P38 - BMW engine compatable...

i hate to burst your bubble my friend, but i fitted several pumps to customers range rovers and one brand spanky new one to my own and never had to code any of them. the only elecrical part of the pump is the fuel quantity control, the bottom end is still of the old design with the basic stop solinoid.even rave doesnt have a mension of the pumps being coded.

ABU,
Have you ever come across different flange sizes?
The only thing I can think of is if the donor engine is from a 325TD instead of TDS but even then it would be the first I've heard of a problem.
Then again, most people that change engines are doing it as a result of a head gasket and normally change the full lump.

Interesting.

in all honesty i have never come across the problem your having, the last pump i changed was taken from a vx omega and it went straight on the range rover like all the others. i got an engine to fit from a 325 in a range rover over the next few weeks, if i remember when changing it i will whip the pump off and measure the flange on it compared to the range rover one.

OK well I have changed the Injector pump after having the bits from the RR one into the BMW one as they were different... And I mangeged to get the car running runs sweet as a nut... Just need a fuel pump in the tank as mine is u/s. but all good now.. Didn't need to sync it in the end.

I've seen plenty of broken M51 bmw engines. Enough to know that there are two different pump flange sizes. A 68mm and a 50mm. Check the engines on BMW oem for the 325 or 525's if you dont believe me. Don't know why ye haven't come across yet
(although op did)
Also I swapped many 325's into 525's (TDS) over the years and had to modify the pump housing to accept the pump on some. Also Some pumps fire right up and others didn't ( had to install original pumps to get going.- something to do with the last 3 digits of the serial no's).

im not saying theres not two flange sizes, im saying there not a coded pump. the systems not canbus so no codes are used between ecu and pump. the flange size i have yet to experiance, i have got a 325 engine to fit in a range rover over the next few weeks so will pay particular attension to the pump. no need to spit your dummy out, no ones called you lyer.
