Been struggling w/ electrical issues for a month now. Key would turn, dashboard would light up, but when going to start it would not crank (no sound). I replaced battery, starter, front fuse box and then gave up, called an indy to diagnose. He said rather than waste the money, get a new key. It's either that or the ESP he said. My thinking is something's wrong with the radio (it said Low voltage on the screen). I got it at a junkyard from same year/model (2005 c230). Anyway, since the key unlocks the car and turns in the ignition I shouldn't waste the money, but I'm out of ideas.

 

Why do you keep opening new threads for the same problem!
Do yourself a favour take the car to a Indy that knows what he is doing because clearly you have no clue nor do you follow the advice given here!
Good luck!

 

just say I don't know, or better yet, leave it blank till someone who knows has an answer to my very specific question
good luck!

 

It is not the key. Get someone knowledgeable to assist you!!!
