    Default Passat judder/missfire @3000 rpm

    Hi guys. Hopefully someone will make an educated guess regarding my Passat, 1.9 tdi, BKP engine.

    I'm experiecing judders while driving at about 3000 rpm, mostly in 4th,5th and 6th gear. Below and above that rpm there is no problem.
    Now, the things i've done to try and remedy this:
    -checked vaccum lines and pump pressure - ok
    - recently changed turbo
    - changed gaskets in tandem pump
    - changed fuel and air filter
    -checked fuel tank pump for obstruction - ok
    - egr valve cleaned and working
    - changed air intake flap
    -changed MAF with new one
    - also i've got NO fault codes

    Even a guess would work, as I'm out of ideas.

    Check the camshafts, especially on the intake side. Worn out camshafts are a plague in b-series engines

    I agree with you, rumor states millions of results on INFERIOR websites, but unable to confirm
