Unexpected New Audi Owner looking for advice on a 2000 A6 2.7. MPG is outrageous and VAG-Com pulled these codes twice. There also seems to be an excessive exhaust smell when running. No smoke though. Suggestions anyone?

p1425 EVAP Purge Valve:Short to Ground
p1472 EVAP Leak Detection Pump:Short to Ground
p1435 Secondary Air Pump Relay:Short to Ground
p1530 Camshaft Timing Adjustment:Short to Ground
p1421 2nd Air Injection Solenoid Valve:Short to Ground
p1121 Oxygen Sensor Heating Circuit: B2 S2: Short to Ground

Will be doing a TB job due to mileage on vehicle but was wondering if anyone had suggestions for the above codes. Excited to bring this Audi back up to par!

 

I didn't think 2000 2.7's had secondary air on them? Mine doesn't anyway. If it does not, ECM is talking out its **** and has some issues.

Common theme here though - same connector on the ECM for all of these? Maybe loose or damp? ECM got some emotional issues? Harness problem due to rubbing?

 

seems like you have a short.....
