    Other than the usual stuff there is some stuff particular to the C, cant think of anything particular to the Signum

    Check:
    - Rear shocks, check for leaks and bounciness,
    - Springs, have a habit of breaking, sometimes you dont know either!
    - Some V6 CDTIs suffer a flatspot or slight vibration around 1.5k, mine did and the guy who I bought it off actually said it was a faulty injector, thing is the engine is so smooth its hardly noticeable.
    - Also check it doesnt smoke massively when booted, again quite a few suffer from this. Some black smoke is normal though when > 3k rpm or revved hard after staying at one throttle position for a while.
    - Be careful when checking the oil level also, the engine needs to be warm but leave it for 5-10 mins after stopping the engine, as the oil takes a while to drain down fully. Mine looked half empty when I checked it and I thought there was a problem, 10 minutes later all was normal.
    Cambelt has a massive interval 10y/100k or 8y/80k. But I wouldnt leave it more than 5y/60k
    Normal consumption should be 30-35 mixed driving and 40ish (possibly more) on the motorway. Check the board computer and see what they were getting.

    Vehicle : Opel Signum

    Trim : Sport

    Engine : 3.0 CDTI

    Year : 12/03

    Default

    Ask for a warranty. lol

    Take it for a test drive, preferably with the engine cold. Warm it up nicely. Once warmed up floor it on 1200rpm in 4th gear. There shouldn't be any knocking noise coming from the engine indicating a faulty injector(s). Mine does it...unfortunately

    About the black smoke...
    The V6CDTi, at least mine, seems to have moods. Like a period lol... Today it didn't smoke much, after a motorway, I mean private road, blast at 100mph+ it was even better. I see up to 100mpg sometimes lol so don't rely on the computer mate My average in 10k is 47.79mpg...can do much better if careful.
