Trip to the midlands & back- tried an AC charger at the destination, didnt work- put it down to a random niggle.

Tried it on a CCS charger five minutes from home, same problem.

Have whipped out my trusty 10mm & disconnected the battery, anyone got any bright ideas?
 
Only all the usual checks which I presume you've already done (schedule, % charge, etc).
 
There is a thread on this relating to rapid charging.
There seems to be an error code relating to the car showing a high battery temperature . I'd be interested to see if disconnecting the 12v battery works
I've not been able to rapid charge for about three weeks . Seems to be following an update during a service in my case .
Unfortunately no MG dealer in my area ( I've tried Romford Basildon Southend and Westcliff) can see me until January !!
MG East london servers are down so they can't even get my car to talk to SAIC .

I'm starting to get a little frustrated

Yeah, checked that (twice, in case I’d had an outbreak of ineptitude).

48 miles range left so my choices were limited. MK MG said 14th December, Bedford 16th December, Aylesbury; February (!). No firm promise of a hire car via the dealer, trying the “WTF am I supposed to do” line fell on deaf ears.

Sidenote- MG’s customer support (dealers and centrally) is horrific. People very pleasant but the “main customer service” 0121 number got me through to someone in Newcastle who suggested I sent an email. Not their fault if thats all they have been told to do, but the management need slapping with a wet kipper.

AA man (via MG) came, unsurprisingly said its foobarred and nowt he could do.

Dropped it at MK MG, and service desk girl could not have been nicer. Took my details then said “we normally get a first look between 3-5 days, you did say the car wasn’t working to the booking people (re the 14th Dec first available appointment) didnt you?”

Through gritted teeth & clenched fists- “yes, yes I did”.

Hire car for four days via AA/MG. Fortunately on holiday Sunday so that solves part of the no-car issue.

Moby has done, to date, 32500 miles and been trouble free until now. He’s a) under warranty and b) leased with maintenance so any costs aren’t my problem but JFC they really need to work on their service processes.

So after three phone calls & two emails, no response from the Garage. No direct number so forced to go through Glyn Hopkin centrally & they can’t seem to get hold of the garage.

Moby could be fine, could be not- nobody seems to want to tell me!

[ETA]- Pretty sure the actual bod(s) I speak to on Monday morning when I go there will be lovely, its the getting-through-to-someone-with-a-brain bit that’s proving difficult

Further update to the saga-

Presented myself at MG MK this morning, Told by person on the front desk that servicing bloke “was busy, he’ll be with you shortly”.

30 minutes later I’m still sat there. Grumpy mode engaged.

Finally spoke to him- “sorry sir, I wasn’t told that you were waiting”- they’ve done several SW updates but that didn’t cure it (sigh, I’m 99% confident the charger is blown and just needs swopping out). MG central maintenance bods have asked them to deplete the battery and then see if that cures it.

In better news, they have chucked me keys to a Leaf and I plan on holding it hostage until Moby is out of intensive care.

Again, once you have got through to someone with decision making abilities and a functional brain cell, you’re fine; its just the acrobatics needed to get to that point that are a significant source of frustration.

He’s alive!

Checked via the app- he’s on charge at the dealership now, one assumes that the issue is fixed. Not been told by them yet (although I am on nights this week so not expecting a call).

In other news, the updates appear to have fixed scheduled battery heating & travel plans- neither of them have worked for me before.

I assumed mine was fixed until the dealership told me that they don't have a rapid charger!
I told them it charges ok on a granny or ac charger! grrrrr !

That’s unfortunate.

Had an email, picking him up tomorrow morning & will try a rapid charge to check that.
 
Please post back on what was the actual cause of the problem ?.
From what the servicing chap told me on pickup, there wasn’t an actual physical problem- the BMS had just got its knickers in a twist.

Fix was applying various software updates, discharging the HV battery, then full recharge.

Had the car received any updates to the BMS previous to this visit ?.
I ask because the ZS EV ( Gen1 ) was intended to have a BMS update applied, although we know that some cars never received the BMS update at normal service time.
Could your car be one of the cars that never received the BMS update ?.
Some dealers responded when affected customers were experiencing problems with either charging, or reduction in range and sometimes power out put as well.
A few forum members had this very issue.
Charging via a D/C rapid to regain range, just made the problem even worse !.
This problem came to light, when some cars had become infected with a software bug, this happened when the dealer carried out updates like the HV fuse update, or even the comfort 2 update.
Not all cars were affected, it was very date dependant when the updates were applied.
The fix from MG was to overwrite the affected cars, with a software update to the BMS.
It was first intended that all cars would receive the BMS update at annual service time.
But not all cars received the BMS update, we know this because there are plenty of Gen1 models running perfectly fine on the bug free original factory software.
When modern cars / mobile computers are presented with issues today, the first thing the manufacture will request, that the dealer should ensure that any available updates are applied.
This done on an individual basis by reading the VIN number of the affected car.
No request to replace any parts will be authorised by the manufacture, until this process has been completed and the problem still evident.
I am a little confused here, because a few days earlier the dealer had updated the software and it did not provide a satisfactory solution.
So, what brought the car back to life ?.

I'd not had any updates previously- for some reason Perrys Aylesbury didn’t want to do them at 1st & second service (n.b Moby is a gen 2).

So got mine back from the dealer on Monday .
Whole bunch of updates done including the infotainment one (R33)
Tested rapid charging at Tesla at Lakeside on the way to work on Tuesday morning and Hey Presto! it worked .
Feel much more at ease now. I don't do many long trips but the the thought of not being able to charge if I did have to do one was making me rather anxious .

MG4 model ??
 
It’s happened again. This time en route to North Yorkshire. At least I managed to get to MG Leeds and not stuck on the side of the road or at a service station.

Only thing I can think of that caused it was going for a 100% charge again.

@Sam Luscombe any chance of a loaner- I’m the tubby one chain smoking out front

After some more swearing, and a significant increase in blood pressure, Moby is hopefully on the mend.

MG MK have replaced part of the internal chargeport wiring and, subject to further tests, getting him back on Thursday.

So, he’s back in my greasy hands, no more “manual gearbox & manual handbrake, how quaint” when tooling around in the MG3 courtesy car & certainly won’t miss shelling out on petrol.

Interestingly the Battery Preheat option has just appeared in the app, wonder if there was a HW version v Software version issue.
