Problem I have is, my mk4 6N 16v has a set of keys...
The engine i'm fitting is the 1.6 16v which has the ECU, loom, transponder and key too...
My question is:
Are the ignition switches between the mk4 and mk5 the same, and what would you recommend??
Right now i'm thinking of taping the GTI key permanently to the transponder so the engine will start with my old keys turning the ignition switch...
Does anyone know if this ecu can be mapped to bypass the immobilisor???
