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 A6 4GH Allroad airbag control unit?
The airbag control unit in the Audi A6 4GH Allroad is the central control unit of the restraint system (SRS). It receives the signals from the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners deploy.
So that this sequence works in an emergency, the unit continuously monitors the entire system, that is, the sensors, squib circuits and its own power supply. If it detects an irregularity, it shows this via the airbag warning light in the instrument cluster.
If it has registered an accident, it stores the crash data and then locks itself. It is installed in the Audi A6 4GH Allroad (2012 to 2018) and acts as the link between the sensors and the components that deploy.
Why is the Audi A6 4GH Allroad airbag control unit defective?
Most often the cause is crash data that remains in the unit after an accident, even if no airbag was deployed. Other causes are aged electronic components, cold solder joints, moisture and corrosion on the connectors, and voltage spikes, for example from a weak battery or jump-starting.
An ordinary diagnostic tool cannot remove the stored crash data. Regardless of an accident, the components on the circuit board also change over the years, and solder joints can develop fine cracks.
Three things usually point to a problem: the airbag warning light stays on permanently, the fault memory cannot be reset, or the diagnostic tool does not establish a connection to the control unit.
Common error codes for Audi A6 4GH Allroad airbag control unit repair
The codes that occur on the Audi A6 4GH Allroad point to communication errors, to problems with the power supply, to faults in the squib circuits or to an internal defect of the control unit.
The overview lists codes that actually occur on this model. They range from communication and power supply to the igniters of the front and side airbags.
- U1100 → Communication error with other control units
- U1101 → Communication error with other control units
- 65535 → Internal fault in the airbag control unit
- 00532 → Supply voltage too low, intermittent
- 00588 → Resistance fault in driver airbag squib circuit
- 00590 → Fault in front passenger airbag squib circuit
- 01217 → Resistance fault in driver-side side airbag
- 01218 → Resistance fault in passenger-side side airbag
Error codes are read out with a diagnostic tool. A code alone does not allow you to conclude with certainty that the control unit itself is defective, because connectors, wiring or an airbag module can just as well be the trigger. Only the inspection shows where the fault is located.
What part numbers are available for the Audi A6 4GH Allroad airbag control unit repair?
On the label of your control unit you will find the part number, which determines the exact version. Depending on equipment and year of manufacture, different numbers exist within a model series, so you should look at the label before sending the unit in.
The following numbers are known for the Audi A6 4GH Allroad; this compilation is not complete.
- 4G0959655A
- 4G0959655B
Hold the number on your unit next to this list. The comparison merely confirms that you have the right unit in front of you. Whether a defect is present only becomes clear from reading out the fault memory or from the inspection at Airbag24.
The route to repair looks like this: first have the fault memory read out, then disconnect the battery and remove the control unit. After that, create a repair order online and send the unit in. At Airbag24, checking, repairing and testing usually take 3–4 working days, and you receive your own unit back.
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.
