2.5Td diesel injector pump
« on: 15 November 2007, 16:38:05 »
Just wondering if all the 2.5Td injector pumps are all the same. Also are they all the same on the 2.5 BMW. If not are they interchangable?

Also where is the best place to get one second hand?

as i understood it pumps are all the same but the sensors are management specific? i.e an later pump wont run an earlier engine due to differnces in the pump signals?

In BMW documentation there is a note that a newer pump can't be used on an older ECU (think that is the right way round).

So the older pump & potentiometer can be used on a later version? Is that right? I have been trying to get a spair one from loads of places and know one has one, just would like to try changing to see if this cures my problem, may also change number 3 or 4 injector, the one with the sencer on, to try and eliminate things.

I believe so.  My BMW info is not currently installed.

The injector with needle sensor is No 4, and the electrical connector does vary with age.
