Hi Folks. We have an issue with our Mercedes B250e. This morning my wife unplugged the charge plug from the socket and got in the car to drive away. However, the car still thought the plug was still in the socket. Also, when looking in the socket, the small locking pin that keeps the plug in the socket when it's locked was popping in and out repeatedly.

She's tried plugging it in, locking the car, unlocking and unplugging, but it still says it's plugged in. Green Flag had no idea (can't say I'm surprised) and they called Mercedes and they had no idea either (again, not surprised, but is annoying). I've even called Tesla (as the EV system is from Tesla) and they refused to comment for Public Liability issues........

Green Flag have offered to recover the car to where-ever we want, but as the car's park brake is on it can't be towed, or even dragged onto a low-loader, so I guess the only way forward is to have it towed with the front axle off the ground. And as the car is parked in front of our garage that houses as weekend car, we can't even get to it so my wife can go to work.........

Has anyone else had the same socket problem, or have any advice? I would have thought that it wouldn't be a specific B250e issue as the socket should be a standard type-2 design. I'm also guessing it's a moisture issue as we had a significant storm yesterday.

As for where to get the car taken to, does anyone have any suggestions for EV specialists near Banbury - Bicester - Milton Keynes - Northampton? I'd rather the car go to somewhere that knows what they're doing rather than a Mercedes dealer who probably won't have a clue and would 'charge' the earth.....

Here's a short video of the issue.......

Cheers.

If it’s under warranty get Mercedes to come and get it!

sounds like the actuator has stuck, try squirting some wd40 on the lug and retry.

Unfortunately it's not under warranty anymore. I did wonder whether some WD-40 might help, but it doesn't seem to be stuck, it's just operating when it shouldn't. I'll plug in my fault code reader when I get home to see if anything shows up. That might point me towards something.......

It might be the feedback that's faulty - could be a microswitch that detects the pin. Or even a bad connection.

Maybe get some high pressure air in there, to see if that blows anything out?

When my car died they dragged it onto a flatbed with the handbrake on. Otherwise you'll need dollies, which is a faff.

Right then. Had the car recovered to Mercedes in Oxford. They say it needs a new locking pin solenoid. Yay I thought, not too expensive....

How wrong! Apparently the access to the solenoid is very difficult, so the bill, for the part plus labour is over £500!

Has anyone else managed to access the charge port on a B250e? I can't believe it's that difficult, surely it's just a case of removing various trim panels from the boot (trunk)....

But, then I realise that it doesn't matter how difficult (or easy) it is, as they have the car and it's undrivable, so I can't just buy the part, drive home and fit it myself (unless I turn up at the dealers, ask them to push the car out into their car park and I have a go at fitting it).

Oh well, Merc 1 : Me 0

If it has FSH with Mercedes I'd try and get some good will out of them. Costs nothing to ask. How far out of warranty is it?
