or you cleared that nagging airbag light on your VW Beetle, only to get a "01044 control module incorrectly coded error."

Control modules codings are normally NOT interchangeable since virtually every model among the numerous versions of  VW's  each have a different ABS/ESP module, Power Assisted Steerin Module, Climate control Module,  Instrument Module, Immobilizer Module and Engine Control Module and so many other modules. Taking this into consideration,  it is more than  obvious that one should NEVER copy coding from a different model VW, AUDI, SKODA or SEAT and paste it into your own Volkswagen, AUDI, SKODA or SEAT, unless you write down your original modules original coding so that you can revert back to it later, should things appear to go pear shaped. 

However if the two VW, AUDI, SKODA, or SEAT are the same in every respect, then  their module codings will be identical and therefore perfectly fine to use. Be particular about the module suffix since different suffixes signify different software versions which may not be compatible to your VAG car. Virtually each module that appears identical but has different letter suffixes will invariable have a different coding. So the rule is same car, same module, same module number, same module suffice, same coding. Disregarding this could incapacitate your car and cost you a huge amount of money.

Every Control module coding is stored as an onboard binary number, which in essence is the binary sum of the features for that specific module. Whereas the ECU also stores an onboard binary number which is the binary sum of all the Control Modules 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 notorius 01044 control module incorrectly coded.  Checksum verification was adopted by BOSCH Motronic ECUs to validate its EPROM's stored data. Having said that, 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. 

Below, is a list of VW ABS controllers and their respective coding which vary from  'ABS FRONT MK60 0101' to  'ABS 8.0 front H03 0002' to 'ABS 8.0 front H05 0002' to 'ABS 5.7 FRONT V20' to 'ABS 5.7 FRONT V30 ' to 'ABS/ASR 5.7 FRONT V20' to 'ABS 5.7 FRONT V00' to 'ESP 8.0 front H03 0001' to 'MABS 8.0 front  H04 0002' to 'ESP 8.0 front H03 0001' to 'ABS 8.0 front H03 0002' to mention but a few. Several VW, AUDI, SKODA and SEAT owners and mechanics are constantly searching the Internet for ABS module coding and hopefully this information may help them to get their Volkswagens, Skodas, Seats,  Audis and other VAG cars up and running once again.

VW POLO DIAGNOSTICS

VW DIAGNOSTICS

After I completed all the minor repairs (as can be seen in my previous blog) to my VW Polo 2.0L Highline she finally went for her 90 000 kms service. But hardly did I get her back when I heard a very soft and occasional "ting, ting, ting" coming from the right front wheel. The sound was difficult to identify at first, not even the auto service technicians at the center could hear it. I found that the wheel had a few millimeters of sideways play when I jacked-up the VW Polo. This prompted me to check all the nuts & bolts and I found the nut on the tie-rod end to be loose. After tightening it, the sideways play was cured. However, it didn't cure the soft, occasional and irritating  "ting, ting, ting."  Twice thereafter I had the wheel off but found nothing out of the ordinary. Anyway I suspect its the right right hand side CV joint that is starting to go but it kind seems strange that a CV joint should give up the ghost round about 90 000 kms, its just way too early.

The tough smart VW Amarok Double Cab.

The 2.0L VW Polo right hand side drive shaft is very different from that of its siblings, it is much thicker and the spline that the hub slides onto, is much coarser that any other VW Polo. This drive shaft is an agents only item and its not cheap and to replace it by substitution to get rid of the occasional "ting" is a bit extravagant. My VW Polo is a very different beast from the rest of the VW Polo range and finding information for it is quite difficult. It seems every service centre has all the other manuals except that of the VW Polo Classic 2.0L highline.

However the Axx, Bxx rule isn't hard and fast or cast on stone. There are VW Polo vehicles manufactured prior to 2005 with BMD, BME, BBY, BKY, BBZ, BAY,BLT engines fitted and there are some manufactured after 2005, fitted with AXU,ATD, ASY, AXR, ASZ engines.
