    Case Study B13BC - Multiple collision brake: No function

    ST?ID=91869

    2019 Q5, hit pothole, rack was damage and replaced. Airbag has B13BC. ODIS run on it several tries, no luck.

    We tried airbag Basic Settings Reset analysis measured values and from that, the B13BC went from a hard code to intermittent and was able to clear out.

    2018 Q5, similar story, some mishap but no airbags deployed, power steering rack busted up and replaced. Airbag had the same B13BC - Multiple collision brake: No function. Fresh key cycle, went into airbag and did Basic Settings "Calibrate installation location". He George didn't notice finished correctly, just not running. [Stop] and backed out of Basic Settings and was able to clear the code out.

    So.... is this a fault code to expect when replacing the J500?
