KER’s level 3 braking failure

[Mark Holmes]

Just had a warning come up on my dash to say that the KER’s level 3 isn’t working as it should and to use the pedal, has anyone else had this issue it’s been working fine for one whole week...will call MG tomorrow and get it booked in. The message doesn’t appear on level 1 or 2!!

Is the car fully charged? other wise nowhere to put the regen!

Mark, Ignore it, it's NOT a fault. When the battery is nearly full the KERS is reduced. Think of it this way if the battery was a pint of beer, you have a sip then top it up back to a pint, don't take a sip and if you try to top it up it again it won't take it, it would overflow. This is why you get the warning. Its just a warning to make sure you brake and NOT rely fully on the KERS slowing you down. The warning ONLY comes on if the user changes the KERS setting manually.

Yes it was fully recharged last night

I have noticed today that it has started working again, noted your comments about the pint of glass analogy, but I’m sure it worked before when it was fully charged?
Has anyone else noticed this issue with the KER’s?

This has happened to me a few times but I ignord the warning and all was fine. One thing I’ve come to realise about the MG is that it pays to carry out each function slowly and wait a second before the next thing I do to give the software time to work out what it needs to do.

It’s seems to only happen when fully charged, however I will monitor for the time and see what happens before going back to MG, hey I have 7 years....

Only when fully charged as there is nowhere for the KERS recovery to go so you don't get the braking effect.

Mine does it as well....nothing to worry about, all OK when you have done a few miles ......then you can save your brake pads again!

Mine did it again today even when not fully charged...
