Hello all. Newish to the forum and new to T6 ownership. I’m having fun so far however my van has a strange whining noise when the revs are increased (it’s not from the passenger seat!). Having looked at other threads I assume it is the aux belt or cam belt tensioner failing, but am not 100% sure so thought I’d see what others think. I can’t pinpoint it under the bonnet. It’s booked in for both to be changed next week but would be good to have some other thoughts. It’s a 150 diesel with 30k miles and coming up 4 years old. Recording of the noise attached below (hopefully if I am working the forum correctly!).
Thanks
