Hi everyone ive just swapped a 1.6 turbo engine in a one series bmw with a 1.6 twin turbo engine block and head. I've used all of the ancillaries off the old engine and put them on to the new engine, including all the sensors. The problem I'm having now is it won't start!
Will it need to be reprogrammed now?
I was under the impression that i wouldnt need to have it reprogrammed because ive used everything off the old engine! The only thing thats different is the engine block and the cylinder head, but I'm no expert! So if anyone can help me out on this then it'd be greatly appreciated.


Many thanks Mick
