Hello RS246 members,

My 2020 RS6 C8 has just gone in for its first service and have had the displeasure of finding out that there is an oil leak on the rear differential and will likely need to be fully replaced once the service centre have completed their full inspection…
This will be under warranty, however it’s quite concerning as the car is only a year old and done 15,000 miles.
Has anyone had similar problems?

I had the same on my 70 reg RS6 as well and it took 3 weeks for the bits from Germany to arrive. What's more annoying is that mine has had a periodic misfire at idle when warm that the dealer are now on their fourth attempt to solve, wish I'd stuck with my C7 performance. Build quality on these C8s isn't what it used to be in my experience sadly.
