OTA update 19C-19.46.4-458817 possible bug for reading speed

After this update, the speed limit indicator still recognise the various speed limit panels and displays OK for 30,50,70,and 90 Km/hour but displays 100 Km/hour for the 110 km/hour panel and 110Km/hour for the 130 Km/hour panel
Before the update the display was always OK so I strongly suspect a bug on this last update.....

Has anybody also got this problem ???

Does anybody knows where and how to report this to JLR so that they can rectify this bug on the next update or is it too much to hope having JLR listening to their faithfull clients???

Thanks and regards

Serge

Just a thought, but have you a trailer connected? On my 2020 model, when I plug in the trailer 13 pin plug, the speed limits displayed are what the legal limits are for towing a trailer & not the road limit. ie in Uk on a 60 mph limit the speed warning display is 50 mph, (max permitted speed for towing a trailer) but when on road speed limits, ie 30, 40 50 when the trailer speed is irrelevant it displays the correct speed for the road. All clever stuff. current 2015 hse dynamic, grey.

Thanks a lot for this info, I did read some thing about this on the manual but I forgot
I did indeed have a trailer connected by 13 pins plug when I noticed the speed limit discrepancy so this is probably the reason and it is probably not a software bug but as you said it might simply be a clever features from JLR
Another clever feature, in France the speed on motorways is limited to 110 Km/h when it rains instead of 130 Km/h when its dry so when the windshield wipers are on, the car displays 110 Km/h even if the signs say 130 Km/h
I also noticed that the autonomous drive feature (what JLR calls « steering assist«  which works great without trailer) is apparently disabled when the trailer is connected, probably for some technical, legal or regulation reason even though it is not mentioned in the manual
Modern cars are really clever....

Thanks again for your info and best regards

Serge
