    Vehicle : Opel Vectra C

    Trim : Estate F35, Elegance

    Engine : Y22DTR

    Year : 2004

    Default 2.2 dti fragile injection pump

    Just copy and paste from a UK site:

    "A number of vauxhalls and Saabs from late 2002 use a VP44 PSG16 injection pump. This pump is very fragile and VERY costly to replace (currently it is not repairable) because of this we DO NOT supply any tuning device to increase power of an engine fitted with this pump."

    If it is true, is a bad news for me and my 2004 2.2 dti!
    Do you already know this?

    They're not really fragile, they just don't like poor quality fuel. I know of 4 VP44's that have failed REALLY early, and they all ran on only Asda diesel. 2 were Vauxhalls, one was a Nissan (2.2 Almera) and a Rover 45 (2.0 L-series).

    The VP44 was a really hi-tech piece of kit for the time - only some of the more recent common rail systems are doing stuff the VP44 could do. 1600BAR injection pressure, the ability to do minute injection before the main injection to reduce knock during warmup, etc, etc. Early commonrail systems were actually a step backwards compared to the VP44. Of course, being really high pressure and what-not means there's some really fine tolerances in the guts of the pump - low lube fuel or dirt will kill the pump stone dead.

    So, yes, feed it **** fuel and you'll be looking £800 for a rebuild of the pump. Give it decent fuel and maybe a fuel additive and you should be fine.

    I use Miller's Power Sport 4 in my 2.0DTi and it's been fine so far. 58k and going strong.

    I ran mine on 100% oil, straight from the bottle! Strangly enough the pump died after about 6 months... I got her fixed up though and then moved her on... Still sad that I don't know where she went

    Just bough ****** big bottles of cooking oil from the supper market and poured them in neet. Can't say for sure if it was the oil or not that did it as I had stopped using it about a month before the pump died and many of these pumps died at about the 60K mark on the Vectra Bs (Mine was a Vectra-B). I think the smell was much nicer than diesel, though it did make me feel hungry alot.

    I used Miller's Power Sport too in my old Vec b 2.2dti & had it remapped with no issues at all.

    The motor is now in the north east with over 120k miles on it, & still going strong.
