2025 HS PHEV Software Versions, Issues and Fixes

[aerofurb]

I thought a new thread just about software versions, successes and issues might be a useful place of reference.

My 2025 HS Trophy PHEV software level from new (October 2024) was at 'R46.

I presume some Over The Air update scuppered the road sign recognition and associated cruise control, a couple of months ago.

Up until then everything was fine apart from the first service appearing on the screen as being due at 6k miles.

Evan Halshaw in Banbury are now an MG dealer and have been brilliant. When I bought my HS, they were Citroen and I didn’t exactly gel with the after sales side of the supplying dealer. All the staff at Banbury MG are very friendly, informative and not at all patronising. Other dealers could take lessons from them on customer service!

My car went in for a software update yesterday – that ended up with the road sign recognition and cruise control working, but the ‘star keys’ stopped functioning. Banbury MG then contacted MG and got the next software version (as I understand it) and loaded that this afternoon. Now everything works and the 'next service due' is showing at the correct 15k miles.

Current software version is now 'R62

I now have a fully functioning HS again – happy days and thank you Banbury MG!

Mine had been at R46 since new and up until the fix this week.

When the star keys stopped working the SW version number didn’t change.

I’m guessing it was caused by an Over The Air update seeing as one day the speed limit recognition/cruise control worked and the next morning they didn’t. Others seem to have had the same.

Perhaps OTA updates (if it was - coincidence if not) don’t update the main SW version reference.

Banbury MG said they had to apply to MG for a SW update(s) to my specific car (and another they had in for the same update(s)) - it’s not something they can do off their own back.

I’d ask your dealer to check what SW version the car has - on the home screen, swipe to the main menu > settings > system. If it’s not R62, ask them to check everything works as it should then, if not, ask them to update to the latest SW version.

Don’t be fobbed off! Hopefully, you’ll have a good dealer like I now have!
