Hi,
I have a 2010 S4 B8 Avant with the Rear Sports Diff and Drive Select extras. One owner from new (prior to me acquiring the car in January 2022). Full Audi service history, 72,000 miles.
Last week on a motorway run, a ‘hum’ developed that sounded exactly like a wheel bearing had gone. It is constant so no let-up on cornering, and it sounds like it is coming from the rear passenger side.
Is there any way to check if this is a wheel bearing Vs a rear-diff issue without changing the bearings and hoping for the best?
.At around £400 per bearing with labour/parts this seems like a costly gamble.
So is an equally costly Audi diagnostic the way to go?
Any advice greatly appreciated.
Cheers
Lee
