Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 7 months ago

this is not a common issue, the things i would check are

  1. how many keys on the key ring
  2. does the ignition switch feel nice and solid when turning the key, we have had issues with the ignition switch
  3. loose connection at the cluster
  4. communication issue within the car

this will be a hard issue to tell what is wrong but those are things to have checked.

if the dash cut out then there will be codes.

do not remove the battery cable so we do not lose the codes.

your best bet is to have it scanned with a mercedes capable scan tool

hope this helps.

Lou
