Problem with Vectra CDTi engine

[Sean Peacock]

Hi

I have a 2007 Vectra 1.9 CDTi [150]. It is 4 months old and has 16,600 mile on the clock. Yesterday the engine appeared to lose power when accelerating at motorway speed. It feels hesitant to increase revs and the turbo does not kick in until approx 2250 rpm. It used to kick in at about 1700 rpm. Also it intermittently will not rev past 4000 rpm as if the rev limiter kicks in early. I have checked the air filter and oil levels and both are fine. I am setting off early tomorrow (Sunday) to drive it to Paris and so cannot get it looked at by a dealership.

If anyone has any ideas what may be wrong with it I would appreciate their knowledge.

Thanks

Sean

Has it recently been through the dealers? It sounds as if there might be air being drawn in to the low pressure side of the fuel system between the tank and the pump, possibly due to a poor filter replacement
