Plausibility rail-pressure volume regulated warning????

[x555a]

Hi all i have just posted on a similar thread but thought i would ask hare aswell.
I have done a diagnostics check and it is coming back with the warning 'Plausibility rail-pressure volume regulated'
The problem is the x is cranking for a long time before finally starting and I am getting the 'Fuel injection systom' warning light coming up on the dash.
The x is a 3.0d btw as i know most on here are petrol.Any help would be great as i am stumped at the moment
Thanks for reading.

Most common issue with that error code is a faulty rail sensor pressure switch..

Hi and thanks for the quick reply do you mean part no 3 here....
RealOEM.com * BMW E53 X5 3.0d High pressure accumulator/injector/line

You said most common but would there be anything else obvious causing this? sorry for all the questions but i don't want to go spending another £180 on parts without checking all options.
Thanks again for your reply

With diagnostic error "'Plausibility rail-pressure volume regulated' "..this could be error codes P0001,P0002,P0003 OR P0004.Which is one is it?Depending on which one you have,you cause could be an open circuit,circuit range issue or simply a low/high circuit!
It could be the wiring,the connector ,or indeed the sensor solenoid as per your Realoem link.

Hi and thanks for the reply again the error warning shows '4560/21 - Plausibility rail-pressure volume regulated' on the scanner and may yet be the rail sensor etc......but since then i have found that the exhaust manifold is cracked so i will see what happens after i replace it.
I will post the outcome once done.

I have replaced the manifold and now all is well
Thanks powers1 for your help

What APITA of a job aswell

Glad you got it sorted

Weird though,it showing a fuel pressure error!Has this error gone now?Maybe you need a new scanner

Did you replace the exhaust manifold yourself?You are right ,its a hell of a job!
How did you find out how to remove the top turbo bolts?
Made even worst on a RHD car because the manifold is on same side as the steering wheel and the drive shaft has to be disconnected for you to take out turbo/manifold.
We dont get many cracked manifolds here,unless the car was badly re-mapped for really high EGTs (exhaust gas temperatures)

Scanners fine fella and yes the error has gone but i did replace the return fuel line from the injectors as it looked brittle and possible leaking which would account for the rail pressure.

Yes i did replace it myself and removing the turbo bolts was simple just use a long extension bar and a 13mm socket and no need to disconect the drive shaft either

Interesting about the EGT's though with bad re-maps didn't know that

Now that makes sense then
