Was hoping someone could help me and give me a bit inside info. Runing a Vectra sri (150) 1.9cdti. Seems to be losing power and seems really flat especially under 2000 rpm. I know there are issues with no pull low down the revs before the turbo kicks in but this is different. The turbo was kicking in at 1500 rpm but now seems to come in later (about 1900) but car has definetely lost some umph. Even when turbo kicks in it is definetly flatter than usual. Going to ring dealers tomorrow but worried coz i'm driving to France next week. Any ideas anyone in case dealer is not very helpful??
