Power limited

[Bruce H]

My MG4 sr has developed a fault , if the battery level drops below 50 percent the car goes into power limited-limiting speed mode and small tortoise symbol appears. I am then unable to use more than 1/4 acceleration and drive over 50mph . Has anyone else suffered this fault ? , I am waiting for a return call from the service department at my local MG dealer to try and rectify this .

There is a couple of threads on this mate, to the point some cars have had motors replace and it didn't work, this has resulted in cars being rejected as the fault hasn't been fully figured out.
Yours may or may not be related to that

I think this is the first time though that anyone has mentioned the Tortoise symbol.

Yeah, that's why I said may or may not be related, I hadn't heard it mentioned either.

Well finally sorted , turned out to be a software issue with the battery management system. Car now seems to have improved acceleration which is a bonus as seemed a little sluggish before compared to the demo car I had driven before . ?

Fantastic, hope for us all ?? Is there any way you could post more detail? I'll speak with Perry's Aylesbury on Monday, be good to fill them in if they're not aware. Was it a BMS update?
