Used MQB car check with OBDeleven

Check for mileage clocking indications, wear symptoms, common faults in MQB-platform based vehicles.

Basic Faults Scan

As you expect - star with a simple full scan. This will bring fault codes from all the modules in the vehicle.

Some amount of fault codes is nothing unusual. For example fault code B201A - SVM check. in 0x5F - Infotainment is expected if someone installed Toolbox, updated navigation maps, flashed newer firmware of the infotainment unit.

Uxxxx codes indicates that the module received a fault information from another module, that it relays on. For example if there's an issue with one of the wheel speed sensors connected to the ABS module, the ABS module will have the "master" fault code, and all other modules that relay on vehicle speed data provided by ABS module, will have Uxxxx fault code stored.

Do not clear found fault codes just yet!
