Hi my turbo has recently gone on my 2003 525d e39 the car itself has only coverd 107,000 miles full bmw service history and this just seems to premature, can any one tell me if these are prone on these and why it might have gone, as i always let the turbo wine down before turning engine off as well, and can anyone tell me where i can get one for the best price, either new or reconditioned.

Thanks

Jason
