Ive been having problems with my Vectra 1.9 cdti 150.
I posted on the vvoc forums but was advised to come here. I've done so much reading up on the problem and I just can't seem to get anywhere. Here is the jist of what I have done..
I have a Vectra c 1.9 150 pre-facelift. I only bought the car a few weeks ago but after a long drive to Scotland I noticed a few flat spots. I have taken the engine cover off and looked in the inlet manifold area and it seems the rail that connects the swirl valve/flaps has come loose (I can move it around freely with a long screwdriver).
Am I causing any long term damage to the car driving it in this state? It boosts fine, pulls well and the flat spot is only noticeable if you tootle along, it happens at around 1900rpm.
An update to this - I got my OPCOM working and checked, there were a few faults to do with the display and a high voltage to the drivers door, I cleared them, drove down the road and its now in limp mode. Rescanned and opcom is showing no faultsSorry for the wall of text. I appreciate any help as I am quite worried now as I can't afford another car or hefty garage bill
I took my EGR off and gave it a big clean with carb cleaner and also the part on the inlet manifold that was caked in carbon. Also gave a quick spray down my air pipe. Put it back together and started it up n it was horrible - cut out after 20 secs.
I used my opcom and found faults for maf, EGR etc.. I then realised I forgot to plug the sensors in. Plugged them in, cleared the faults and it was giving me more trouble with error p0090-5b. As the car was parked facing uphill the small amount of fuel I left in there before limp mode wasn't enough, or so I thought. Off to the petrol station with a jerry can and put some more fuel in. It now started up, BUT it was really lumpy and smelly, sounded terrible and was shaking the car. Only way I can describe it is like a loud knocking and the shaking is similar to that of if you had your bottom engine mount off and the engine wobbles.
I'm now at a loss as I don't want to damage the engine but there aren't any faults in opcom.
I think I have been done over when I bought the car this is going to end up costing money I can't afford
