Classic example of a CPS failure. It has happened to me on two cars an e430
and an slk320. The problem will go away when the car cools down and reappear
when it is hot.
The CPS is located just above the bell housing on the rear of the engine on
the drivers side (down between the engine and the fire wall). You should be
able to see it if you look down over and past the brake master cylinder.
There will be a wire lead connected to it.
The bolt that attaches it is torks. If you have the right tools, it should
take less than an hour to replace it.
I hate torks :(

Torx or even a specific allen wrench size too I hear. Anyone know the size
of torx/allen I'd need?
