MG4 Software Update Thread

[Cabansail]

They got back to me and asked if I can bring the car in again next week. They will evaluate it. Hopefully this will allow the Software Update.

Hi all down under, in the UK I had the issue of the car slowing down in corners, after an update this annoying issue stopped, you do have to be a little bit more aware though as if you are in ACC and it is set at say 60 mph and the corner should be taken at 30 mph then you have to do stuff! The LKA here has been updated a few times, each time it got a little better, but even now I get annoyed with it and disable it every time I drive. I saying this after having the car from new in 2023, and there were issues with the charging at the beginning but now all is good.

I'm not sure ACC is suitable for use on such roads. Here it would mainly be our longer highways and city motorways. When you get this sort of sign...

As I mentioned MG changed its instruction to dealers between the time I booked in for the 40k service & the time it actually went in for the service so NO software updates were done. I complained that based on the agreement when I booked it in it should have been done & they eventually relented. It goes back for the software updates Wednesday next week 6 weeks after it should have been done.

I have prepared a list of things to be resolved. See below
List of Issues

1. Infotainment System
   HVAC Temperature control wrong (5-6 degrees too low)
   ELK button on quick pulldown menu
   Bluetooth connection not remaining in memory
   Satnav update for route planning​
2. MG PILOT Issues
   Sudden unexplained braking (AEB) while driving with ACC. Update (AS-TEC-0722024-01)
   Car slowing down on motorway curves when in ACC
   Complete loss of all safety options incuding ACC, Front Collision, LKA, ELK & AEB systems when cruising with ACC on. Last occurred on 15/11/25 on Pacific Highway on 80 km section near Maclean ODO approx 31350km.
   Aggressive and dangerous LKA steering wheel control sometimes pulling towards oncoming traffic. Update SC077, UK.​

Also not done from last service when requested. High beam way to high. It is aimed up in to the trees. Good for road signs a long way down a straight road but there is a dark unlit gap between low & high beam.

There may be a few other things I have forgotten about or am not too concerned about. Overall though I love my car & its driveability. I love getting on a winding country road & going for it. It feels so planted on the road & that instant EV torque with RWD out of a corner is exhilarating.

I also asked for the High beam to be adjusted down as it is up in the trees at night with a dark gap between low and high beam. It seems that this has been a common issue from the factory. This wasn't done so I will ask for it again.

I have a darker spot between beam pattern, didn't realise it was an issue, but would be nice to correct.

Do they adjust the full beam down, as if they increase the low beam up then prepare for a lot of angry motorists as they seem to sit quite high as default .

I don't have any such beam issues in mine. Maybe it's because the Trophy/Luxury/Whatever it's called in Aus uses different headlamps vs the SE/base spec model?

PS - the numbered roller control certainly works on the dipped beams on my car. 0 is the highest beam and lights up to just below the hatchback lip/just above the rear numberplate on the car in front (e.g. MG4 type car, when it is 2 seconds ahead). The higher numbers drop the beam progressively.

Oh, I'm just popping over to Darwin, see you in about a month !!

 

[Corindikev]

The low beam adjustment works fine. The high beam is just way too high.

The SE has fixed units in that the low and high adjust as single entity. The Trophy lamps are individually adjustable low & high. The factory high beam adjustment seems to be way off on many cars.

I hate the headlights on my MG4. On our roads, if going around a right curve the road ahead is dark. And the never ending flipping on and off of the auto high beam.

Exacerbated by the stupidly bright display screens, even when on their lowest brightness setting.

I really dislike driving the car at night.

And the never ending flipping on and off of the auto high beam.

Huh. I don't drive much at night where high beam is appropriate, but the few times I have, auto high beam has worked quite well.

Mine is a 2024 extended range (LR here). It may be a firmware thing; I found that most of the things people complain about with firmware are not a problem on mine.

Infotainment excepted; it has many niggles.

 

[Cabansail]

I have often gone back to Manual High Beam as it annoys me when I blind oncoming traffic. The on/off is also a bit annoying but does seem to be the way of many auto high beam systems. They seem to get reflections and lights confused.
I did actually work out a system which would fix these systems, but it would add cost. If they had a modulated IR LED's on with the High Beam, then the sensors could differentiate the return. The reflections would be modulated and the lights would not.

You can apt to turn the centre display screen off. This may help a bit.

I still want the information, just not to be blinded by it.

I live on a country road, forest. On our roads it constantly goes on and off on some sections. It makes seeing far more difficult than it need be. But the big dark spot it leaves is the worst.

I presume you've set the Infotainment to Dark mode? I find that this is OK for me - in fact I have to raise the brightness a little from minimum.

I also always put the map on at night time too (even when not needed), as it makes the screen dimmer than having the "bright" tiles on.

My headlights (Trophy) were adjusted by the dealer early on which got rid of most of the dark spot. They're still abysmal when going round corners or looking for a side turning on our rural roads as they just don't spread any light to the sides. I turned off auto high beam soon after getting the car.

Yes.

I've tried that, still too bright. Night time interior light pollution is pretty bad with this car.

I think an added light bar may be the go for the headlight issue.

Local auto electrician or DIY?

 

[Cabansail]

That was DIY. Fitted on the Number Plate Bracket. To keep it from blocking the front camera I got a thin bar. It was an order from Aliexpress.
The Relay supply is taken from the loom going to the actual high beam, that way it dips with the Auto function. I put the switch on the left side of the Wheel Binnacle, so it's close to the Light control switch.
It does not give light like driving lights, but instead a general fill of the light pattern.

Ive just Purchased a Sep 2025 pre Reg Xpower. What software version should this be on. Seems to be blowing out cold air at 22deg C. Also Sat Nav seems to be way out of date
