2004 s 430 4 matic 100 000 mile service
 

hi
2004 s class 4 matic just passed 100 000. now its 104000 mile on the screen it says 4000 mile passed service all the time. yesterday suddenly srs light came up and navigation doesnt working color of the climate contorl became lighter than normal. and finally radio doesnt work. when i try to turn on the radio loud noise comes from right speaker. what do you guys recommend.

do you do proper preventive maintenance intervals? best is to send it for a star diagnosis check up to find out the fault codes.
