Have a 2000 Passat V6 5spd, Tried VW Vortex, with no luck, figured it would be the as an A4 30v... Recently ran the codes, and this is what I came up with under engine.
9 Faults Found:
17833 - EVAP Purge Valve (N80): Short to Ground
P1425 - 35-10 - - - Intermittent
17880 - EVAP Leak Detection Pump: Short to Ground
P1472 - 35-10 - - - Intermittent
17843 - Secondary Air Pump Relay (J299): Short to Ground
P1435 - 35-10 - - - Intermittent
17938 - Camshaft Timing Adjustment: Short to Ground
P1530 - 35-10 - - - Intermittent
17829 - Secondary Air Injection Solenoid Valve (N112): Short to Ground
P1421 - 35-10 - - - Intermittent
17923 - Intake Manifold Valve (N156): Short to Ground
P1515 - 35-10 - - - Intermittent
17529 - Oxygen (Lambda) Sensor Heating Circuit: B2 S2: Short to Ground
P1121 - 35-10 - - - Intermittent
17525 - Oxygen (Lambda) Sensor Heating Circuit: B1 S2: Short to Ground
P1117 - 35-10 - - - Intermittent
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-10 - - - Intermittent

Tried searching, but didn't come up with an exact fix!
Do these components share a common ground, or connector, I imagine it is a simple fix. just wiggle fuse, or ecu connector? Or does anyone have a copy of the wiring diagram?

TIA

anyway, that is a lot of stuff to be reading shorted to ground at once, which makes me think that the logical place for the problem would be the point in common, or alas the ECU. Just a guess though, good luck with it.

i also am having the exact same problem with my 1999.5 A4 2.8 quattro 30V. i am coming up with the exact same codes. my car did this after crosing a..... SOB!, 10 inch puddle/ river of water during a rain storm last week. i am going to swap out the relay for the air pump and see if it controls the rest of the equipment.

i believe i found the problem. after tracing the wiring diagram i found that all of the trouble codes are on the same circuit. i traced mine down to a bad fuse #29(fuse in fuse box next to drivers door) coming from the fuel pump relay. other things to check in line with the circuit secondary air pump relay and fuse( in ecu box under hood drivers side). i hope this helps you.

Hello,
I am having the code 1472 after a plug bolt in my pre cat came out and the exhaust burned the o/2 wires I am also having variouse o/2 codes I have redone all and suspected a common thread I did chech # 29 fuse to fuel pump and it was good but after removing and reinstalling the car improved weird I never had any problems before the burn I hope it didnt permanatly effect the ECU ? Thanks for all the input Johnny

MUCHAS GRACIAS
