Airbag control unit Fiat 500 was broken. Hard to believe but they can really repair it! Recommendation!!
Automatically translated · Original: German
From the first phone call, the order processing, to the shipping, everything was done very quickly and professionally. Now I still have to send the repaired unit to the Swedish workshop and then hopefully the Honda can finally pass the HU there again (failed because of the red airbag light). Thanks to Airbag 24 in Berlin 👍👏. Gerd

What is an Audi V8 D11 4C airbag control unit?
The airbag control unit in the Audi V8 D11 4C is the central control unit of the restraint system (SRS). It evaluates the signals from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners deploy. It also reports faults via the airbag warning light.
The control unit monitors the system continuously while driving. After an accident it stores crash data and locks itself.
It is fitted in the Audi V8 D11 4C (1988 to 1994) and comes from Bosch.
Why is the Audi V8 D11 4C airbag control unit defective?
Most often the cause is crash data stored after an accident, even if no airbag deployed. A normal diagnostic tool cannot delete it. Other causes are aged electronic components, cold solder joints, moisture, corrosion on plug connections and voltage spikes.
Other causes are aged electronic components and cold solder joints. Moisture and corrosion on plug connections can also disturb the system. Voltage spikes add to this, for example from a weak battery or a jump start.
Typical signs are a permanently lit airbag warning light, a fault memory that cannot be cleared, or a diagnostic tool that cannot connect to the control unit. As soon as one of these signs appears, you should have the system checked, because a locked control unit will not deploy anything in an emergency.
Common error codes for Audi V8 D11 4C airbag control unit repair
Error codes are read from the fault memory of the Audi V8 D11 4C with a diagnostic tool. They show which area of the airbag system is disturbed: the control unit itself, the power supply or individual squib circuits.
First you read out the fault memory with the diagnostic tool. Then you match the display to the meanings. The following error codes occur frequently on this vehicle.
- 65535 → Internal fault in the control unit
- 00532 → Supply voltage too low, intermittent
- 00588 → Driver airbag squib circuit, resistance fault
- 00589 → Passenger airbag squib circuit, resistance too high
- 00590 → Passenger airbag squib circuit, second stage
- 01217 → Driver-side side airbag squib circuit, resistance fault
- 01218 → Passenger-side side airbag squib circuit, resistance fault
Error codes are read out with a diagnostic tool. A code alone does not reliably show that the control unit is defective. Plugs, wiring or an airbag module can also be the cause. Only the inspection clarifies where the fault actually lies.
What part numbers are available for the Audi V8 D11 4C airbag control unit repair?
The part number is on the label of the control unit. It determines the exact version, because within the Audi V8 D11 4C model series there are different numbers depending on equipment and year of manufacture.
The following list shows known part numbers; it should not be taken as complete.
- 4A0959655 (Bosch)
Compare the number on your unit with the list. This only ensures that it is the right unit. Whether it is defective is shown only by reading out the fault memory or by the inspection at Airbag24.
This is how to proceed: have the fault memory read out and disconnect the battery. Then remove the control unit, create a repair order online and send the unit in. Processing at Airbag24, with checking, repairing and testing, usually takes 3–4 working days.
The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
