    Hi can anyone please help
    I have smoke coming out from under my bonnet on the passenger side when I start my car and run for a few mins
    This seems to stop once I've driven for a bit
    Many thanks

    Hiya

    sounds like the FBH, will come on below 7c, u should see a small exhaust by ur passenger side front wheel

    it would of course also be best to lift ur bonnet to ensure 100% it’s that , then start the engine and see where it’s coming from

    hope that helps

    ur very welcome , apologies, FBH is fuel burner heater , ur arrow is the FBH exhaust

    basically heats ur engine up quicker when it’s below 7c and therefore get the cabin warmer quicker

    some more info for u
