    Default cdti sri throttle body butterfly

    Hi guys new to the forum an just got meself a cdti 1.9 (120). After owning 3 ford focuses an having 3 steering problems I thought time for somethin new. Got this for 1k as the seller said suspected turbo fail. Ran diagnostic in whichpointed to the pcb which controls the butterfly in body. Anyway I opened up an was absolutely full of oil to which I blasted cleaner in until spotless and car ran spot on. But this mornin it ran as in no turbo again an fault code said was this again. Sorry for going on but I suspect oil. On the contacts again. I've resoldered connections to. Does anybody know if there is a better way to seal this body part? Thanks guys

    Best remove the throttle body and clean it with carb cleaner. Make sure EGR is clean too

    I did them both an egr moving freely. Can diesel or oil actually makes it way down the butterfly shaft into the pcb inside?

    Yes it can but the problem on the earlier cars was more related to broken solder joints on the throttle body PCB.

    What is the fault code?

    The butterfly is an anti judder valve, Take off the corrugated right angle tube that goes from egr to throttle body lookalike, it will be gunk ed up, Some people have had oil residue in the bottom of the black box but as previous post says, dry joints are the main problem, Have another look in the black box, I dont think it would gunk up so quickly.
    have you cleaned your boost pressure sensor ?

    Cleaned boost sensor last night but I've come to another conclusio. I drove car after work an it began to work again but this mornin it stopped again. Could it be down to damp or cold in some connections in that area? Anybody else had this happen to them like this?
