Hi Robert,

you may have some other troubles concerning the wiring diagrams because you are (propably) driving a right-driven V8 which has some things like the Audi 200 and some like the Audi V8. It maybe that the wiring is exactly the same like on a left-driven V8, but keep it in mind!

I don't know if you've already read out your error memory of the Motronic using the diagnostic interfaces located on the left side in front of the passenger seat, under the carpet. It's always a good point to start.

Anyway I can also imagine that there are problems with the security system although I'm not really experienced with the system.

Regards

Bastian
