HI everyone i'm new on here and i just wanted to know if anyone knows about the mercedes cls500 i don't know why my cls500 keeps dying after i park my car for a couple of days. The battery is new and so is the alternator. I brought it to the mercedes benz dealership and they don't know what the problem is. my car only has 40,000 miles on it. Does anyone know what could be the problem? Thank you!

 

you have a draw someplace...if its under factory warranty..tell them to fix it...you have to understamd that this could take a few weeks to get to the bottom of your problem..

 

The battery in my '06 fails to hold a charge and the dealer says it's the "battery control unit" priced over $500. They replaced both batteries but that didn't help. Good luck.
