turbo

[jonnyloppy]

when cold the turbo on my 07 tdi 140 sounds a little like a police siren..fine when its warmed up . now somebody on another forum reckons it means the oil wants changing and / or the bearings are on their way out ?
well ive driven 3 of these cars now and they`ve all done it.
your thoughts please...just to ease my mind .......:confused:

It's fine. The noise is air not bearings.
