SC098 service campaign - full software update

[unleashed]

Given that your profile says HS PHEV .. do you also have an MG4 Urban?

(Apologies if this has been confirmed elsewhere).

I have access to all carlines from MG

No, the picture I sent is from a Comfort 43 kWh (latest version 8.1.1), for the Premium the latest version is R29.

In Germany they call this the active trim

Local market options, in Iberia all Comfort builds come with Heated Front Seats + Heated and Leather wrapped Steering Wheel

then i'm confused as to whether there indeed is only one software version or multiple versions.
and whether the version numbers are specific to the particular market: comfort in uk does not have live services either, so the interface is a bit different. and we saw that with the original MG4 in SE trim vs Premium

Those specific options mean nothing regarding software, as per usual with more recent MGs there are 2 different softwares: LOW and HIGH (regardless of what each market calls the trim levels or included add-ons/optionals). LOW can usually be updated by the dealer through USB with some additional validation steps, while HIGH can only be updated through the diag system connected directly to the car (surely due to additional services validations/activations).

are there any release notes about the latest update for the LOW spec? Any Service Campaigns you are aware of? any difference you noticed since upgrading?

Release notes usually only state "Bug fixes", I couldn't have noticed the difference as our cars were already handed to us with the latest software from PDI last week.

Little strange software updates aren't done at home. So do the MG dealers just update when taken in for the service every year, of do they ask customers to come in and update?

Unless you don't complain it's very likely you won't get any updates at all. Most dealers only do them of you complain about a certain thing not working or not working as expected. MG and software updates are a little strange..

Oh right, okay, I'll make a point to ask for software updates when I get my yearly service then. Thanks. Yeah a little strange.

Even then most dealers refuse to provide you with an update. You really have to specify some kind of problem so that they have a reason to update. There might be exceptions, but unless MG isn't having some kind of recall (like SC77 for the MG4 that fixed the LKA) I wish you good luck finding someone that keeps your car up to date with out charging for every single update. In case of the MG4 you can do most of the updates yourself but if you brick your car while doing so, it's very likely your problem as this is not the official way of doing it. The car however is very resistant and plenty people do it. Even when some thing went terribly wrong it was always fixable (as far as I know)

And some dealers also will just straight up lie to you, claiming that there is no update available

If it's a recall it's mandatory, if it's just a TSB based on customer complaint they still get a warranty based fee to perform it. If one lies and the other performs it just report the first one to the brands' customer care and they'll probably be getting a written formal warning.

MG doesn't care, at least in my experience- They will apologize and what not but nothing is going to changes unless you take matters in to your own hands. Again, there are dealers out there that will help you but the problem is MG themselves: E.G in Germany, dealers only get paid for providing you with an update for your ev if MG approves it. If they just do it (because they like you as a customer) they risk not getting paid for the work done. This is because of the "Agent Sales Model" that MG makes use of for their ev's here. Luckily, it will expire in Germany at the end of this year so then you can start blaming the dealers. No idea how this is in other countries but from I heard from UK owners - service seems to be the same (just got more dealers to choose from).

So right know, you need to give MG a reason to approve the dealers request for an update or just do it your self.

If it's a recall it's mandatory

If it's an official one yes but I think most of these were just internal ones (like the LKA of the MG4 or the issue with 3 Speed automatic transmissions where the car didn't shift properly). In Germany, I still know some people with 3 year old cars that have the LKA issue with the MG4 and just gave up on trying to get it fixed. They just wait for their lease to expire..

But this is not an MG exclusive problem: Litterally anyone that I know that drives a newer VAG vehicle (doesn't matter if ice, hybrid or ev) has issues and they can't even fix them because most of the shops only do one update at a time. A coworker of my father drives a Skoda Enyaq and was in for a software update 7x until it was fixed because for the first 6x they only did one update at once and only after escalating they took the car in for 2 days and then finally did all updates (which fixed the issue).

Don't even get me started on the issue where all assistant systems will fail at once in you vag and the only way to fix it is to stop and lock the car. I know like 10 different people with different brands (Audi, VW, Skoda..) that experience that multiple times a week and the shops can't fix it..

So the MG strategy seems to be "never touch a running system"

wow ok. Well hopefully the dealers are a bit better here in Australia. Thanks for the info guys. I'll let you know how I go.

Just had my MG4 Urban into the dealer for the 1000km/3month check. They completed the "recall:" software upgrade SV098-AH4EM ay Ferntree Gully Vic Australia.

SV098 is a major internal manufacturer service campaign/software update for MG electric vehicles. "AH4EM" is the specific module or software version designation associated with these updates. What the Update Addresses Infotainment & Connectivity: Fixes system lag, connectivity bugs, and screen freezing issues (like Apple CarPlay/Android Auto dropouts).Safety ADAS Calibration: Improves driver assistance features such as Lane Keep Assist and the Emergency Braking systems. Battery Performance: Optimizes software logic regarding 12V battery maintenance and range/powertrain management.

please let us know if the update has introduced new bugs along side fixing the existing ones.

Hi all

Thought I'd share that I took my Urban in for an SC098 service campaign recall. today. Apparently it was to update ALL software. Unfortunately, at the end of the day they called to say they couldn't get the software to load and so have had to go to MG HQ for advice. Anyone had this recall yet and if so, were you more successful? Thanks for a great site too

did you get the update done?

 

[T08Y]

Just been back to dealer for second attempt at installing SC098 updates. They say they can now complete these via a wired connection as first time round, OTA didn't work for them. Hopefully will get car back tomorrow.

I can confirm what @ColinA says though that the module is AH4EM X1. The software that will be installed is as follows, i.e. pretty complete and includes application, calibration and configuration files:

BMS
Base Mode: 12113045
Application Software:12126158 or 12126149
Configuration File: 12139192

EPS
Base Mode:11739258
Application Software:12178359
Calibration File: 12075992
ECU Calibration File 02:11772009
Configuration File: 12121048

FICM
Base Mode: 12211255 or 11797879
Application Software:12139115 or 12174786
Secondary Application Software: 12139116
Configuration File: 12071241 or 12103365

VCU
Base Mode: 12386578
Application Software: 12179222
Calibration File:12179223
Configuration File: 12096718

@fnegroni I'll report back on what changes these have made and if ADAS is noticeably better as a result once I get the car back and have driven it for a while.

I think AH4EM X1 was the internal project name for the MG4 Urban when it was being developed in 2024.
