    Smokey exhaust on a 2010 BMW 120i

    Asked by Graham

    My 2010 BMW 120i coupe uses a lot of oil. It idles perfectly, runs without missing, has power, but smoke comes from the exhaust when I decelerate and when sitting at lights, or stationary, but not when I am accelerating. Any ideas please?

    The engine is probably worn and needs honing and new rings.
