The sump guard has taken a lot of hits and scrapes over the years, even more so since I’ve lowered the RS6. Thankfully one of the small cracks in the guard revealed that there was an oil leak.
Pulling the sump guard off revealed, obviously, a lot of oil. Everywhere. I cleaned up the sump, sway bar and surrounding areas and left the guard off.
After a couple of days of easy driving to and from work I put the car back up on the hoist and this is what it looks like:
It appears to be coming from the back of the sump gasket. There is no oil above the gasket so it’s fairly safe to assume that it’s not coming from anything higher. It’s booked in next week to get this looked at.
