    Smile cdti 150 turbo whistle

    Hi All,

    Anyone have any experience with their turbo whistling really loudly? i have had all the pipes checked to make sure they are all tightly fitted and not leaking and the sound is definetely coming from the turbo unit itself? is this an impending sign of failure of the shaft bearings etc. the car itself is not down on power and is using no oil.

    any advice /experience here would be welcomed.

    if its new turbo time any good reputable places to source one?

    the engines done 108,000 miles

    thanks in advance

    Andy

    The turbo on mine is very noticeable, and as far as I can remember it always has been. Mine's covered 36,000 miles.

    Providing it's still boosting okay I wouldn't be too worried. We have a fleet of (other manufacturer's) cars at work - some of them have loud turbo's, some don't. And they are all identical.

    Mine has done 110k now with a remap to 175bhp. Sounds fine. Had it for 25k. I like hearing it!!!

    yeah, I've had passengers say "is it meant to make that noise?" Luckily I had 3 or 4 CDTi Astras as company cars before i got my vec and they all did it from new so I don't think its anything to worry about.
