Yellow battery gauge

[ozzz]

My car has done the yellow thing a couple of times with no obvious reason I can tell you it is not cold related that’s for sure .
Also I charge my car to 100% most of the time as recommended by MG for the 51kwh battery in the MG4.

The yellow battery means that your 12v battery is low & is in the process of being charged by the high voltage battery. After finishing your journey or plugging it in it should go back to green.

As long as it doesn't turn this shade of yellow, it's fine.

Given that it's the HV battery SoC indicator that goes amber ... sorry, but I don't believe you.

That isn't what the yellow SoC bar on the infotainment screen means, which is what we're talking about.

Does anyone know the reason for this?

It supposed to change colour according to the state of charge I believe. But it appears that most cars stay green all the time and some randomly change to orange. It will probably go green again when you turn off and back on again.

This is one of those mysteries of the universe no one has a definitive answer for. It does not cause problems apart from messing with your head, then disappears back to green. You will find yourself going 5mph slower whilst pondering the problem, maybe that's the function?

I just merged this in with the ongoing thread about the issue. Have a read, @fatih.

I think it is maybe trying to show you the state of the driver.

Yellow = queasy from spirited driving.
Brown = an XPower movement.
