Hi all Sorry if this has been covered before but can't find it if so... My RS3 is coming up to 10k miles and going in for an oil service plus other bits later this week. I have twice in last week had a really odd sounding noise from the rear, sounds like a drive shaft knocking or loudly clicking. It increases or decreases with rolling speed and definitely isn't tyre or brake related. It's so come and gone so intermittent. Has anyone else experienced or heard about this please? Thanks a lot.
