    Hi.

    Sorry, know next to nothing about cars so might struggle to articulate this.

    Got an 09 plate e220 Cdi. Fine most of the time, drives well but on hard acceleration I get a huge cloud of black smoke. Accelerates fine otherwise. Worried it might be something nasty. Any help/advice greatly appreciated.

    Thank you.

    Welcome.

    If the car hasn't been driven much it may clear up, but try adding some injector cleaner. I like Millers brand, it really seems to work.

    Thanks dieselman. Never heard of injector cleaner. Do you just add it to your fuel?

    Cheers

    I found Shell v power or ~BP ultimate to be effective too

    Air filter may need changing.

    Thanks all.

    Italian tune up today seems to have cleared it for now.

    Still worth giving it a dose of Millers. A bottle will treat several tank fulls.

    Many recommend that injectors be changed every 60K.
    They are a heavy-wear service item.
    I'm just about to change mine - something I shoulda done when I got it 18 months ago at 85K ... when it was already smoking a fair bit.
    But I wanted to eliminate all other possible causes first.
    When it gets really bad, the soot'll start coking up your lamda sensor - which'll sometimes put it in limp mode.

    Thanks Lord. What's the damage for changing injectors?
