I so unfortunately i was right steve OEM from VW - i was quoted wait for it - £400 I got a reconditioned unit for £150.
There was fluid on the subframe underneath the gaitor
Will the fluid damage the paint on the alloys?? Might be worth checking.
Fook sorry to hear that mate mines currently having 2 new front wheel bearings the noise was doing my nut in only coming from one of them but thought I may aswell do the pair. Hope you get it sorted and doesnt cost a fortune.
