This bulletin applies to 2011 Audi A8 vehicles. While scanning the vehicle with GFF, the entry B120216 reversible belt tensioner voltage too small to address code 90 and 8F may be stored.
This is an incorrect diagnosis which can occur if different signals coincide in a very short time.
The operation of the reversible seatbelt tensioner is not affected by this fault code. To address the concern, clear the fault code in GFF and update the software with new version 080.
