My 320d (2000,W) Recently had a new injection pump fitted, the old one failed because of contaminated fuel (so I was told) since then starting the car from a warm engine can be really difficult, I have to turn the key 3-4 times before it starts, then is followed with clouds of smoke. Although from a cold engine it starts no problem at all. The garage that fitted the pump said that the contaminated fuel might have done internal damage, but they can't say what with out stripping the engine down. Has anyone come across this problem before, do you think that I should get rid of the car before anything else goes wrong?
