MG4 Software Update Thread

[NLMGSAN]

Just had R59 installed by the dealer and cruise control still goes in 5 mph jumps with a single press. I really hoped it would be changed to 1 mph like my old Suzuki Swift

Insane....

This comes with an ACC update, not with Infotainment. Complaining about poor ACC performance (hesitant, phantom braking, not working on corners) got me this update and now the system works brilliantly (as it should have done first time!).

What do you relate to 'hesitant'?

That is odd. Mine got the service campaign updates which MG automatically install but no infotainment update (still on R33 and happy with it) . But mine now has the 1mph increments so the campaign updates must include this so I am surprised you haven't got that.

Yep. Before the ACC update it slowed down like crazy in curves. After it is fine.

Despite not giving me the R33 I was literally screaming for, my dealer did at least manage to give me that one.

Interesting, I always just assumed that was how it worked!

In my car it's 5km jumps on each tap, but you can hold the knob for 1km increments.

The new updates reverse that and it's a lot more intuitive once you get used to it.

Slow to react when the gap to the car ahead increases, jerky sometimes.

All went away with the update. It isn't perfect now - occasionally there's something it doesn't like about a given road or circumstance - but it is 95% there and I use it a lot whereas I had to stop using it at all before.

Can someone try typing

#*#0112*#*

on the phone keypad.

We all know about 4479 from the manual, but this popped up in the code and i'm keen to see if it does anything

Well it says map engineering mode enabled, so I guess next stop is the navigation apk to see what it does

Interesting. I saw some strings that say it should turn off if the car starts moving, otherwise a restart should get rid of it.

Mine isn't slowing down on bends now, but it's still refusing to pass parked cars even though the gap is fine, unless it's following another car. Except, if there are cars parked on BOTH sides of the road, it often goes through. Weird.

The version I have still responds like hesitantly, but it happens in two occasions.
One is in slow traffic or traffic jams where the distance to the car in front has decreased to less than the distance set (smallest). It looks like it wants to create a gap.

The worst hone is the second, when it keeps reducing speed when overtaking a slower car (mostly trucks) at usual highway speeds, even when the indicator is on and I'm in the other lane already. It can drop from 100 all the way down to 89 kmh. Caused middle fingers of drivers behind me....
Here, a standard line between lanes on a highway is 3 mtrs long. Distance between them is 9 mtrs. Usually, I count four, occasionally 3 ahead of me before I put the indicator on. That makes at least 36 mtrs before I start the overtake!

Question is whether it is a lazy hesitant system, or a biased response to the right side of the car. Maybe it is both but the bias evidence is quite strong. There is another occasion where it happens: on a 80 kmh road with traffic lights. All traffic lights are on green, me approaching the junction with 80 kmh. Cars in the right lane going for the right turn are very slow. When I approach them from behind in the lane to the left of them (going straight ahead) the car starts to break as well. That has caused a very near collision with the car behind me because nobody expects this (all lights green effect).
Disabling ACC solves it. It happens irrespective Lane Assist or Front Collision Assist (whatever mode).

With refusing you mean it slams the brakes, or just drops in speed? Or does the car prevent you to cross the lane markers to overtake the parked car?

Finally after a year of back & forth to 3 different dealers three irritating problems fixed, garage said today that they updated 9 modules. Now scheduled charging , HVAC & a frozen driver display screen fixed .

What was wrong with your hvac? Was it the temperature issue where you had to add 5 degrees? If so I’ll go get mine done.

 

[Rolfe]

Nah, that's never been fixed.

 

[tsedge]

Nah, that's never been fixed.

I believe I read somewhere here that this is due to how Chinese cars measure temperature (inlet vs outlet) and as such it is characteristic of the car. But I can't find a reference to that, sorry.

 

[Rolfe]

Bjorn Nyland did a video about it. He showed that the temperature of the air coming out of the vents was the temperature shown on the screen. The net result seems to add up to a 5-degree discrepancy with the cabin ambient.

 

[tsedge]

Thank you, that enabled me to find it:

I recently had my infotainment updated and it fixed the iPhone Blutooth issue for me, finally. They said there’s a new update coming soon, but it hasn’t been finalised yet. I wonder what that will include.
