ABS light on after launching with ESP off???
I launched my E55 tonight at a light with the ESP off and now the ABS light is illuminated. Is this a common problem?

yes this is common, the esp is still partially on even with the switch on. You have to put the car into dyno mode to completely disable the esp. search "dyno mode" and it will tell you how to do it

Take it to the dealer and have your ABC pump checked. I had the error as others have had and it can either be the pump or reservoir. FYI Pump is covered under a 10 warranty, reservoir is not.

Thanks for the quick responses. The malfunctions all went away after starting the car this morning. Everything seems to be working just fine again other than this supercharger squeak..is it slipping? Should I start looking for a new clutch pack?

THe squeak you hear is the SC clutch engaging. If you can live with the squeak it's not an issue but most have found sooner or later the ball bearings break loose inside the pulley housing and rattle around which then obviously requires a new SC pulley clutch pack. If you are not under warranty then there are two routes to go at this point. New pack or just replace the bearing. I was under warranty when mine went so it was a new SC pulley clutch pak for me.
