Anyone having a slight flat spot/hesitation sometimes?
Never whe cold for some reason? it only does it intermitantly
2l crtd 02 plate (early model)
Checked the basics and all seems ok ,no fault codes did have problem with EGR valve a while ago and this fixed a similar problem ,this seems like a slight air ingress in the induction system but have not found anything anyone have any ideas

Clean the MAF sensor with brake carb cleaner or similar first.

Your welcome. Carrying out that work has resolved a lot of running problems on a lot of turbo diesel's.

Hi. Where exactly is the MAF sensor and is it easy to remove to clean it. I have exactly the same problem with my Trajet. Thanks David

Standing over the engine to your right is a large squre box (air filter housing ) off it comes a 4 inch in diameter rubber hose going to the engine ,about 3 inches from the housing is a bit with a wire multiplug going to itMAF .Remove the jubilee clips from either side and remove. with it removed spray carburettor cleaner into it at the bit sticking out in the middle ,spray liberally LEAVE IT TO DRY FOR 5 MIN DONT FIT IT STRAIGHT AWAY OR YOUR ENGINE MAY SCREAM WHEN STARTED. Now re fit and all should be well

Any probs just say :beer:
