Very peculiar problem. Took the 2004 CLK to the dealer with 2 complaints. SRS light on and hesitancy in accelerating after a long slowdown to a stop. The tach never goes to below idle, but it can take as much as 1 to 2 seconds before the gas pedal responds.

So, they corrected the SRS light, stating it was due to a loose wire in the seat back. They tested everything and could find no problem with the electronics for the hesitancy. Nor could they reproduce the problem.

I drove the car for one week. No SRS light. No hesitancy. After one week the SRS light came on and the car started to hesitate again.

Got any ideas?
