I'm on R42 on both my Excite 51's, but I installed it myself from a USB stick.

looks like R45 is out now too, that was quick ...

Hi guys…

New version for SE pre 2024 models. It’s available on my onedrive

It’s SWI69-29958-1100R45 and it comes with MCU 69.5.1.0

That's exactly what I have now, not updated since Feb 23.
Mine is going in for a service later this month, and they say they'll update the LKA thing, I'll know more after that.

Mine goes in on the 10th of March.

The "detailed" service description says they'll check for software updates and apply them if existent.

I doubt it very much but will see what they actually do.

There's nothing really "wrong " that i'd pay for, but smoother ELK/LKA would be appreciated I guess.

Nowadays I often can't be bothered turning it off on a long trip..but sometimes I still do.

Really with the negative 125 MCU version?
I have a feeling when the car was originally delivered I have a feeling i was on a version 60 something originally

The politics in MG AU now seem that you need to raise a fault issue with software in order for any update to be applied. Do not rely on them saying all updates will be applied. My local dealer actually lied to me gave alternate facts ( A Trumpian phrase) and said the ACC deceleration was a "design feature" to allow the car to achieve it's ANSCAP Rating. I guess my car now fails the safety rating.

No Fault reported = All is OK

The car is much more pleasant to drive since the updates.

I had the older AEB which you could not save the setting to LOW.
If I forgot on Medium it slam the brakes on, even on Low it did it a few times.

This was the reason they said they would do software updates.
Said they do AEB only although I know they did the cruise control as well, as it is now stepped by 1km.
No idea if anything else was done; was hoping the HVAC so 24°C is not 20°C, although summer has come and I have to set it to 24°C.

They must have completed all the up dates before we took delivery, coming up to 12 mths ago now, the temp seems fairly close to what is selected ....... the cruise control does 1km or 5 km increments, the LKA is just annoying, it doesn't take control as such, but it will move left every so often and then beep at me .... but I think that's just testing if I'm paying attention or letting me know I haven't turned it off yet
I love it when it beeps at the wife when she's driving .... when I ask why it's ok for the car to comment about only being in your lane when you are crossing it, but I get an earful if I say anything .... to which I get an earful anyway Me tapping the dash and telling the MG that it's ok, it's not your fault she can't drive between the lines .... doesn't seem to help matters either
