Take care of it asap, I take it you are not original owner. Check with a Vw dealer to see if they have any records for a change.I have a 2007 with DSG and 107k miles. I’m pretty sure the DSG fluid and filter had never been changed. Is it a bad idea to do it at this point?
Then it was most likely skipped twice, just find a shop preferably a VW shop and take care of it. Yes you can do it yourself but you need a few spec tools and Vcds that can read the temp sensor for the trans fluid.I know the original owner and they don’t remember ever having it done.
I could probably change it myself, but I don’t want to screw it up.
