update people,

Ran the car for a while, temp went upto 90 deg and stayed there.

Pluged the scanner in and still got the same fault

Every so ofter the lambda sensor code woud come up saying - low end
I understand this is to do with the misture running rich ? am i right ?

The sensor (part number 06A 905 161 B, £112.27 from Audi) requires the upper cam pulley to be removed (or pulled nearly off) so it can be changed.

Thanks crasher!,

How do you go about pulling it nearly off? is it a hard job ?

[Crasher]

If you pull the upper pullet right back along the camshafts woodruff key you may be able to get the sensor out from between the chopper blade on the pulley.

Sorry to jump on this thread but I've got the same problem. I've changed the cam sensor but same error comes back? What els could it be? I've changed the coil. Could it be worth changing the plugs?
Car failed the MOT on emissions so am desperate to get this sorted now.

[Crasher]

What is the exact fault code you are getting and the cars details?

[Rhys0_0]

Same as above crasher 00515. It's a 1.6 2000 A3.
Runs ok cold but misfires slighty when upto temp.

[Crasher]

There are two versions of the fault code, which one do you have?

00515 Hall sender

1) G40 No signal
2) Implausible signal

[Rhys0_0]

It's the Implausible signal one.
