Audi V8 airbag control unit repair⁽¹⁾

What should I pay attention to with Audi V8 airbag control units?

The airbag control unit is the control centre of the restraint system in the Audi V8. It evaluates the crash sensors, triggers airbags and belt tensioners, and reports faults via the airbag warning light.

The control unit monitors the entire system, including sensors, igniters and wiring. A fault can cause the airbag warning light to stay on and the system not to work as intended in an emergency. Because the airbag is safety-relevant, a fault should be checked promptly.

After an accident, the control unit stores crash data and locks itself. Airbag24 repairs the submitted airbag control unit of your Audi V8 and works on your own unit. If necessary, this includes erasing the crash data.

Which Audi V8 generations are there?

The Audi V8 was built from 1988 to 1994 in the D11 4C series. For assigning your control unit, the construction period, model year and part number are therefore what counts.

• D11 4C (1988–1994) – Audi V8 of the D11 series, among others with 3.6 and 4.2 litre engine

The Audi V8 production period ended in 1994. Within these years, control units can differ depending on model year and equipment, so the model year is helpful when requesting a repair.

The Audi V8 was a luxury flagship model of the Audi brand. When requesting a repair, have the model year, engine and equipment of your vehicle to hand.

How do I identify my Audi V8 airbag control unit?

The part number on the label of the control unit determines the exact version. Also check the model year and equipment of your Audi V8 before sending in the unit.

The label shows the part number, which clearly identifies the version of the control unit. According to our records, the Audi V8 control unit comes from the supplier Bosch. A part number recorded in our records for this model is:

• 4A0959655

This list does not claim to be complete. If the number on your label differs, please state it in your repair request.

As examples, we list the fault codes 65535 (control unit defective), 00588 (igniter, driver's airbag, resistance fault) and 00589 (firing circuit, passenger airbag, resistance too high). However, a single code does not prove a defect. It is an indication that a specialist workshop should check.

What airbag equipment does the Audi V8 have?

According to an equipment overview, driver and front passenger airbags are standard equipment on the Audi V8 3.6. Side, head or knee airbags are not clearly documented for this model.

Which airbags are actually fitted in your vehicle depends on model year, engine and market. The exact equipment can be confirmed via the vehicle identification number (VIN) with the manufacturer or at a specialist workshop.

The route to repair: first have the fault memory read out. Then the battery is disconnected and the control unit removed, preferably by a specialist workshop, as only specialists should work on the airbag system. Then create a repair order online and send the unit to us.

Processing usually takes 3–4 working days: checking, repairing and testing. The repaired control unit returns with all vehicle data and is ready for use immediately after reinstallation — no coding or programming is necessary.
