    Default V6 CDTi Engine Shudder

    I would welcome any advice re: 3.0V6 CDTi with 30,000 miles. 55 Plate. Between 1400 and 2000 revs in any gear the engine feels as if is is missing it gives the effect of driving over cobbles. I have had the car 2 months it has spent 6 days in VX dealers they say they cannot find anything wrong and suggest I change my driving style to avoid that rev band. No codes showing up and after talking to VX they say it may be a characteristic of the vehicle. They have updated software on EMS and replaced a sensor which produced small improvement for a short time but now as bad as ever. I have a three year dealeship warranty but that is not much good if they say there is nothing wrong. HELP!!!!!!

    After hours of studying various comments on the Forum, I have now carried out the pedal test. I am getting code 0460. Does this make sense to anyone with the symtoms that my car is showing?

    Many Thanks

    You need to consult TIS to see what parts are affected by that fault code
    Sounds like the low pressure fuel pump is not receiving the right values
    When was the fuel filter last changed (recommended every 10K miles / 6 months, but the service schedule is 20K miles / 2 years)

    34K miles is at least 2/3rd of the cars life!
    There is NO way I would have put up with it for that long...
    What age was the car when you first reported it at 44K miles, and where to?

    A blocked SCV will fail completely within about 5K miles, so I doubt it is that

    That suggests it is a faulty solenoid, as the car will run on the other five

    You really need to take the car to a diesel specialist, with experience of the Y30DT engine
    I will bet they can diagnose it within 30 minutes
