Hi guys,

I'm trying to solve a problem with my 99.5 A4QTM
VAG Com won't connect and the factory 1551 is returning the error K Line to ground B+,

Does anyone have any idea how to fix this problem?
The symptoms (other than being unable to access the ECU) are:

Central locking is not working
Alarm won't activate

Thanks

Sam

I've tried with the newer VAG COM and the connector is showing red.

I have the stock radio but I wired an AMP in through the wiring harness in the Trunk that connects to the OE Amp.

Do you think that this would be enough to cause the fault on the K-Line?

Thanks again

Sam.
