best bet is to wipe down all messed up oil leak with a rag first......... then use some carb cleaner spray or brake cleaner (whatever handy)to clean the rest off superficial areas such as ur dsg area and engine oil pan area (things that are covered in it immediately to ur eye).... and instead of waiting weeks to come back to it.. go under ur car with a torch while the engine is running or has just run and see where it is dripping or streaming to..

you might even need to clean it all off and immediately do a lap of the block and go under.. but usually giving it a an hour or so of standing then check again is a good way to see where it dripping or u can find the route of the oil.. also check above the area of ur oil pan to see if its leaking down from the engine bay as it might just be ur oil pan.

unfortunately after driving ur car with a leak the oil is literally going to go everywhere and hard to know exactly where its dripping from.... something as insignicant as a failed oil pan gasket can cause a major leak (common issue)... only takes 1 corner or a couple of screws dripping to look like a major leak
