Absolutely you shouldn't. why would anyone in their right mind consciously, deliberately, needlessly and maliciously decelerate in front of a faster moving car?So I should not decelerate because someone behind me is speeding is that really what you think? I am trying to get out of the way without breaking the speed limit.
I thought this is how it should work anyway, since its impossible to add charge to a battery that's at 100% already? I seem to recall before the update, my KERS wouldn't work either if the battery was at 100%.Today after the update and a charge to 100%, the car has no KERS at all and I need to brake manually until KERS kicks in at around 96%! Added to that the drop from 100% to 96% is much quicker!
Hi, so before the update are you saying that you were able to put the car into kers3?Well I at long last had this recall done yesterday at 1st service. Prior to yesterday my KERS worked even at 100% in the sense that the car slowed when throttle was removed and the needle indicated that the car was recharging the battery. Whether or not any charge was actually going back in I don't know but the car slowed and the meter indicated energy returning to the HV Battery. Also when driving from 100% I could get 4 miles before it got to 99% and the rate of drop to say 95% was fairly slow.
Today after the update and a charge to 100%, the car has no KERS at all and I need to brake manually until KERS kicks in at around 96%! Added to that the drop from 100% to 96% is much quicker!
In short, what a garbage update that has been!
Sounds to me like they have changed the behaviour of the BMS to avoid charging into the buffer at 100% either from the mains or KERS. That's probably a good thing for battery life but less good for range and drivability.Well I at long last had this recall done yesterday at 1st service.

Mine goes into KERS3 at all battery levels - before and after this update. Sometimes the regen feels less, usually when battery full or perhaps when cold - but display always shows '3' when I select it.Hi, so before the update are you saying that you were able to put the car into kers3?
Kers2 will give some regen.
Mine will only go into kers3 at about 95/96%.
I think what I’m finding is that after a load balance charge I can put it into Kers3 at 100%. But if I just do a charge to 100% without leaving it on to balance I get the same message as you when I try to put it in Kers3. At about 98% I can do it. So is it something to do with balancing the battery?I’ve never been able to put the car into KERS 3 until I’m down to 98% or less, if I try at 100 or 99% I get a message saying something like regenerative braking mode isn’t available. MG5 SR and had the update done the end of last year.
Yes, it is possible that if the battery pack isn't balanced then one cell could be 'high' and the BMS would prevent KERS as it could otherwise overcharge the high cell. Balance or Equalisation Charges are a really important part of EV ownership not just to prolong the life of the battery but also to ensure you get the full driving range.I think what I’m finding is that after a load balance charge I can put it into Kers3 at 100%.

I'm not sure you've posted on the best thread for your comment on OTA Updates, but it is perhaps worth noting that OTAs are not all equal for all car makers. Some ie Tesla can provide OTA to pretty much any and every software system on the car whereas others are far more limited in what they can or will do and can be just the infotainment system and no more.I'd much prefer dealer updates than OTAs. Check out a YouTube video by Chris in Battery Life when he had to update his VW ID3. It looked as if the car was unable to be driven for hours (not that I'm going to watch it again).
