Very interesting Acta. this sounds related to my issues. my 2020 glc300 gets driven very rarely (long story, only 8k miles). i get emails periodically "critical battery". car always starts and charges and is good for months before getting the same message. note: i turned off some features that monitor and send info out and that extends the time interval.
recently, i get a bunch of "inoperable" messages (ESP and others) periodically, but i continue driving and next time i start the car, no messages. now, after a critical batter alert, i see my first check engine light. i checked codes with a foxwell scanner with mb software and saw p0300 misfire on cylinders 1 and 3. also, a lot of "faults" in a car specific scan (me motor electronics fault 10, vgs transmission control fault 3, esp fault 1, etc). this must be related to the battery.
i haven't reset the codes since the car was driven and the battery got its charge back.
i haven't noticed any driving issues since i got the p0300 code. maybe worth noting: i replaced the engine air filter a few months ago and believe i reconnected everything properly.
any thoughts? (note: bought the car in 2019 so the warranty is up).
thanks in advance,
Scott

thanks for the suggestion. I reset the tire pressure and drove 25 miles with no check engine or "inoperable" messages. When I put it in reverse to park, the messages popped up (park assist, parking brake). Later, i drove home with no messages.
Do you think this is related to the discharging of the battery so many times? Someone linked the CEL (misfires) to electrical problems. Note: the battery always started the car easily, even after getting "critical battery" messages.

Issue
I got the same message on my 2022 EQS AMG and after a week in the shop it was determined to be a problem with my wheel speed sensor. Its been almost 8 months and had not seen the issue reappear.. The solution was sent by a mercedes engineer to my local dealership tech to perform..
