VAG-com Codes and ground wire help

[IgorBoi]

So I had my car checked on a vag com and I am getting a lot of codes that say short to ground. I was wondering if anyone knows a diagram of all the engine ground wires, so I can check and see if they are connected properly. I tried searching for it, but found nothing.
Here are the codes that I get, if anyone has any sort of idea what it might be, please do tell. Thanks in advance!

17833 - EVAP Purge Valve (N80)
P1425 - 002 - Short to Ground
17525 - Oxygen (Lambda) Sensor Heating Circuit: B1 S2
P1117 - 002 - Short to Ground
17843 - Secondary Air Pump Relay (J299)
P1435 - 002 - Short to Ground
17829 - Secondary Air Injection Solenoid Valve (N112)
P1421 - 002 - Short to Ground
17697 - Boost Pressure Control Valve (N249)
P1289 - 002 - Short to Ground
17880 - EVAP Leak Detection Pump
P1472 - 002 - Short to Ground
16486 - Mass Air Flow Sensor (G70)
P0102 - 002 - Signal too Low
17523 - Oxygen (Lambda) Sensor Heating: B1 S1
P1115 - 002 - Short to Ground

suggest checking the wires in the harness, short to ground means that the wires are grounding out when they are not supposed to. as in a live wire is coming into contact with a ground.

if there was no ground it would be open circuit.

If I recall correctly the N80, n75, maf, SAI and all those things share a ground that eventually meets up behind your coolant tank.


start looking there.
good luck
