i have a 2001 c320 and my front speakers produce costant static from them. My radio turns on but no music comes out, all i get is loud thumps from my front speakers. When the radio is off i can hear some soft static. What can i do to fix this and will this constant static drain my battery?

 

do you have any problem with charging system or alternator? bad diodes can cause this.

have the radio checked by good technician.

 

There is no known problems with charging or the alternator. Do i have to take my car in to mercedes to be checked? So far my battery seems to be good but can this be a problem where it will drain my battery?
