TT Vag-codes ? Radio ??

[roydonaldson]

Hi there,

My wife's TT has a couple of faults in it: Fuel guage in cluster not working (though the eletronic miles left works) and the outside temp is weird.

Anyway, I connected Vag-Com up to it and pulled out:

Component: TT-KLIMAVOLLAUTOMAT D03
Coding: 00041
Shop #: WSC 01236
1 Fault Found:

30-00 - Open or Short to B+

* Address 22: AWD
Controller: 02D 900 554 C
Component: HALDEX LSC ECC 0010
1 Fault Found:
00526 - Brake Light Switch-F

* Address 56: Radio

Coding: 00000
Shop #: WSC 01236
1 Fault Found:

Any ideas on what's up ?

Thanks,
Roy.

Any idea where I can find the Air Temperature sensor in the Audi TT, so I can have a look at the connectors to it ?

Thanks,
Roy.

It's behind the front lower grille below the bumper and in front of the radiator.

I can see it. But how do I get near it ? Do I have to take that lower grill off ? How do I get at it ?

Thanks,
Roy.
