My 2.2dti vectra had sat for about 5months before i got it. On a morning it struggles to start, takes 2 or 3 attemps before she fires up, and when she does she chucks a bit of smoke out the exhaust. It only does this in the morning, the rest of the day it will start 1st time evey time.
Its just had a fuel filter, oil and filter change last week but its still struggling to start 1st thing in the morning.
I have yet to see a glow plug light come on the dash (does the 2.2 16v dti have a glow plug light) once the ignition is turned on the oil and eml come on, the eml then goes off after a second or 2 but thats it.
