Not sure if anyone else has had this issue yet, but I just got my EQS450+ 4 days ago and it charged great the first 2 times using my ChargePoint home flex charger. However, during the third charge, I got an error message from MMe app saying that there was an issue charging. I have tried several different ChargePoint public chargers which are not working as I keep getting a blinking orange light on the charge socket but no error messages otherwise. The only charger that has worked has been Electrify America, which is 30 miles away from me and inconvenient to charge at during the day due to traffic. I plan on going into the service dept tomorrow with this issue but has anyone else had this experience?

Check you are pushing in the connector all the way as far as it will go. Make sure that the charging cable is not almost trying to pull itself away if the the cable is too short. It sounds like the car is trying to make a connection but can't for some reason, or else maybe charging is happening but that is not obvious. Be interesting to hear if Mercedes find the solution.

I have problems with the 7.3KW charger (EQV - starts and stops all the time). After two visits to the dealer we have now established that its the cable. Initially they tried to change the settings so this is something that you may want to try at these charging points. It did not work with my car. Slow charging (2.3KW) and fast charging no problem at all. The dealer ordered the cable last month and hopefully we will have it next week (Initially I was told that it will arrive in November 2022 - yes this is not a joke - but the issue was "escalated"). I will update after trying the new cable.

It ended up being the onboard charging computer that went bad. Took a few days to change out but has been working great with ask chargers since

These are annoying hiccups, but fortunately there is a very long warranty for electrical faults. With my previous iPace, I had a similar problem.

Update: I received the new cable and guess what? 7kw charging still stops and starts erratically. Back to the garage for another investigation. I understand that there is warranty for the electrics but honestly I never had so much trouble with a car and for this price range I really don't know what to say. Its not because its electric. My Nissan Leaf still goes strong (six years) without a single fault and still has the same range.

I have similar issues as #3 PP1984. Got my EQS450+ in dec 21. Home charging with Nexxtender - Powerdale HOME | Nexxtender solution | Powerdale .
Since beginning impossible to charge 3F+N at 11Kw at home. When we changed to 1F+N 230V at 3Kw it charges without any problem.
2 weeks ago Powerdale finally changed the home charging device. No result same issue! At 3F+N 11Kw the charger goes on-off until the car gets error.
So no cabling issues or whatever.
It looks like there is an issue with communication between car and charger.
MB dealer has chacked the errors in the car and this was an error on phase 1 when charging in 3F+N.
Also checked the order of the phases (for those that understand electricity rotation order) Also this is correct.
When I use Ionity fast charging in Europe works fine. DC never had issues. AC however some charging points also have issues.
Campatibility in AC charging is a main issue here.
Pitty it takes long to get to the right engineers at MB ...
As I own an electrical installation company, I feel that i have more knowledge on electricity then the dealership....

Apparently it was a temperature sensor on the charging unit (faulty sensor thought the car was overheating) that was causing the problem (that’s what I was told anyway). It was replaced and car charges no problem now.

WOW! glad it finally was solved. The sensor being the issue makes a lot of sense. Sounds to me like the diagnostic tools in the shop, and the knowledge of the technicians could be enhanced and improved.

Can you clarify whether the sensor was in the car or the EVSE?

Apologies about the late reply (did not receive any notifications for months). It was a car sensor. Since then no problems at all.
