MG4 Software Update Thread

[NLMGSAN]

Interesting. Across the pond they don't seem to have any knowledge of it.

 

[dutchymg]

Hopefully it releases in the next 2 weeks hahaha

Just back from my local dealer following some issues with all the safety features (forward collision, lane keep. AEB,speed limit recognition and ACC all unavailable….) and they said they got a message from MG yesterday in relation to the Which article. They are in the process of finalising an update to the software and when ready all the dealers will be asked to contact all MG4 owners to schedule in the update.

Let’s see if it happens that way!

Just curious - which dealership was that?

So got my 24 plate SE SR updated at the dealer. Logged with fault around regen resetting to level 3 as that's the only way they would look at it.

Updated from

MPU: SWI69-29958-1100R21
MCU: 69.3.5.0

To:

MPU: SWI69-29958-1100R33
MCU: 69.3.8.0

After pickup my car was faulting on all safety features so had to quickly turn around and take it back. They had to perform the update again as apparently one failed to take and the car rejected it.....

However, the regen still resets to 3. Apparently it's by design and can't be fixed.

Let's see if the other niggles return like the shortcut buttons forgetting what has been set etc...

At least I can now swipe down to switch off LKA.

CarPlay still is laggy imo.

Also frustrating that the rear window lock doesn't remember its setting. Allowing my kids to open windows if we forget to disable each time we get in the car.

It's like Dory!

Regen always defaults to 3. Same as drive mode always defaults to Normal, and LKA and other assist systems default to On. The MG4 doesn't support driver profiles, so the defaults are deliberate because the next driver may not be the same as the previous driver.

Stupid it sets it to the most aggressive mode though. 1 I could understand but 3... just don't get why.

I wouldn't want to use anything other than 3 unless I was going on the motorway, why would you not want to get as much charge back as possible?

Or even one pedal driving in the newer models

Or Adaptive. It is slightly milder than 3.
Btw, I have placed regen under the button. So changing it is no problem at all. I use that button regularly, switching between 3 in town if OPD is off, and adapative on the highway.
I like OPD very much. Very relaxed. But I must remind myself that at higher speeds you still need to use the brakes from time to time. I deactivate OPD if ACC is active. I could use a button for OPD though...

To me feels way more aggressive than standard engine breaking you get in a manual car and no doubt just personal preference. Coming from driving an Ioniq for 3 years which had pedals to adjust the regen I hardly ever ran in the highest.

Adaptive is what I normally switch. Just wish as the owner could stipulate this. That's all.

Yeah I tend to move from 3 to adapative via a shortcut button on the steering wheel. Occasionally I've seen this shortcut button forget it had anything set. Will have to see if that happens after my update.

I only tried ODP once in this car and wasn't a fan. Need to give it another go really.

Then you need an update. There is a fix for this.

Almost 2 years in with the same car, I find regen 3 perfectly fine.

 

[Ian Key]

I use regen 3 all the time too and by feathering the accelerator pedal I can control the amount of braking it applies.

The most efficient regen is none at all, as regen is not 100% effective ie it loses some energy with friction, heat etc. hence I use the mildest setting for maximum efficiency. ie youre getting 70% back but having to put in 100% to get going again, thus losing 30%.
Think about it, youre slowing down more so have to accelerate more, unless youre coming to a full stop.
I always remember when Diesel Car did the record economical driving run to see how far they could get on a tankful, the most economical use was not braking at all! Anticipation rules..

You only slow down to the necessary speed for the conditions/event. Makes no difference, the end speed will be the same, regen or no regen except using regen will generate a pay back in energy terms, without regen it won't. Just because you use regen, it doesn't mean you slowing down to a lower speed than without as that's just bad driving and not adapting your driving to accomodate regen.

 

[mikgle]

As I say, because regen is not 100% efficient ie you dont get back all of what youve put in, the more agressive the regen the more inefficient it is (in terms of saving power). I suppose what I'm saying is, if you slow down TOO MUCH or TOO early, youve wasted power and this is much more likely the harsher the regen.. anticipation saves you having to slam the brakes on, or in this case, regen.

 

[siteguru]

Feathering the throttle controls the regen .. just saying .....

A good example is when on adaptive cruise control.. my mg4 tends to rush up to the car in front then slams quite harsh regen on, even with different closeness settings.. much better to knock the speed back a little and be gentle about it. Smooth driving better than stop/ start..

True. It is far from 'efficiently adaptive'. But that's not because of regen. It also happens if regen is low. It is an error of the ACC, not of regen.
