stop start and battery advice on a Ford
The stop start function on the wife's focus has stopped working.
Dealer is saying battery has had it. Looking at the internet it suggests having a dealer fit a new battery as diy can lead to electronic problems, what do you know of this? Also, if the car starts ok, she drives to the shops, she stops the car does what ever then starts it again and drives to next shop and so on and each time the car starts why does the stop start not stop? Surly there is enough guts in the battery to start the car as the wife is able to start it. confused wit nagging doubt that battery is duff but it could be due to only knowing about old type of technology macafee2 |

Personally I think you are better off without it.---Can't see it being the battery if the engine starts OK. |

Stop Start
Have a similar function on one of my cars, and with doing short journeys, it tends to drain the stop/start, but I use a CTEC charger on mine, once a month, charge it for 24 hours, and stop/start starts working again, so would suggest that you maybe invest in a ctec charger, best bit of kit I have purchased, as I also use it on my other cars and keeps batteries in tip top condition. got mine from a local company, but you can get them from a variety of places

Why not just disable the stop start function?
There's a button on the dashboard of our Fiesta and BMW. |

On a lot of these unfortunate cars, it's very difficult... my mechanic is very clued up on such things, but from what I remember it took him many months of research to disable it on an MG6. I think he had to hack the ECM

The dealer is most probably correct-the various ECU’s involved will have a set number of pre-conditions to engage the stop start function (state of battery charge, coolant temperature, cabin temperature & air conditioning load etc) and if these aren’t met then it won’t function.
Doesn’t take much of a voltage drop of the main starter battery to fall outside of these conditions, but still being able to start the car on a twist of the key. The advice above of investing in a CTEK or similar battery conditioner is good. It’s not “made for main dealers to make money”; it’s one of the many things manufacturers are doing to try and drive down the CO2 emissions and thus tax a car attracts. |

The moment the engine is running there WILL BE 14 volts plus in the cars electrical system.--- Don't tell me that won't enable the system immediately. CO2 saving you say. Think of that rubbish next time you stop behind a lorry or look up into the sky to a monstrous passenger plane flying by over your head.------Zillions of CO2 dropping straight down on top of you and your family, if you have one.---It's a con and it DOES make money for the dealers in replacement spare parts and batteries etc. You, my man, have successfully been conned.--They've got you, hook line and sinker.----- Now go stand in the corner and repeat to yourself---I will try not to believe everything I'm told in future without first having a good think about it. Nobody it going to tell you their system is rubbish, and in addition to buying the car you are going to have to buy a charger cos their invention can't cope on its own.--( see an earlier post. ) |
