I have a 2010 VW CC with the 2.0T TSI engine and the DSG transmission.
I did the DSG fluid change at 40,000 miles as specified by VAG. New fluid, filter, o-ring for the filter cap. Around 7,000 miles later, it began leaking from the filter cap.
So I changed the fluid again. Again, 8,000 miles after the fluid change it is leaking from the filter cap again. I made sure on the second change that the filter cap threads were clean of any debris and made sure it was on stout. Pulled the battery out to tighten up the filter cap and it was on securely, but I was able to snug it up a little further.
Anyone aware of what I might be doing wrong. I have no idea on how much fluid I may have lost, but driving it this way but it doesn't seem to have any issues shifting. How should I refill to make sure I have the correct amount of fluid in the trans without draining everything and refilling AGAIN?
