4.2 quattro tdi in the a4 cab?
will the 4.2 quattro tdi engine from the A8 or the Q7 fit in the b7 audi a4 cabriolet quattro 3.0 tdi that i have? how much messing about would it be or would it simply noy fit the chassis?
It may fit, but I think you will be in a world of pain when it comes to the electronics. The electronics on the A8 require can gateway module, which you don't have on the B7, so good knows if the ECU would talk to the B7 immobilizer & instrument cluster without it!
