    Can anyone give me some advice please?

    Hi Guys

    I am a new member and I have a 53 plate 1.7 Cdti Astra. The car runs great, no start up smoke and burns no oil. It has done 103k with a full service history.
    The problem I have is under acceleration you get a lot of black/grey smoke. I have put some injector cleaner in and given it a good run up the motorway. I thought it had helped but I think the blow out just cleaned the system out as It's back again now. Does anyone have any ideas? It doesn't seem to do it if you rev it when it's stood still.

    Cheers

    Darren

    Firstly, check the air cleaner and make sure there is no obstrution in the air intake pipework. Other problems may be overfuelling of the injectors, a bunged up EGR/CAT or low boost pressure caused by the turbo not supplying enough air for the fuel injected.
