Hello. I own 2013 Passat TDI with 93k miles. Having issues with acceleration. In park, it does not go past 25krpm's. In drive, it struggles (boggs down) going through gears and as it is advancing gears, there is a ticker sound . After driving for about 3 to 4 miles it drives smooth like nothing wrong. But in park, still don't go past 25krpm's. Thanks for looking and any ideas, suggestions, comments. Per previous suggestions i will be checking the fuel filter and probably ordering the VCDS or VAGCOM diagmostics software, not sure if its same thing.
