MG5 Charging issues with Ohme

I have the MG5 Excite SR and have been happily charging with and Ohme for nearly 2 years.

In the last week I have had issues when trying to charge overnight. I plug in the charger as usual and the car starts charging at 12.30am as expected but will then stop charging for no apparent reason.

Tuesday night it charged for 12 minutes and then stopped after only giving 1.3kwh. I restarted the charge and it lasted 42 minutes and 4.4kwh before stopping.

Last night I monitored the charge and had the following:-

21 minutes and 2.2 kwh before stopping.

Restarted charge and lasted 26 minutes and 2.7kwh before stopping.

Have switched off at breaker to cycle the charger but makes no difference.

Have spoken to Ohme who have advised that they have checked the OCPP statuses and the car appears to be going into a faulted state called SuspendedEV. This means the car was refusing to accept a charge which they usually see happen when the battery is nearly full, or there are settings in the vehicle or a third party app restricting the charge.

The only other thing of note over the last couple of nights is that it has been sub zero over night.

I'm going to try the granny charger tonight to see if the car charges as expected. If it does then it suggests the Ohme is at fault. If it doesn't it'll be a trip to MG to see if there is a fault with the cars AC charging system. Will be a bit disappointed if a car that has been problem free for 2 years suddenly has an issue with the charging system.

Anyone have any thoughts before I pursue MG?

Have you checked the state of the Control Pilot pins in the Ohme plug and the MG's socket? A clean with contact cleaner could help as would checking for debris.

Which Ohme do you have?
Have you tried turning the Ohme off at the CU?

OHME Pro, tried rebooting, from app, on unit and switching of at mains.

Try contacting Ohme via Facebook as they are pretty quick to reply or phone them.

I have tried they say fault is suspended ev so its the car not the charger, bmw been out for 4 hours and cant fault the car and will charge on both AC and DC chargers that arent OHME. Thanks for your help though

You havent installed a powerline adaptor for wi-fi? that can cause problems

No, nothings changed thats the strange thing, had car for 6 months, went on holiday for a week and didnt use car or charger and then the issues started.

Try disconecting the negative battery terminal (trusty old 10mm spanner) for 10 mins which will re-set car?

Solution found on another forum - delete car from OHME app, delete ohme app, reinstall app and link car again.

Has anyone else tried this and had it work?

Last night my MG4 didn't fully charge on an Ohme charger and Intelligent Octopus. When I plugged in, the Ohme app notified me there would be two scheduled blocks - one in the evening, and one for the core 23:30 - 05:30 hours. The first block charged, the second block didn't. Ohme tells me they got 'SuspendedEV' from the car.

I'm reluctant to reinstall the Ohme app, because I can't see any mechanism where the phone app would be the problem. Once the schedule is set, it's 100% between the charger and the car.
