Guys 2.0 TDi 140
Not sure how to describe this, so i hope it makes sense
Ill try and describe the symptons
while accelerating from stand still or being in a low gear the car seems to make a bellowing sound (first of all i thought this was road noise, but it does all the time unless i hardly press the throttle at all)
When i took more notice of the sound i also noticed the car seem to surge when this was happening almost like i was getting more boost for a split second.
I hope that makes sense. I have had the car nearly two months and it has done it from day 1, it doesnt effect my MPG i dont think, i get 650 miles to a full tank driving it normally. I have stripped the EGR and cleaned it even though it wasnt too bad and it may sound like a silly question but do these cars have a recirculation valve? could the diaphram be knackered?
VAG COM shows no errors also.
