    Morning guys. My 2006 2.0TDI140 Sharan has recently started making a sharp whistle from around the turbo area during acceleration. Normally I'd suspect an air leak as it sounds a bit like that, but it's only for around 500 rpm - once above that the noise is largely gone.

    It'll do this in neutral too. I was underneath it but couldn't pin down the location of the noise. Above it, it sounds like its coming from the back of the engine. I've checked the lower boost hoses for splits as best I could in-situ but found nothing. They are covered in oil though so I guess that isn't a good thing as far as the o-rings are concerned.

    Would the limited rev-range characteristics of the noise suggest imminent turbo failure (230,000 miles...), or could it be an o-ring issue that somehow self-seals with more RPM?

    Any help gratefully received - its life or death time for the old bus...

    Can you get the turbo air inlet pipe off and see the compressor shaft end, and compressor wheel, get it between your fingertips and see how much radial lift there is on the shaft, you might find there is a lot of lift and the compressor wheel can touch the casing sides, or you might see the compressor wheel blades are worn on the edges. In either case the turbo is toast. That a fair old mileage on original turbo though. If it was an o ring leak I'd expect it to get worse as turbo boost increases.

    I don't think I can get near it thanks to where it's at, but thats what I'm fearing... Will cost more than the bus is worth to have the turbo replaced I'd imagine.
