    Hello.
    I have problem with my Passat. Is jumping engine idling speed from about 500 rpm to 1000 rpm when engine is could. I was cheking injektors, diesel pump and rail system. Everything is ok. No trobel codes. Where can be a problem?

    Vacuum leaks? Fuel delivery pressure? Dirty fuel filter? Many things could cause this issue that don't throw error codes, mostly mechanical issues.
