mercedesc207

Hello I have a 2011 Mercedes E Class coupe
The car won't crack over to start
the dash lights turn on all fuses are okay
interior heating doesn't turn on
sometimes buttons on steering wheel don't work also the radio controls and seats
gearbox used to show on the dash screen if its in park still wouldn't start then
shows srs airbags on dash

don't know where to start to try and fix this problem or what is causing it not to start and help would be appreciated

Welcome, best to post this in the C207 forum which is for your car at https://mbworld.org/forums/e-class-c...brio-a207-141/

At first I thought it could be the inductor ring around the ignition as this has been known on the range, but some symptoms don't fit that. I'd start with the basics and check all of the earthing points for the battery and engine.
