Suspected Oil leak on the Q7

Weird one this, the cars barely 3 years old done just over 50k.

But last week I noticed alot of oil marks on the drive, initially I put it down to the Mondeo leaking clutch fluid. Just to make sure I went under the bonnet of the Q7, I was shocked when I saw oil over the engine.

It was as if a mini explosion had taken place, there was oil every where!!!! including the radiator fan. Took it to my cousin's garage in east london, they kept it for a couple of days but could not find a drip, leak or anything anywhere.

Kind of concernded as to where the oil came from, but at the same time kind of relieved it aint leaking, but I'm keeping a close eye on it.

Some have suggested it may have been that the dip stick was not sealed closed and the oil splurted out, would explain the explosion likeness.

I'm in the southwest next week so if the leak persists might have to get a Audi dealer in the southwest to have a look.
