Welp, I hate to have to take back what I said about videos this week, but my car is about to go in for service and if forum posts are any indication, I may not get it back for a while. My adaptive suspension has occasionally thrown errors since days after I picked up the car, but yesterday, with 1000 miles left on my road trip, it stopped working entirely, which turned the car into a floaty + sloppy mess. The car rightfully limits your top speed in this mode, because on anything but perfect roads it is dangerous to drive.
(and no, this has nothing to do with any modification to the car, period. this error happened from day one, but increased in frequency until ultimately failing during my long road trip over the weekend.)
