HI,

Ok, are you using an original key or replacement key?

Does it start and run at this point, or is it to a no start state?

Starts and runs is original key
Mercedes Mechanic: Eric, Automotive Repair Shop Manager replied 1 year ago

HI,

Ok, these are error codes for the immobilizer and start/stop control systems. This may be an error registered for the key, the antenna ring, start/stop control module or immobilizer control module.

Unfortunately this absolutely REQUIRES a Mercedes STAR scan tool in order to diagnose.

While it is still starting fine, at some point if not diagnosed and corrected, it will leave you stranded with a no start condition.

Most of the time it is the immobilizer control module, but being that this is quite expensive, I would have it properly diagnosed before replacing.
