    Oh dear. Oh dear oh dear.

    I think the turbo on my much maligned Saab 9-3 1.8t is going the way of the dodo.

    A few days ago, a whine that sounded like a lowish-pitched siren started sounding when the car was cold. It'd disappear after warming up. As of this evening and after a bit of a run, the thing is now somewhat louder and knackered-bearing sounding.

    The engine sounds like the usual GM bag-of-spanners-in-a-washing-machine-falling-down-the-side-of-a-mountain when revved when stationary as it always does, and has a veeeery slight hint of tensioner bearing whine (see first video below).

    Under load however, it's smelling oily and making a non-engine speed dependant knackered-bearing sound that fades when the accelerator is released (independently of revs, second video).

    Video 1, stationary:

    Video 2, under load and in gear:

    Does the above describe what I think is a buggered turbot?

    It could do, the second video sounds more like a split boost pipe/air hose. check any history you have and see if the timing and aux belts and related tensioners have been replaced aswell as the waterpump. If not get them done.

    Looked under the bonnet - couldn't see anything obvious. I did change the throttle body last week and thought the hose might have popped off that, but it's securely fixed.

    Hmmm.

    Personally I'd be more concerned - about the turbo - if you had a lot of smoke coming from the exhaust, tbh it doesn't sound like turbo failure to me.

    This, just because you can't see a boost leak doesn't mean there isn't one. Plenty of little hoses dotted around which could be the culprit

    Does sound like a leak, a leak on the exhaust side can sound exactly the same too.
    Equally, just because it isn't smoking doesn't mean it isn't going to. Both the turbos I've had fail have whined and then quickly progressed to complete failure. One of them took a day, the other one took seconds.

    Okay, cheers guys. :)

    I'll have a damn good look at it this evening. A simple blown hose or line would be much nicer than having to replace the turbo. I'll keep the thread updated.

    Turbot is very unhappy.

    Lots of exhaust smoke with the engine running. Loads in fact. Couldn't see it last night. Testicles.

    Compressor wheel wobbles quite nicely. Time to do a bit of shopping...

    Is your engine one that could be affected by the sludging issues? If so have you had the sump dropped yet to check?

    No, it's not a sludge-affected engine. Although I don't see why it wouldn't make an exception for me!

    Oh dear.

    It seems that it's cheaper to buy a brand new Garrett TD04-14T Aero turbo upgrade kit and have the car mapped to it than to buy the original turbo meant for the car. I'm not sure what to do. :D

    Well I've exhausted my entire vague knowledge of the new fangled Saabs with my one query lol

    What happened to Saab? All the oldies tell me that in the 70s and 80s they were the must own cars.
