The transmission has always ground going into reverse. The dealership told me it was normal for the Jetta's. While driving, I will put it into 1st gear and start moving, and then it will either get "stuck" into first or second gear, I can take it out of gear but cannot engage another gear. When this happens, you can smell the clutch burning. Took it into the dealership and they assured me my transmission and clutch were fine. Doesn't happen all the time, only about once a month and it happens in varying weather conditions. No two times were the conditions the same. I have not changed my driving, I am not hard on my vehicles. My 2014 fiesta st had the stock transmission and clutch until I sold it in 2019, never slipped or ground into gears, along with my 6 other manual transmission vehicles I've owned. I feel like Volkswagen just doesn't want to fix their terrible transmissions and clutches and tries to blame it on user error.
