Took car in for VAGCOM and got these faults, ive looked all over the forum for answers, found the same questions but know answers. please can some advise on how to fix these.

01257 - Idling speed stabilization valve -N71 Open/short circuit to ground (GND)
Where can this be found and do i need a knew one, what does the GND mean?

01262 - Solenoid Valve for charge pressure -N75, same again to ground.
This is under the air filter near turbo, But does it mean a wire is loose or do i replace it?

00516 - Throttle position switch, open/short circuit to B+!!!!!!

00513 - Engine spped sender - No signal i noticed L200 had this problem and replaced it please advice.

GND = ground/earth

sounds like you've got some wiring problems

[mathewellwood]

so does that mean there not actually nakered, its just the wiring thats a bit dodgey.

[CliveH]

Could just be the wiring or the contacts that need cleaning.

Check that out before you start replacing.

Regarding this one

00513 - Engine spped sender - No signal i noticed L200 had this problem and replaced it please advice.

That will display if the car is vag-Com without the engine running.

Clear the codes, start the engine and re-Vag-com and see if the code comes back.

mmmm

the people at hadwins audi, said they cleared the faults and they came up again and they still apeared so must be an actual problem. but cheers il check fuses. do u think an autoelectrician will be able to fix all the groundings or is it more of a specialist job

If the fuses are blown it will give those errors or if they aren't connected properly

For an explanation of the codes and possible problems cross reference here.
