Hello-

I have a 2001 Audi TT. The car doesn't connect to OBDC, so I can't get my inspection sticker.

I got a VAG-COM KII-USB, which tells me that K1 is Short to Ground. There's no power to the K-Line pin.

I checked all the fuses in the main fuse panel, I couldn't find any issues. The car has the original Bose radio, which I pulled out and the fuse on it seems fine. With the radio out, I still have no K line power.

I also tried disconnecting the battery and reconnecting it, no luck.

What else should I check? Any help would be greatly appreciated.

Thanks!

Any of the diagnostic capable modules in the vehicle could be causing the K line short to ground. Unplug each one and test until all of the modules have been ruled out, or the problem is found.

If the vehicle is AWD don't forget about the module under the car. This is a list of the modules that this platform TT could have installed:

Thanks so much for your reply.

I will try disconnecting the control modules.
