2014 Volkswagen Passat - Service bulletin

is there a service bulletin to fix erratic shifting for a 2014 VW Passat? i have heard that there is one, but can’t find the SB number.

Here is what I would do . First look in the owners manual to verify the warranty period . Second call the selling dealer and ask if there is a service bulletin for this problem. Third if those don’t work look for the corporate contact info in your manual.
