Audi Coupé airbag control unit repair⁽¹⁾

What should be noted about Audi Coupé airbag control units?

The airbag control unit in the Audi Coupé analyses the crash sensors, triggers the airbags and monitors the entire airbag system. If the system detects a fault, it reports it via the airbag warning light.

The control unit is the heart of the airbag system. In a crash, it decides which airbags and – depending on the equipment – which belt tensioners are triggered. A fault can mean that the system does not work as intended in an emergency. For this reason, any problem should always be checked by a specialist workshop.

After an accident, the control unit stores crash data and locks itself. Airbag24 repairs your own control unit, which you send to us, and erases the crash data during the repair.

Which Audi Coupé generations are there?

Our data lists one series for the Audi Coupé: the B4 range with type code 8B, built from 1991 to 1996. The type and year of manufacture help to assign the correct control unit.

The series can be identified by the type code 8B and the year of manufacture. Within the range, control units may differ depending on the year of manufacture and equipment.

• B4 8B (1991–1996) – Audi Coupé of the B4 range with type code 8B.

The build period and type code can also be checked in the vehicle registration document.

How do I identify my Audi Coupé airbag control unit?

The part number on the label of the control unit determines the exact version. The year of manufacture and equipment of your Audi Coupé are also important.

The part number is the most important clue. Compare it with the following numbers from our data. The list does not claim to be complete:

• 8A0959655A
• 8A0959655B
• 8A0959655C

According to our data, the manufacturer of the control unit is Bosch. Fault codes give clues about the affected circuit. Examples from our fault code list for this control unit include 00588 (driver airbag igniter), 00589 (passenger airbag firing circuit) and 01217 (front side airbag igniter, driver side). A single code, however, does not prove a defect.

What airbag equipment does the Audi Coupé have?

The fault codes for this control unit relate to igniters for the driver airbag, passenger airbag and front side airbags. Which airbags are actually fitted to your vehicle depends on the year of manufacture and equipment.

The driver airbag is located in the steering wheel. Whether a passenger airbag or side airbags are also fitted depends on the vehicle. Check this in the equipment list for your car, or ask a specialist workshop.

The control unit is the central unit that coordinates the triggering of the airbags in an emergency. A defective control unit is therefore a safety issue. Testing and repair should always be carried out by a specialist company.

Here is how the repair works: have the fault memory read out. The specialist workshop then disconnects the battery and removes the control unit. Then create a repair order online and send the unit to Airbag24. 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 as soon as it is refitted — no coding or programming is required.
