Do you notice any lack of power, smoke on accelerating or a whosing noise. If so check the pipes form the turbo to the inlet ( mine had a split pipe between intercooler and EGR) causing loss of MPG amongst other probs.

on the air intake you should see a square bok with two wires onto it this contains the maf

no i cannot see anything on the air intake pipe ? dont think its got one .. i have seen pics of others with one

the cars runs well , tick over ok no smoke , ive cleanthe the egr valve out today and the inlet manifold , there was abit of gunk in there ? put it back togeather en runs ok ,, still only getting 28 - 30 MPG , thow ,, wat else can i try ,

the car starts first thing , and seems to run good , had a look at the turbo pipe that normaly splits , cannot see anything wrong ? ive tryed injector cleaner , i use bp fuel and shell only / im going to change the fuel filter tomorrow as thats the only thing i aint changed ,, cannot see this improvving the fuel thow ??

bin on a good run to country lanes, getting over 40 mpg now so its getting better ? cleaning the egr valve must of helped ,, think short trips i use it for aint doing it no good ? and cold weather ,

on the cold air intake filter you should see a square bok with two wires onto it this contains the maf

Thanks for the tip. Finally, an idea has been generated by this post. I was figuring this out for a week now.
