Engine Replacement

[dhslider]

Hello, 
i´ve got a sharan with an engine that needs replacing and i was wondering if i replace the engine with one from a galaxy will there be any need to recode the immobilizer?

Assuming this is the diesel, if you keep the same ecu then no it shouldn't make any difference, needs to be the same engine type though.

Well im going from an 66kw to an 81kw ecu with the turbo and injectors

I would suspect you would either need to carry over the key (use the key off donor vehicle) or clone it that being the case. If they are both remote keys then you should be able to transfer the chip over and keep your existing key. Some vw bases use the speedo to store the key on, but I don't believe the Galaxy/Sharan does this as far as im aware. It would help others confirm this if you could give an idea of the years of vehicles involved as it may differ from earlier to later ones.

The 1.9tdi 66kw thats going in is 1996 and the original blown one is 1998. And would it work if i just swapped the high pressure pumps and if i did that how would i time it?
