MG4 Software Update Thread

[mg4mc]

Software companies learned long ago that you want all your users on the latest (or near latest) versions**, it makes support so much easier, and behaviour consistent. As a car nowadays is just a computer on wheels, I do not understand why MG do not take this onboard.

** Standard support question #1 - What version are you running?
Standard follow-up - Upgrade to the latest version and if you still have the problem get back to us.

Just had the year 1 service and the following updates RC008 , SC47, SCUK001. No R46 unfortunately but have raised this with the dealer, evidently it's not a 'campaign' update so therefore they don't automatically do it. I have requested it specifically so I'll see what their response is. Any ideas what the other 3 are though? Here's my current system configs..

RC008 was the locking in recall ... mine was done almost 12 months ago (January 2023)! The other items can be seen in this post:

The MG4 SE 1100R33 Infotainment Thread

I'm finding it to be fine ... it's fixed a few things that previously didn't work (already mentioned), and I find the touch interface to be "snappier". AA also seems to start quicker.

What is EVCC and FDR for? I know I got the BCM last time, no mentioning EVCC or FDR.

As I replied to you the last time you asked I. DON'T. KNOW. The service garage deemed they were necessary per MG's service campaign.

EVCC = Electric Vehicle Communication Controller
FDR = Front Detection Radar

New amazing feature of R46!

When I am doing scheduled charging, the charging screen in the car now shows the correct time when charging will start. It always used to say start time 00.00 regardless.

Does the recent updates fix bluetooth connectivity issues? My Phone is hit or miss whether it's remembered or not and I have just given up as I had reconnected it over 10 times.

On my R46 infotainment I usually lose BT connection after 1-2 weeks and I have to do everything over again

 

[siteguru]

As this is a thread about the MG4, in the MG4 board, I feel owners of other models need to be clear if they also own an MG4 and are talking about that. Taken in isolation, @Able25's post doesn't make sense as their profile shows a ZS EV.

Have had my MG4 SE LR for 9 months with no dealer contact regarding software, so I'm on the initial versions (see attached).

Am I missing any significant improvements or fixes?

Thanks.

 

[Rolfe]

You probably want to upgrade R13 to R33. However, don't let them give you any intermediate update number.

You are missing some improvements and fixes - but they are only really significant if anything is buggy or broken that you currently use, so you will have to be the judge of the significance.

Certainly there are no major upgrades or new features, MG appear to focus almost all their attention on bug fixes.

They don't publish any information - we have to figure out here what has changed with each release.

If there's nothing wrong with your car, I wouldn't touch it as upgrades can always introduce new bugs.

 

[Rolfe]

There are definitely things wrong that R33 fixes, but they may not be things that Logan has noticed or is worried about.

Happy new year to all.

Now my question.

I took delivery of my Trophy lr just before Xmas, and have been getting to know it ever since. The infotainment system has been delivered with R40. Does anyone know where this release comes from and should I go back to the dealer and ask for the update to R46?
Also is there any where that gives a definitive list of the latest versions of the other software modules mpu, mcu etc.

Thanks

 

[NLMGSAN]

Should definitely have had r46. But that's only infotainment...

Yes, that is normal.

It comes from MG. For some reason they are only letting dealers install R46 when the customer has a warranty issue with an earlier release (eg bluetooth trouble).

Updates are not free, have to be applied by the dealer and are supposedly included in the annual service but in practice because they are time-consuming (manual process) to apply, some dealers skip them or install the minimum set only.

Also is there any where that gives a definitive list of the latest versions of the other software modules mpu, mcu etc.

Unfortunately nobody has this information including the dealers. MG keep it very secret.

Thanks to you and tsedge for your replies.

The main problems I see relate to the infamous lka, and also intermittent failure of auto hold, also the resetting of configuration each power cycle is a pain.

Other than that, nothing that's a significant problem for me.

Ps I've also had one erroneous slamming on of the brakes due to the front collision system, which was not well received!

Systems like LKA and Autohold are not part of the infotainment updates - there are separate car module updates for those (and many other systems).

The infotainment version number is just for the centre screen functions like Car Play / AA, sat nav (has separate map updates), radio, AC controls, settings etc...

There have definitely been many updates to a variety of car modules since launch and definitely some that affect LKA, not sure about autohold.

It is generally not possible to see what car module versions you have (with a few exceptions on the engineering menus) and we don't know most of the updates - some forum members have received info on specific upgrades their dealers did but there's no way to know if you already have them.

The best way to get car module updates is to report problems to your dealer and ask them to be investigated and fixed under warranty.

I've just been in to my local dealer (Lincoln, UK) to see if there's an update yet for the LKA twitch. They checked and said there are no campaigns at the moment. Owners won't automatically be told, we have to keep contacting them periodically to ask. They are reluctant to run any kind of update unless they really have to as it can brick the car and the head unit would then have to be sent away to MG to be reset.

(2023 MG4 SE LR, MPU Ver SWI69-29958-1100R16, MCU Ver 69.3.5.0).

Just out of interest, what am I missing out on if I'm still on R16?
