I talked to my dad about his stop/start and in the 3000+ miles (all short journeys <10 miles) and 4 months he's had the car the system has worked fine.

 

The only times it hasn't worked is when, has he puts it, "when the automatic choke is on" (fast idle) and when he travels a very short distance <1 mile to Tesco (battery level too low for stop/start?)

 

MarieD, if your stop/start doesn't work most of the time arrange for someone from the dealer to go in the car so you can show them it isn't working.

It's a great selling ploy for the eco types ;)

I turn it off as soon as I get in the car.

There's also the point that the engine has to work that bit harder to put back the energy used to start it so that will be offset against any potential mpg gain. I think the main reason for it is to reduce emissions in city traffic but, again, the extra work to replenish the battery will eat into any emission reduction.

I have the Focus 1.0l ecoboost 2013 and when purchased the salesman was very upfront saying for the stop/start function would only work so long as the engine was warm and the battery was in good condition, fully charged and little drain on it. I.e lights air- con heated windscreen etc. My own experience is that this function works every time even after a journey of 4 or so miles say when I travel home in the evening in the dark with lights and radio on. The way it works for me is stop the car, put it in neutral, release the clutch and apply the handbrake, the car then stops, to restart dip the clutch the engine re-starts.

Try a hard pump on the break pedal when stopped in natural. It has activated it for me before!

As said above it won't work with heated screens on, cold engine and low battery.

Hope this helps

Thanks everyone for replies. Reply from rossbclarke particularly helpful. - rather than the brake though, I have been hitting clutch when stopped and in neutral  ( and pushing it right back to floor) and Autostart then seems to be work fine!!!  (I must have been too light on clutch up to now??). Anyway that seems to have worked great over past few days, so back to being a hapy Ford driver again. Thanks all

Hi folks

 

My stop start has not worked since the aa fitted a varta battery (mine started leaking at a seam) (cracked plastic at the seam)

 

My ford dealer says that its the wrong battery and even resetting the stop start system it still doesent work

 

Ford recomend a Motorcraft Flooded Cell Battery whatever that means, for the system to work

 

Jamie

Important to remember too that another advantage of things like stop start is that if gives tax reductions, often to the point of zero tax. Of course the question is if the annual tax saving plus any fuel savings are worthwhile given higher purchase costs usually associated with "green" cars, and any additional maintenance for the system (wonder what it does for batteries and starter motors life?)

batteries are special AGM gel batteries with a smaller battery, some start/stop systems use the starter to start the engine and others use the altenator as the starter.

there is no extra maintenance for the system. we have a customer who has clocked 50,000+ miles in his 3.0 diesel XF which is 1 year old and it hasnt failed yet

We are also having problems with the stop start.  Although if often doesn't stop, the infuriating one is that it occasionally doesn't restart when the clutch is pressed and you get hooted at by the cars behind you at traffic lights.  There can also be periods when the engine does not switch off at traffic lights despite the battery obviously being fully charged & all the other criterior met.  The dealer can't find the problem & tells you that there is no fault logged.  I suspect it is either the clutch pedal switch or gear neutral switch being intermittent (MarieD's problem seems to be the gear neutral switch as jiggling it got the system to work).  I suspect the dealers have got brainwashed by the diagnostics & can't deal with problems arising from simple on/off (or badly adjusted) switches that can't be found by the diagnostics.

With stop/stop referrig to batteries. The batter state of charge has to be over 80% yet the battery voktage can be perfectly ok say 12.4volts for example the state of charge could only be 60% causing the stoo/start to fail.

This normally happens on cara that does a rugular short mile trips. But taking it on a long trip wont bring the state of charge over 80% it has to be done for a few days.
With stop start you have to meet a silly ammount of criterua for it to work.

Cant remeber the list but its things like;

Fuel level over a certian ammount (no light on)
No eml on etc.
Seatbelts plugged in (if people are sitting in the seats)
Car in nuetral
Handbrake on
Battery condition (state of charge)
And engine temprature

Not 100% if there is more. I work with fords day in day out an there isnt anythin clear enough in the litrature about the state of charge an why the battery voltage can be good an the state of charge is too low. They all say its the smart charge system on the alternator doing its job. An theres certian thing you have to do to get a good state of charge

Im not sayin the smart charge is faulty if the state of charge is low. Could simply be down to communting miles etc

Thanks.  Although the car is mainly used for short journeys the stop start does work often.  The point I was making was that as it sometimes won't restart after stopping, then there must be a fault & it's probably the clutch switch.  If the clutch switch is faulty then it will probably occassionally not stop.
