Best Answer

1. Dead battery 2. CPS is bad and needs to be replaced 3. Bad starter motor

Hard to tell unless you can give more details, does it make a sound when you try and turn it over? A classic dead battery sound on Mercedes is a click noise when you try and start it, sometimes it confuses people and they think the starter motor is bad but that's not the case.

I had a similar problem and it turned out that the grounding strap on the starter motor just disintegrated.
