fuel injectors number 2, 3 and 4 have broken - number 1 was replaced last year.
Due to the estimate of £550, I decided to buy 3 injectors from eBay.
My friend, who is a mechanic has changed them over. He is a qualified mechanic (just left the army) so only has basic tools - no diagnostic kit.
The car won't start still.
The question is, do we need to programme the new injectors in with the computer?
The exact model is 320 TD SE COMPACT - 2002, 52 plate
Any help appreciated, thanks in advance.
