MB came back and said that one of the pins in the charging port wasn’t carrying any voltage. I guess that’s why only the DC charging worked.

The service writer said they had to reach out to the engineering department in Germany for permission to replace the entire charging port. No idea as to when they can get that part in. I should know more tomorrow.

I took my car back home yesterday. They’re shipping in a new charging port and I can continue to DC charge in the meantime. Should be about two weeks for the parts to arrive.
Glad I have those two years of free charging and lots of chargers nearby.

Hi, i have EQB and i have the same problem it started yesterday, i think it is something to do with the software, i will call MB today.
thanks

In my case it was diagnosed as a hardware failure with one of the pins in the charging port not carrying any voltage. Mercedes is replacing the charging port tomorrow and I should have the car back the same day they said.

I’ve been using DC Fast chargers in the meantime and haven’t had any issues.

I got my EQB back yesterday. We’re able to use level 1 and 2 chargers again. Fault codes detected were P0EF7FA and P0EF8FA.
AC phase 2 had 0V when tested while 1 and 3 had 210V.
It was a same-day repair. Took a while for the part to get in and to find a tech who could perform the work.

I had a neighbor who experienced something similar with a different EV and same ChargePoint device. Pretty sure it was something to do with his EVSE not providing enough juice and it would trip out. Easy way to diagnose would be to borrow somebody’s level 1 charger and see if that gives you any issues. That’s how we diagnosed the issue with our EQB
