It's not necessarily mercedes, it's the dealership making decisions at this point from what you've described. If there is another dealership nearby try them and see if they are any more capable of figuring out exactly what is wrong and if it's covered by warranty.
if the supercharger was not factory installed by mercedes (or AMG), then it's another story. Your really on your own, and mercedes likely won't warranty anything.
In the U.S. Mfg are not required to warranty any aftermarket mods, or warranty against damage from the use of them. the Magnesun-Morrison (sp?) act does require that the mfg must allow the use of aftermarket parts meeting factory spec's for required vehicle maintenance as defined in the warranty requirements. E.G. it allows you to use non factory oil filters, fuel filters, air filters, oils, fluids etc. w/o worrying about warranty as long as the aftermarket parts meet the spec's called out by the mfg.
MM protection doesn't (contrary to what lots of folks believe) apply to other mods, e.g. chips, superchargers, headers etc. In this case YOU need to PROVE the aftermarket additions did NOT cause the failure! And the Mfg is free to deny and/or void your warranty for use of such accessories. presently Ford, GM, and Chrysler are actively voiding power train warranties on diesels if any aftermarket tuner has ever been installed. Wouldn't be suprised if Mercedes does the same.
