  • RPM judder and black smoke........again.

    Hello,

    I have replaced the fuel pressure regulator about 2 years ago (2.0 CDTi), yet a few days ago my car again developed severe RPM judder (+/- 400 RPM at idle, sometimes hard to start and maintain idle) and lots of black smoke. I am assuming that it is again the fuel pressure regulator.

    I will change it no doubt but what do you guys think can cause it to fail just about 2 years later or 30 000 KM driven? The part is pretty expensive to be replaced every year or so.

    what did the old one look like when you removed it.?
    I've known pressure regulators go but not 2 in 2 years .
    Not unless it's picking up dirt .
