Audi TSB #147320314585
2012 Audi Q7
Affected Component: BRAKES (PWS)
- Summary
- Under extreme driving conditions (such as short-distance, stop-and-go driving), high crankcase pressure can cause the DTCs to appear. The condition can be improved and the DTCs eliminated when the crankcase pressure valve is changed to a lower operating pressure and the ECM software is updated to compensate for new crankcase pressure.
