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 TT RS 8J9 Roadster airbag control unit?
The airbag control unit in the Audi TT RS 8J9 Roadster monitors the restraint system (SRS) at every start and while driving, and reports faults via the airbag warning light. As the central control unit, it evaluates the signals from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners deploy.
As soon as the ignition is switched on, the control unit runs a self-test. If it detects a deviation at that point or later while driving, it stores a fault and switches on the airbag warning light. The control unit is installed in the Audi TT RS 8J9 Roadster (2009 to 2014). The control unit is made by Bosch. As part of the restraint system, it works together with the sensors, the airbags and the seatbelt pretensioners.
After an accident, the control unit stores crash data and locks itself. The airbag warning light in the instrument cluster then tells you that the system is no longer ready.
Why is the Audi TT RS 8J9 Roadster airbag control unit defective?
The most common cause is crash data stored after an accident, even if no airbag deployed. Other causes in the Audi TT RS 8J9 Roadster are aged electronic components, cold solder joints, moisture and corrosion on connectors, and voltage spikes.
Stored crash data cannot be cleared with an ordinary diagnostic tool. The control unit therefore stays locked even if you repaired the damage to the vehicle long ago.
In addition, components can age over the years. Cold solder joints cause intermittent contact, moisture and corrosion on connectors disrupt signal transmission, and voltage spikes, for example from a weak battery or a jump start, can damage the electronics.
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.
Common error codes for Audi TT RS 8J9 Roadster airbag control unit repair
The error codes in the Audi TT RS 8J9 Roadster indicate internal faults of the control unit, problems with the power supply and faults in the squib circuits of the airbags. Which code is stored can only be read out with a diagnostic tool.
The following list shows error codes that occur on this vehicle in connection with the airbag control unit.
- 65535 → Internal fault in the airbag control unit
- 00532 → Supply voltage too low, intermittent
- 00588 → Driver airbag squib, resistance fault
- 00590 → Front passenger airbag squib, firing circuit fault
- 01217 → Front side airbag squib, driver side, resistance fault
- 01218 → Front side airbag squib, front passenger side, resistance fault
Error codes are read out with a diagnostic tool. A code alone does not reliably show that the control unit is defective: connectors, 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 TT RS 8J9 Roadster airbag control unit repair?
The part number is printed on the label of the control unit and determines the exact version, because within the Audi TT RS 8J9 Roadster model range there are different numbers depending on equipment and year of manufacture. You will find it directly on the unit once it has been removed.
The following list shows known part numbers and makes no claim to completeness.
- 8J0959655 (Bosch)
Compare the number on your unit with this list. This only confirms that it is the right unit. Whether it is defective is only shown by reading out the fault memory or by the inspection.
How to get your unit repaired: first have the fault memory read out, disconnect the battery and remove the control unit. Then create a repair order online and send in the unit. Processing at Airbag24, including inspection, repair 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.
