Mg4 software versions

LKA when updated should now give 5mph increase when pressing the up button on the ACC (cruise control ) when it was 1mph increase previously. The R version has no bearing on LKA version.

If you want to update the infotainment you can do it yourself - instructions and files are available on another post in this forum.

If you still have disconnection problems after the updates carried out it may be a TBox issue but I would see how it goes.

Before this appointment the ACC increments were 5mph but now they’re 1mph. Is there anything else that can help pinpoint the LKA version I’m now on?

Thanks for the infotainment tip! I’ll look into that

Other way round, bud. Old method was 5 for single tap, 1 for tap-and-hold. Update changed that to 1 for single tap and 5 for tap-and-hold. The update also removed the aggressive slow-down when taking gentle bends with ACC active.

@noahb22 You'll know if the LKA update has been done, as the car won't try to yank the wheel out of your hands - it's more of a gentle nudge now.

1100R13 was what my car came with in November 2022. At first service this was updated to 1100R33, and at second service it was updated to 1100R38. No update at third service, but I did an update myself last week to 1100R45. (MCU versions were updated each time the MPU was updated).

Thanks @siteguru that’s very reassuring to hear!
