Somewhat unrelated:
I want to install a spare instrument cluster (used, no immo, no nothing available) in my 2002 AR (Immo3).
I figure there MUST be a way (even considering a trip to the dealer) to get another instrument cluster to work with my car? If how: how?
cheap ebay vag-com cable + vag commander 2.5 downloadable on internet will allow you to hack into the cluster and change VIN/Immo/Mileage.
You obtain the immo code by accessing ECU, the code is right in the ECU info string it sends out at the very beginning of handshake and is visible in VAG-COM for example as well as vag commander itself. It is also visible once you access one of the vag blocks in vag-com.
