cls55 supercharger not working
 

For about a week now it is apparrent that I am not getting any power boost from the supercharger. Called MB service and they kind of just scratched their head since no warning lights are on. Anyone know of something I can do to see what is going on before driving an hour and a half to the dealer?

usually the problem is the circulation pump for the low temperature circuit called the charge air cooler. part # 000 500 03 86 and the fuse 7.5 amp #N072581000303...was a problem for the AMG 55 supercharged cars.

Thank you for your help. I assume it is not as simple as the fuse? Is this a fairly simple (cost) effort if the the pump needs to be replaced?
