Gas pedal stuck at full throttle !

Hi people and not only that today my dashboard folding started, it also stuck on the highway my accelerator at full speed at approx. 170kmh. Is a bad feeling I tell you !! I had to reach down and pulled it up with my hand – after that was OK again. What kind of crap can this be? I slowly look back for my BMW, if this goes on. So far I was quite satisfied – I hope it doesn’t come to me any fun. l g Willy
