The yellow brake dash warning light on my Nissan Leaf is permanently on. (NOT the red brake warning light) The owner's manual says
'it functions for both the regenerative brake and the electronically driven intelligent brake system'
There has been no change to the braking since it came on.

The error code says 'Pwr Supply Backup Unit Comm error'

I have it booked in with Nissan to be checked but the earliest they can do it is in 4 weeks time. The MOT is due next week.

Will it fail the MOT because of this warning light?

Many thanks
