DSG fluid change, now I have a leak.

SO about a month ago I decided to tackle the DSG fluid change myself. I’m very mechanically inclined (fix airplane for a living). So I did everything by the book drained the old fluid, took pan off to gain access to internal filter, replace that, installed the pan with a brand new gasket and brand new bolts and torqued the 15 bolts 10nm. I filled it up and used a vag-com to reach the desired temp. to drain off the access. Well about a week later I kept smelling DSG fluid while sitting at a stop for awhile, so I decided to crawl underneath and check for leaks, sure enough it was leaking right between the pan and the transmission, right past the new gasket, so I thought I must have not done something right, so I snugged the bolts up more to see if its going to stop, sure enough it kept seeping past the gasket still. Well I decided to get another gasket and redo the whole job. So I did everything per the manual again 10nm for the bolts blah blah, well another week later and I smelled the DSG fluid again, now mind you I used alcohol and a clean rag to clean up any spills that may have gotten around the DSG. I crawled under the car again and sure enough its still leaking so I snugged the bolts down some more and it’s still seeping between the pan and the transmission. So I’m at a loss, do I take it to the dealer (my dealer in town is horrible so the closest other one is an hr away) and let them mess with it, or do I install another gasket using another new gasket AND RTV this time. I’m just not sure what to do.
