				Question for Jason.... or anyone else who may know

				As title says a question for you Jase or Dom...or if anyone else has any input 
 
 
The x is playing up a little and cranks/turns over for a lot longer than normal before starting.Once started it will run ok but doesn't seem to have full power and i keep getting the   'Fuel injection system'   warning flashing up on the dash.
I have scanned it and the warning/code i keep getting is    ' Plausibility rail-pressure volume regulated'
Can you shed any light on this for me fella as the x is apita at the mo  
 
 
I was thinking injectors or maybe a sensor as it doesn't seem permanent (it cut out and died the other day but then re started and ran fine 

 )but to be honest i have no idea at the moment  
 
  
Any help is appreciated

				If it's a Diesel, is it the Common Rail Fuel pressure perhaps?  There's a sensor on it somewhere even though the fault code almost sounds like a bad Google translation 
 
Could it also be low fuel pressure caused by a clogged fuel filter?  I've had a quick scan on the Web and it could indicate a fuel pressure regulator error.  Item 2 in the diagram - used my 2005 as the basis for getting the drawing.

				Thanks for the reply fella.I have just changed my signature.....i didn't relize that i hadn't put 3.0d  
 
   
 
Yeah i have to agree the warning message is a strange one.I have also posted on xoutpost as there are a few bmw techs on there that know there stuff but being a diesel i'm not expecting too many answers  

 .
One guy says that the Most common issue with that error code is a faulty rail sensor pressure switch.Which is number 3 on that link but at £180 i want to check over the engine first to make sure i haven't disturbed anything when doing my other jobs 
 
 
I love my x but damn these beasts can be frustrating with all the sensors etc.............i sometimes whish i still had my little (original) mini's .......when they broke down you could throw a spanner at them.........or just carry them home  
 
 
Ohh well the joys of expensive toys ehh!!  well expensive ish

				Oh I hear you loud and clear on the sensor issues, and things were sooooo much easier when as you say you could fix it in 5 minutes!!  These days I suspect a lot of us just open the boennet, take one look at what's there and shut the bonnet quietly - then yell NURSE!!  I think a short engine for my old Cavalier cost less than this sensor and the SatNav Discs combined  
 
 
I could do with changing the breather valve and air filter on ours but I could do with a manual to see exactly what to take off.  I have the technical ability and probably the right tools as I used to do all my own servicing.  Can't do things like the brakes as a spinal injury stops me working at low levels - fine on a lift though.  No one seems to have written a Diesel manual though - which is why this group is so important and useful.  We need a pdf area with all the how to guides written up
