MellTom: No, I haven't had any 'accidents' in the winter (or summer), it can't be that.
Schnupfi: My car is never (almost never) out of commission for more than 1 day; I drive 60,000 kilometers a year. It wasn't a full stop; I didn't do that, and I have ABS.
Tito: The rims have no runout; you only feel vibrations when accelerating (during acceleration). The tires are good, they're Continental Sport Contact 2s. The wheels have been rebalanced and swapped from front to back. None of that helped.
I know it's not easy, but I suspect it might be the wheel bearing or possibly the driveshaft.
Sincerely,
Sebastiaan.
