Stop/Start not working
Generally speaking I switch off stop/start as soon as I set off as I find it annoying in heavy traffic.
However today I found it wasn't working when switched on. Being a beehive full of knowledge of all things mechanical and electrical I instantly knew what it was - or rather didn't as I have no clue on these things...!!! I switched it on and came to a stop again, and it did not work, so I went into the settings via My Car, went to the sub menu 'Drive' and noticed it said ''battery charging'' and something about ''stop/start will not work when the battery is charging''. I have never seen this before, but then again probably because the battery for the stop/start has never been flat, so obviously wouldn't show!! So I figured I would post for anyone whose stop/start appears to not be working to have a look at this first. So in conclusion its not faulty, its just that the seperate battery for the stop/start needed a charge - which is understandable really as the car has been stood for a couple of weeks Regards |
Yeah I noticed this on my new MY14 about a month ago even after a couple 250/300km runs, message up start/stop unavailable.
Took it to shop but of course it wouldn't do then, it was fully charged and start/stop worked perfectly. Then last week noticed it again plus it won't even play the radio with ignition off, get a battery low message up, so off to dealer again when I get a chance. |

The Main Battery on the stop/start is an AGM flat plate type and they seem more troublesome than the standard calcium silver one fitted to non stop/start cars . It should hold good charge for at least 3 months if all is ok . You MAY need a new main battery depending on the results of the test at your dealer. |

Must admit that the car hasn't been used much in the last few months, standing for a couple of weeks to three weeks at a time, then a few short journeys, then standing again. Doesn't do batteries much good that I suppose. Regards |

The battery will need a long charge on a charger first , use one which is capable of supplying at least 15 or 20 Amps . Overnight is not always enough . and when charging it is Important to put the charger earth to the CHASSIS ( or engine or gearbox ) of the car NOT the negative battery terminal , otherwise the car's battery monitor will not measure the fact that the battery is being charged and it will affect it's calculations . Try it see how it goes , and if it fails again get your dealer to do the onboard battery test proceedure whilst it is not working .. |

Unfortunately I have never had the pleasure of driving a new Volvo. But some silly womans insurance company were nice enough to 'loan' me a 320d M Sport for a couple of months the other year, and although I loved the car, I hated that stupid stop/start system. I actually found myself sitting at the lights with the clutch in all the time so that it wouldn't cut out. I think we drivers are born with an inbuilt fear of 'stalling' it , and it just doesn't feel right when the car does it all on its own.
