Hi all, I have a 200tdi auto that has 173000km on it, well serviced,and I have a 'whirring' noise that rises and falls with engine revs, and has got much worse over the lasy week, sounds like it comes from around the bulkhead area, I'm hoping that it's not the auto trans, which is shifting as normal and behaving itself. The trans filter and fluid was changed late last year and has done about 8000k's since then. The oil level is correct and the the oil looks good.
Anyone got ant ideas from a poor description of sound?

Cheers, Jack
