    It seems everyone is trying to deactivate this but I’m trying to understand why mine isn’t working
    Any idea 💡 guys ?

    I’m sure it can be disabled by unplugging a cable in the rear battery cubby.
    There is a video showing how to do this BUT if your battery is low on charge, stop/start doesn’t always function on my car and I presume this is common.

    Video showing how to disable this annoyance is here:

    A previous owner has maybe disconnected it using the method Narpy posted...or disabled it with an IID tool, the option is there in the CCF listing to disable it as well as enabling or disabling the button memory function.

    I put a how to post on the tips and tricks section on enabling the button memory function with an IID tool a day or so ago... https://disco5.co.uk/forum/thread4188.html

    Works fine on the Bling Barge now since it remembers the last selection for the auto stop/start button. I've always switched the damned thing off as soon as I start the car... so it now defaults to that when I start up...saves pressing the button every time.

    Maybe my battery is in permanent low charge (short journeys) because if I have the air con on, the auto stop never kicks in. Only if I’ve been on a longer journey or don’t have aircon switched on, does the car shut down.

    See, I think swmbo has auto climate on always so that could be a reason
    I’ve charged the battery with my ctek so I know it’s good

    Only reason I’m doing all this is because it’s still under five months of warranty so I wanna make sure and check everything before that runs out

    My auto stop/start always seemed to work even when the car was giving the message 'Battery low, please start engine' first thing in the morning...or at least it allowed me to press the stop/start button and disable it. Pressing that button was so built into habit that I still go to switch it off after I start the engine even though it's now off by default after the CCF edit Rolling Eyes

    Not sure how different years of the D5 handle the stop/start. I read somewhere that some models had a second battery, some had a hybrid main battery that handled everything. I know mine only has a single main battery since I've raked around in the battery compartment...if there had been a rogue battery shoved in there, I'd surely have noticed.

    I'd tend to agree that low battery voltage would effect it's operation...although on the occasions I'd forgotten to press the damned button, the auto stop/start would only kick in under certain conditions...like the length of time my foot was on the brake pedal or something?... Since it didn't always stop the engine at junctions, even if I had to bring the car to a complete halt.

    We don't have exotic things like traffic lights...or traffic...or towns up here that the stop/start served any useful purpose anyway. It's just a fuel guzzling, DPF destroying annoyance that kept shutting my engine off when I didn't want it to.

    Besides the annoyance factor and needless battery drain, I hated the thing with a vengeance anyway...hence me searching through the CCF list with an IID tool to find that button memory option and enabling it. Having an IID tool, the CCF edit seemed the best option to me rather than pulling the plug out since the stop/start still works exactly as it's supposed to... except now I have to press the button to enable it rather than the other way round.
