    2003 E46 318Ci blue smoke

    Hi guys, I try to find the answer and I couldn't.
    I bought my Bmw few days ago and I've noticed blue smoke and smell of burned petrol from the exhaust. I think it's more petrol then oil smell.
    Can anyone share some light on it or have some contact to any Bmw specialist that could check that for me? I'm in Dublin North.
    Thanks

    It's your piston rings. Not a cheap job.
    This is my BMW. There are many like it, but this one is mine. My BMW is my best friend. It is my life. I must master it as I must master my life. My BMW, without me, is useless. Without my BMW, I am useless. I must drive my BMW true......
