EU MG4 (all variants) - Service campaign SC077 is out, improving lane assist performance

[Archev]

as

Our contract expires June 2026. While I'm not wishing the time away and still enjoy the car, I will be looking out for OTA updates in the next one.

ive now set off to drive the Berlingo threee times and had a message on the welcome screen telling me an update has taken place.
It’s not long since iPhone did an update in a similar manner.
I check the mirror every morning - but nah

I had SC077 applied at the second service and was told that the job time allowed to install it was 0.4 hours, as I intended to wait for the car it gave me around 2.5 hours to kill while they checked levels, replaced the pollen filter and key fob battery.

An observation re. TJA and LKA after SC077 ... TJA is much improved such that I now actually use it. However it still has the odd foible ... in that TJA will be assisting with steering the car, but will sometimes try to hug the inside lane line (e.g. when in lane 1 on a motorway), and by doing so LKA will go mental beeping that you're too close to the lane line!

Another observation following the last updates my car got ... the speed limit recognition system now ignores the National Speed Limit sign and shows --- rather than assuming a 60 mph limit.

Car's in tomorrow for the recall. Will be hard to compare as I turn lane assistant off anyway!

I got the LKA update during my service last week, (and also the latest infotainment update R63 for Trophy)

Its made a big difference to both LKA and TJA.

I drove around a lot of winding country roads on Friday to test if it had improved and it only beeped once without any steering movement. On main roads (when there was no other traffic around) I let the car move over slowly to the middle white line and it beeped and moved the wheel much more gently to the left, no lurching.

TJA worked for a 26 mile motorway drive the whole way there and back, it seems to have more gentle steering wheel movements and allows you to "override" more easily without having the "unstick the magnet" feel of older versions. The previous update last year had made TJA unusable as it kept veering off to the left and disengaging when it reached the white line, glad its been fixed.

On the infotainment side, android auto seems to work without any issue. Bluetooth however has asked me to re-pair my phone twice now, I never had that before. Maybe I need to completely delete the pairing a re-pair fresh.

2 years in and I still love the car

My turn today - bit confused when I handed it in because I couldn't find a service book or locking wheel nut where I usually keep them - are they not a thing on this car?

I hadn't noticed that. So I checked mine this morning and it did just what you say when I came out of a 30 mph limit onto a dual carriageway but then, when I came off a motorway where it had been showing 70 and went onto a dual carriageway it went back to flashing the derestriction sign at anything over 60, which is a pain.
When playing with the satnav settings (Trophy here), I found it had an option to show the speed limit, which I'm not sure used to be there (I could have missed it!). That one does show 70 for non-motorway dual carriageways.

The manual is a tiny booklet but it appears not everybody gets them. There are no lock nuts as standard on the MG4 as far as I know.

It looks like the satnav is using it's database to tell the difference between a single carriageway and dual carriageway. Presumably the drivers display software doesn't have access to that information, and so is no better than the SE models.

With a camera only, if you're on an empty dual carriageway and can't see the other carriageway, it often looks very similar to an empty single carriageway. You often see large arrows in the oncoming lane where a single carriageway road runs parallel to a dual carriageway for this reason.

With an SE it's a fair solution, but the Trophy could be improved.
