Hello, I wanted to code in AUX in my Audi A3 tfsi 8P 2005. When I connect the VCDS I can not connect to the specific modules. For some reason the auto-trans works...? The error message is: ""No response from controller" I managed to connect to the navi (37) for some seconds, but now I am completely unable. I know the instrument cluster was replaced some time before I owned it. Anything I can check or do? It worked fine in another car. Normal OBD2 with VCDS works fine, so looks like CAN-bus problem.
