Start stop not working!!

[Focusfreak]

 I have a 2014 mk 7.5 ecoboost Fiesta

start stop was working fine but noticed the other day it stopped and the switch in front of the gear lever turns yellow when I start the car indicating is off and does nothing when I push it to turn on, new battery was fitted a week ago and was working fine, any ideas please would be appreciated.

Oh no !!! there goes the poor dolphins again.

I can't remember if anyone has had a problem on the forum with Stop/Start before...............

Just did a quick search on the forum and it seems it's been mentioned in nearly five thousand threads !!
