HV battery shutoff when initiating rapid charge. Vehicle control system fault.

[kimoluki]

Hopefully the May 2022 software update will be applied and all will be ok. Had my LR Trophy updated last week, but still haven't used a rapid charger yet.

I'm not sure that the new update fixed the issue... My car has arrived in the UK in April but was collected from Nathaniel Cars on the 30th of May. I was informed that the software was updated for me.
Lets wait and see what Leeds dealership has to say.
It looks like that on the way the 12v battery went flat (hope it's not a begining of 12v battery issues).
According to the AA guy 7 out of 10 cars with this problem are MG cars 2 out of 7 can be fixed by disconnecting the battery.

As was mine M5 northbound Welcome Break Sedgemoor Services.

AA arrived and sorted it out by plugging in a laptop and 'resetting' something.

You can buy terabyte sized usb sticks now!

I think these things are more related to variant coding and so on.

The system needs to be online for the proces to end properly.

Have seen this before, where the computer does a module wipe, then they load up the new firmware and then, based on VIN, the computer will variant code the car, and verify the update went well.

Variant code = Enable functions in the car, while NOT enabling functions not in the car (For example, a car with no reverse radars, should not try to use those, and a SR car should be set up for SR batteries, range etc)

Less than two weeks into ownership and I’ve had the VCS fault whilst attempting a rapid charge via a GeniePoint. Disconnecting the 12v hasn’t worked and it’s being recovered

This issue is getting serious!

@woz Don't supposed you tried to hold down the start button someone said 15 sec and it reboots

 

[N2STY]

It's OK mg said the zs is not compatible with rapid charges ie over 22kw

I was going to ask the same question. Was this tried?

If this WAS to work successfully, then it could be almost a life changer for Gen2 drivers !.

I am hoping @woz could try this before dealer gets there hands on it

The AA guy did. Didn’t work unfortunately

I'd like to know which of the many rapid chargers are OK! Either way it's the usual abdicating responsibility you get from some customer service people.

Course there may be other things the originator of this trick did before the long press?

Like clear codes (visible or otherwise) ?

Got to be worth an ask of the original poster of the long press trick?

Just an FYI guys, I had an issue charging at a 50kwh PodPoint rapid charger last week and this is the alarming response that I got back from MG “Customer Service”!

Wow, I wish the dealership had told me that! I had successfully used the same GeniePoint last week. Car is now with the dealership, I hope they can sort it quickly.

Same problem with my 2nd gen MG zs ev SR Trophy. Apparently it was updated before sale.
Brand new car arrived in the UK at the end of April .
Sold by Nathaniel cars in May.
AA guy have tried all tricks from the forum and now it is on the way to Luscombe MG Leeds...
I will report back how they handle the situation.
On the positive side AA told us 3h wait but the recovery van arrived within 30m

How long did it take to sort the issue Kimoluki?

The car is still at the dealership and I'm still waiting for the courtesy car. They have an agreement with "Enterprise " unfortunately no cars available in my area
so now we are down to courtesy taxi... option which is rather disappointing.

Someone needs a kick up the backside for that one. What do they think the CCS port is for?

 

[Lovemyev]

Someone needs a kick up the backside for that one.

Yeah accompanied by their P45 !.

Are we noticing a pattern emerge on what chargers are trending to cause this issue? I've only charged once on a rapid, an Instavolt with no issues but I've heard of issues with Gridserve and Geniepoint but has it occurred with any others?
