Have you guys had the dealer techs look into what Coyote said here?
I've read about this being a common problem on the MB forums also.
When the supercharger gets to a certain temp that is too hot, it will not engage until it cools back down.
So say your sitting at a stop light, the supercharger heats up a little from lack of coolant flow, then you take off and there is no power due to the supercharger not working.
Then after driving down the road, wind blowing through the intercooler, cools off the supercharger just enough for it to work again.
