Hi, I was servicing my Allroad last night. When I removed the under tray, I noticed oil around the sump. It looked as though it could be coming from the sump gasket. Is this a common problem? The car has 134k miles on it. The car doesn't use oil and is checked every couple of weeks. I can't remember the last time I had to top it up to be honest so it's not losing a considable amount . I also haven't noticed any oil under the car. It's due for a cambelt in the next couple of weeks so I didn't bother putting £60 worth of oil and filter into it in case the garage that's doing the timimg belt decide that the sump or other seals need to be replaced.
