Having problems getting more than 3 kw when charging mg4 on our wall charger

I have a brand new mg4 (April 2023) to begin with we managed to get 6kw plus on charging at home.
Today I plugged it in as it’s desperate for a charge and I can only get 3kw. I have changed nothing and I don’t understand why.
Any ideas?
Oh our Nissan leaf still charges at its regular speed off the wall charger with the same cable.
Mg assistance were no use and the garage I got it from are busy until June. At present it’s taking me 12 hours to go from 25% to 80%
All and any comments gratefully received

Try it on a public charger and see if it goes over 3kw. If it doesnt it kinda confirms a problem with the car

Not sure if this helps but if you switch the charger off, check the plug resis1.5ktance between the PP Pin and Earth, if it has a higher resistance (1.5 k Ohms) then that will restrict the charge speed to 3kw. Open cct will stop the charger but there may be a higher resistance there. Make sure the wall charger has been isolated though. Like above isolate the car/ cable first, it may be the car!!

Thanks- yes that was on my list to do just trying to find a working charging point near us and I will have a go tomorrow.

Have you reduced the amps that the car charges at? Have a look at this video from Burt Solomons.

Have a look on Zap-map you may find a free one.
How is it on a rapid charger?
What network app do you have?
Watch out using PodPoint at Tesco's as they can reduce the charge rate to 3kW.

I had a similar experience. I was only getting charge rate of 3kW but was using the cable I had with my Audi A3 Hybrid. Swapping to the supplied MG4 cable and charging went to 7kW.
