Have you been runing the air con as well? That, I think, prevents the stop/start system operating.My dealer didn’t see it in action on his diesel version but only on the petrol. So I was hopping it’s a diesel issue which will be fix with a software update.
I’m in Corsica, pretty high temperature since I got my hands on mine. May be that’s why. The owner manual states that the ESS automatically disengage if exterior temperature is too high…
I can't recall ever turning the AC off in my vehicles over the last 40 years
Mines doesn’t work either on my diesal. Had it for three months, battery charged and the stop/start has never kicked in. Time it need a software update, what’s taking them so long?
I need to try this. My aircon is always on auto. So if I turn off the aircon, the stop start should work. That’s odd, I had a BMW X5 3d and the start/start would always work whether the aircon is off/on.
AC compressor should be electrically run on modern engines (especially BMW) so should be able to still run when start/stop activates. Battery charge and heat load will affect this.
Just bridge out the contacts at the back of the switch or add a relay that switches it off at start
Yes. I’ve tried to turn off the A/C : no joy…
It’s a diesel to ?
Agreed, our X3 will restart when it needs to, sometimes after a minute or two, other times after a few seconds.
Except in Launceston
