Ok so my vectra c diesel has a lack of power and is cutting out every now & then
possible jobs need doing....
cleaning out EGR valve
cleaning out Boost valve thingy...
Iv already cleaned out the throuttle body and added a made up gasket with some holes to block the egr (helped but problem still persists)
possibly need a new fuel filter???
here is a picture of a matching engine bay
can someone tell me what they think it is and where its located??? many thanks
