I know of many who are flat towing newer Volkswagens that have both 5 and 6 speed manual transmissions and front-wheel-drive.
We know that Volkswagen has never approved of any
of their cars to be flat-towed behind a motorhome but as said, many are doing so if the car is equipped with a manual transmission (with clutch pedal, not DSG) and front-wheel-drive.
I've posted this video several times on the forum of a guy doing so with a 2017 Jetta ...GO HERE
(don't let the "damage done!" splash screen fool you as you have to go through the entire video for the explanation)
