Hi all
I have a Passat 2006 2.0TDI sport manual transmission with a BKP engine. The engine has lost compression one on cylinder and has been deemed to be scrap. My mechanic friend has a BKD engine from a Golf. He is confident it will fit physically but is unsure if it is compatible - Turbo/ECU etc. He doesnt have the ECU form the BKD engine.

Any and all help would be very much appreciated as I have just spent £800 on shock/springs and bushes and am keen to keep the car on the road.
