Hi Anton,

You didn't confirm if the van has been serviced recently? Or any other work, in tge absence of any specific details, photos etc it's pretty hard to begin.

possible Crank case seal - very common both end of the Block
DSG Gearbox leak
DSG drain plug(s)
Sump bolt
Oil filter - usually wrong torq allow some blow by
Oil tracking from oil loss in another another part of the engine

If there is a lot of oil I would suggest you get it checked out ASAP and font drive it on long journeys.

any garage shoukd be able to put tge van on a lift and have a good look to identify to most likely culprit.

Thanks a lot for Your reply. My mechanic found that rust has caused a leak in a ca. 8cm Ø round plate in the gearbox (se picture)

We feel for you! It was an issue that we had in 2022 see above!
Took the agent ages to sort out( needed a replacement front cover for the engine) and we were without a camper for months with no offer of a loan vehicle.
It is obvious that the T6 engine is prone to leaks.
