Car ignoring 80% charge limit

It is probably a software update question. and I need to convince the dealer to do it.
Apparently, they are not paid by MG when they do software updates, so they are not very willing to do them

Partly true. They are paid if the update is for fixing a fault but not if the customer just asks for a software update.

I had a similar problem after a previous update. I complained to my dealer suggesting they had installed the software for the SR. They reinstalled the updates and the problem was fixed.
