Hi all i have an a4 1.9 tdi 04 model and there seems to be oil leaking from my turbo.i also have an engine management light on.got a fault code p0236/7.is my turbo on its way out?i experienced limp mode the other day.it happened twice only when i stated the car not while i was driving.a restart sorted it.any one that can shed a bit of light on it i'd be grateful.

Were about is the oil leaking from under the turbo or from the top there is a flow and return oil pipe on the turbo that supplies the turbo with oil from the sump could be a oil pipe loose what the milage on the car any blue smoke The code you got is I think the map sensor also called the thrust sensor it is located on the intercooler pipe follow the pope from the cooler and it will be at the top with two screws in it get that changed make sure you get one from the dealer and get the car on ramps to find were the oil is exactly coming from could be your turbo seals but it should be smoking like hell

Did you have P0236 and P0237 or one or the other? What is your engine type code?

i have a simlar problem on a 2006 bxe 1.9tdi. no turbo boost and a permanant dtc of p0237 with pressure sensor plugged in and p0236 when i unplug it. but it also has oil leaking but it seams to be coming from egr valve.
turbo seems fine and so do all the pipes. we have fitted vw boost sensor but still same faults. could this fault be linked to maf sensor???

The BXE was only fitted to transverse installations such as Golf 4, Bora, Touran, Passat, A3 etc so why are you posting this is the Audi A4 8E section? The symptoms suggest a faulty turbo or vacuum system leak.

Hi Crasher, im working on the same vehicle.

OK we have a fault as soon as ignition is on p0237. will not clear!
Turbo turns fine not siezed
5.5v at the map sensor until i plug it in then it drops to around 2v
No obvious leaks
Wastegate will move with vac pressure
Cant see any damage to the loom...

Scratchin my head any ideas?? thanks jason

Crasher, passat 1.9 tdi 2006.. the large inlet pipe on the osf is collapsing when i rev the engine.... does that indicate the turbo is at fault?

[Crasher]

Yes, a classic symptom.
