Volkswagen Electronics


VOLKSWAGEN ELECTRONICS

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.
