    Please help I have a 2004 X5 3.0d My turbo recently blew which of cause has also caused untold problems. One question I had was "can we maintain, check our turbo's" As when I asked our BMW dealer i was told they wait for them to break and then they replace it. When I am footing the bill it is a bit hard to chew. Please help me on this one

    Many Thanks

    Juliette

    If the vehicle is serviced regularly and the oil level is checked then the turbo going prematurely is a issue of BMW. They shouldn't fail prematurely. You can remove the Turbo pipe and wobble the impeller to check for excessive play and look to see if there is any scoring in the housing from the impeller rubbing.

    its not an 'easy; thing to check unless you are familiar with car engine to be honest Juliette but you can look for tell tale signs...

    one of them being excessive black smoke out of the exhaust on acceleration (it could also be other causes, but it is relevant)

    as Ronnie says, for an 04 car it is unusual unless it has very high miles.

    To preserve you new turbo, DONT thrash the car until it is warmed up (or wait till 5 or 10 minutes of driving as a benchmark average!)

    and when you return home with the car after a drive, leave the engine running for 30 seconds or a minute..
    This helps oil circulation for the turbo and allows it to cool down. Excessive heat is a big killer of turbos

    Thank so much for your replys. One more question. Do you know if an auxilary fan not working would contribute to the turbo going ?

    Not directly. You would have to get the car really hot and keep driving it with it overheating(and low on oil), but something else would go well before the turbo

    I agree with Ronnie.

    Its more likely that this would just cause overheating in heavy traffic in hot weather.
    not really a turbo killer as turbos operate at a very high temperature anyway
