Hoping to find a little help on this forum about the Mrs 03 Scenic. Ive always thought its been a little slow ever since first ownership some 6 years ago! Now Ive been forced into driving it I'm fairly sure something is amiss. The car starts and drives ok, no fault lights or anything, its just gutless! Theres no torque in it. It almost feels normally aspirated.
So I set about checking it over suspecting maybe the boost pressure was low, however to my surprise its got good boost pressure. I now am suspecting perhaps theres not enough fuel getting in as even if you mash the throttle theres no visible black smoke at all. This Ive never seen before from a diesel.
Ive never touched the EGR valve, but had no reason to suspect it. Would an EGR valve fault cause these symtoms tho? I always thought it would be really obvious that it was running bad if that was faulty??
It had a new air flow meter some years ago but didnt make any performance change ( is it called that? the inline one behind the airbox).
Any thoughts/ideas? Anyone think my assumption is correct its not getting enough fuel? If soHow do it fix that??
Thanks
