F type

[Philis46]

Hi I recently bought a Ftype 3.0 v6 2020 but stop start won’t work I just have the logo pop up with a line through it. I have plugged in the switch in the boot that had been unplugged and also fitted a new battery. 
any ideas what it could be. 
manny thanks

Hi Phil, the stop - start function will only work if the car's brain knows it has sufficient charge. Even the fitting of a new battery may not be sufficient yet for the brain to accept stop - start functionality. Are you primarily doing short journeys?

If you don't already have one, I suggest you procure a suitable Battery Conditioner such as a Ring Automotive RSC612 Smart Charger or the CTEK MXS5 Battery Conditioner - my preference is the Ring Automotive unit, but both will work.

The Ring version has a LCD screen which gives a lot of information during use, plus it has multiple functions to condition and test the battery.

Thank you yes it’s on CeTeck charger with another bluetooth monitor to my phone the battery is at 100 percent. I have 3 bikes all on optimate chargers. I just thought once I plugged the lead in it that the previous owner disconnected it would come back on.

Hi Phil

"Hi I recently bought a Ftype 3.0 v6 2020 but stop start won’t work I just have the logo pop up with a line through it."

When you get that on the dashboard it means that Stop/Start is disabled. At each start-up the system should be re-activated unless you press the Eco button to disable it again, at which point the sign on the dash comes up to say it is disabled.

As Jim said it is possible that, assuming you have not used a code reader to "tell the car" about the new battery that it has not yet realised 🙂

I know with the XF that every few months the car performs a battery test to confirm its status. Until the car does this it might simply be that it is not sure that the battery is able to complete a "start" so does not initiate a "stop".

For me the Stop/Start light being on is important. If this comes on without you pressing the button there may well be a fault. You say you recently bought the car? If not a private sale I would be heading back to the dealer for them to sort it....
