Driving '06 R53 (JCW), (rain, nighttime) a while back on the highway, I hit some good potholes. Managed to get an egg on my driver's front run flat. Now when I hit a decent bump, I get 3 lights that turn on: tire pressure, DSC and EML. The car goes into "limp mode" too (very little, if any acceleration). I've tried the tire pressure button as well. Everything will go back to normal with a "flick" off/on of the ignition key. Any help?

 

sounds like a damaged or loose wheel speed sensor sending bad data to the ABS system

 

Thanks. I'll check that out. Although the ABS light doesn't come on.
