Audi Airbag ECU B05cн 0285010856 4H0959655C - Sedat88 - 04-10-2026

Hi everyone,


I have a 2014 Audi A6 (WAUZZZ4G5EN032975)
with the following fault code stored in the Airbag control module.


B100911 - Driver side rear safety belt tension igniter (Short circuit to ground / Open circuit)

The issue is that the vehicle isn't equipped with a pyrotechnic rear left belt tensioner at all. Because of this, simply clearing the fault memory doesn't work—the code comes back immediately as a static fault.

Can someone clear this fault code for me?

This is not an airbag module!
