Yes, stop driving it immediately. You can do significant damage with a badly overfilled crankcase. the obvious first step would be to drain some oil to reach the proper level.
The next question is, who changed your oil? An experienced VW shop? It's very common for inexperienced owners or incompetent shops to accidentally drain the transmission, instead of the crankcase. (The transmission drain is exposed. You have to take the belly pan off to get to the crankcase drain).
Then they "refill" with the recommended amount (closer to 5 quarts than 4) and tada! overfilled crankcase.
