Yellow battery gauge

[mikgle]

Your car must be running an old software.
The bar was fixed long time ago now for the SE SR

Possibly fixed now as it hasn't gone orange since the service in January..

Mine went amber recently, but I think it was before I got R33, which was only last Friday.

Hi guys. Anyone any idea why on my infotainment screen on my MG4 SE, the normally green battery turns yellow even when the percentage is reading 85%? After several power-offs it goes back to green. Just curious if anyone knows?

 

[siteguru]

Just search this board ... it's just "one of those things".

Since I had my last updates nearly a year ago (including 1100R33) the only time I've seen a yellow/amber battery is when the SoC falls to 9% or less. (It goes red below 5%).

Merged with the existing thread on the issue.

This is an entertaining thread! Mine has been green for all of the 3 months I've had it, but this morning it randomly went amber with 96% charge. Seems a little overcautious...

.. as @siteguru noted.... its just one of those things! ... I've seen it once or twice, but not noticed anything notable!

Mine only did this when the charge drops below 6%

Mine did it at 100% once.

Mine did it at 100% once.

Ok, you win!

I think I even took a photo. It was the first time I'd seen it. The key is to look at the driver's screen. The bug only affects the infotainment screen and the driver's screen stays green. When it really means it (at about 12 miles range!) all the screens will turn amber.

Ah, here it is, from earlier in the thread.

If you do a balance charge at 100% does it go green again?

 

[AndyL61]

This is supposed to be a traffic light system with green down to 40% , amber down to 15% and then red. However this has never worked on the MG4 apart from these random amber occurrences. It's another example of the software being flaky.

Where are you getting those figures from? Or have you just made an educated assessment?

What I have experienced in my car is green down to 9%, amber down to 5%, and red below 5%.

It goes green again on its own pretty soon.

I think other MGs do that so it's a reasonable assumption the MG4 has faulty implementation. As far as I can see the amber colour comes on at 12 miles remaining regardless of % charge, and I have never seen it go red.

This is a ridiculously low point to set the colour change at. If you're not aware you're imminently in need of a charge before you're at 12 miles of range, the tiny remaining stripe of orange on the dashboard isn't going to do you a lot of good.

The figures came from a ZS owner. I thought it would be the same.

But the HV battery symbol on the driver display changes colour too, so the length of the battery bar is irrelevant.

 

[Rolfe]

It's still silly. The ZS has it right.

Hi there MG4 owners, I am Dave from Bristol and have owned a standard range MG4 for over 2 years with very little trouble, but the other day I got in the car and the battery power bar which is normally green lit up orange. is there a reason for this. many thanks Dave.

It's a software bug. Mine does it from time to time as well. It's happened this week for me, which is the first time in ages. Resetting the infotainment by holding down the home button resets it back to green.
