    2011 CDI, around 9000 miles on the clock...

    The car has been jolting a little, like when a petrol car has a slight misfire and then clears itself, then a few weeks ago it went into limp mode, no lights on the dash, just the normal not revving above 3000rpm.

    I have attached Das, and there is a fault in the N3/9 CDI Control Unit,

    P2306 Sensor supply voltage is too high or too low Stored
    P0190 The signal from the b4/6 (Rail pressure sensor) is implausible or no signal.

    I have run the tests, the voltage is 4.97 (range 4.6-5.2) so that's ok....

    I have done the offset test and it says it all ok.

    Cleared the codes, drive it and they come back.....


    Im in Essex if anyone has any ideas...
