I own Golf 5 2.0 TDI, year 2006 which was crashed. I replaced complete engine and ecu with 2008 from the car which was burned inside. Original type motor was BMM, the new one is AZV. The problem is: the engine starts for a second and on the board computer says Immobilizier active! Could I solve the problem myself with vcds diagnostic tool? Thanks for your time and your help.
