[jimquattro]

hi , im having trouble getting hold of a map sensor for my 1997 a4 1.9tdi quattro it is located inside the ecu and i think it is faulty as it is contaminated with oil from the tube that goes to it, can any1 help please i have the limp mode all the time and the vagcom says manifold presure problem 0575 i think

If yours is the 110 afn engine, the map sensor should be on the black pipe that
runs along the back of the engine and the rh side of the head.

Up to 97 it is located inside the ECU and I have not been able to source these but then again their failure is not common although on of my lads has the same car and his keeps registering as faulty. We have been trying to find out who makes them so we can solder in a new one.

yeah its definately in the ecu the newer models have it on the pipe at the back of the engine bay, ive got the part number bosch 0273 003 210 but cant find it for sale anywhere, how long you been lookin crasher?

[Crasher]

If that is the number, it is not good news.

Might want to double check the thin pipe that runs from the pipe at the back of the block to the ECU. Mine had been rubbing against another pipe and eventually produced a hole which gave me limp mode at high revs (same error code). In my case I only found it by doing a low pressure boost leak test. Fortunately I could cut the section out as it was near where it entered a rubber hose.

I was just talking to Matt my mechanic and he says that since he put a crimp on the end of the pipe and cut a frayed section off, it has not done it.

just got my car sorted no more limp mode! yay. wasnt the map sensor after all but the n75 valve or whatever you call it at the front of the engine bay by the vacuum ball, got 1 from the scrappy and cured it instantly
