Hi everyone.
Is has been a while since I've lasted posted a message but I use the site all the time as everyone knows so much info its great to solve problems and find out new things to do with the vectras.

Anyway can some help. My car has been in and out of the stealers with an old problem that a few members have had already but I am still trying to solve. Please see pasted text from old thread:-
need some help on this. ! 46K 150 bhp CDTI. this car has had a lot parts replaced to try and slove a fault by the dealers. The problem is after the car has been resting for over 2 hours it starts up ruff and above ave. smoke comes out the back. I can stop this by either v lightly touching the acc pedal or un-plugging either the MAF, boost sensors to go to basic settings. Both of these sensors are new. the idle and smoke disappear within 10 secs and all seems ok.

The car does not do this when on a cold morning start and does not smoke etc after leaving it for 8 hours just anything upto 6 hours!! It,s not the turbo or injectors as that has been done as well.

Does anyone know what the solution to this problem is as my car has the exact same symptons. I have already had the EGR replaced and the car is getting a new coolant sensor next week. Do you think this will help or is it something else?

Thanks for reading folks ! Happy days
