Hello, so the battery on my c class w205 died and had to do a jump start. Now my dash is not working at all. The speedometer is stuck.Even when i turn off the car I get this message. What do I need to do>

 

Check all your fuses and if that doesn't help, you'll need to take it to a dealer so they can run a diagnostic on it.

 

now the speedometer lighting does not work.

 

“Plays taps”. She’s dead Jim.

 

Honestly, if your fuses are good, you'll need to see what errors there are (if any), so this alone will probably require a trip to the dealer. You can also do some web research on "Mercedes Benz instrument cluster issues after jump starting" and see what that yields. But I don't think there's anyone that can help you unless they're a technician with access to the vehicle, or someone who has experienced the same thing and posted about it online.
