iantt Posted June 25, 2016 Share Posted June 25, 2016 tcm recall is an update to tcm to trigger dtc and mil light if in the unlikely event of a serious module failure , so any mileage/consumption issues should be a coincidence . Quote Link to comment Share on other sites More sharing options...

The new battery should be fully charged now but S/S is still not working. It was a warm day. Did you have your aircon on? If so, what temp did you set it to?

Costing you £150 per year or perhaps more (on 5k miles / yr & £1.10 per litre). How are you measuring it: brim to brim fills, using the pump litre count & the trip mile-meter, or using the possibly dodgy guesses of an in-car display? If that mpg is accurate, (& ideally provable using fuel receipts) I would definitely take it back & complain. Worth the hassle for £150 per year. (A brief drop in mpg after some service operation may be due to the pcm re-learning optimum settings, but that should be just a few journeys, a lot less than a tank full.) Yeah I've been using brim to brim fills with an app to track cost, litres etc and that gives me around 37mpg so probably just a dodgy display readout. 1 Quote Link to comment Share on other sites More sharing options...

It was raining most of the way (20mph on the M1 type of rain) and not particularly warm. Quote Link to comment Share on other sites More sharing options...
Bobr Posted June 26, 2016 Share Posted June 26, 2016 This morning, stone cold engine and S/S is working. Wonder how long for. Quote Link to comment Share on other sites More sharing options...
iantt Posted June 26, 2016 Share Posted June 26, 2016 im not saying any of the below are the reason why your particular vehicles stop start is not working as intended, you do have an issue that needs investigating. but for reference to everyone with stop start, the following can stop stop/start low coolant temp, low battery charge,heated front screen, heated rear screen, aircon (climate control versions),wipers on fast setting , drivers seatbelt not fastened, dpf regen on a diesel version and obviously door opened lol and all these sensors/switches need to be functioning correctly for stop start brake booster vacuum sensor, battery monitoring sensor,outside temp sensor,clutch pedal position sensor,neutral position sensor, voltage stabiliser, and others, given up listing now think you all get the idea now, 1 Quote Link to comment Share on other sites More sharing options...
Bobr Posted June 26, 2016 Share Posted June 26, 2016 Cheers Ian. It didn't last long as I've just driven to the shops and it's not working again. Quote Link to comment Share on other sites More sharing options...
Bobr Posted July 11, 2016 Share Posted July 11, 2016 Took my car in this morning and Fords want it for 5 days to try to sort out the S/S problem. Believe it or not, it was working all the way to the garage. It seems to work when it's cold and raining but not otherwise. The guy on the desk said that they have nothing but trouble with S/S systems. Quote Link to comment Share on other sites More sharing options...
Bobr Posted July 13, 2016 Share Posted July 13, 2016 Had a call from Sandicliffe today. The suspect the battery monitoring thingy. Apparently if it's not working properly it can tell the S/S system that the battery is flat. They are fitting a new one tomorrow. The car they've lent me is a 2012 1.25 litre that has a 2015 plate. ??? 1 Quote Link to comment Share on other sites More sharing options...
elanmac Posted July 14, 2016 Share Posted July 14, 2016 Why do you want the s/s to work? It doesn't make the car more economical, but it surely must wear our the starter motor and ring. I Found that the difference between using it or not was 1 mpg. I now switch it off every time I get into the car. Mac Quote Link to comment Share on other sites More sharing options...
Rockhopper Posted July 14, 2016 Share Posted July 14, 2016 Personally I'd be happy to save 1 mpg if i could. Quote Link to comment Share on other sites More sharing options...

Bosch recommend using a slightly beefed up starter and alternator for Stop-Start. Not surprising as they make the things, but very reasonable. Did the bods at Ford listen to the wise words from Bosch: I am sure the design department did, but the accounts department ??? Assuming the design department won, it makes sense to use the system while it works, but if it starts playing up just because the battery is approaching what would normally be 50% of its lifespan, then ignore it or turn it off. That 1mpg is no way worth chucking out a very expensive battery when 50% life remains. And that argument applies to environmental cost, as much as to pounds & pence cost. 1 Quote Link to comment Share on other sites More sharing options...
Bobr Posted July 15, 2016 Share Posted July 15, 2016 Well they've fitted the battery monitor and are confident that it has cured the problem. They are road testing it this afternoon and I'm collecting it in the morning. Quote Link to comment Share on other sites More sharing options...
Bobr Posted July 16, 2016 Share Posted July 16, 2016 Collected my car this morning and, having had a new battery monitor fitted, the stop / start is now working perfectly. As a matter of interest, I switched the air con on and the S/S didn't work. Switched the air con off and the S/S was back. 1 Quote Link to comment Share on other sites More sharing options...
Bobr Posted July 16, 2016 Share Posted July 16, 2016 Found another quirk with the S/S system this morning. If you reverse and then stop it doesn't work. Pull forward a few inches and it does work. Quote Link to comment Share on other sites More sharing options...

If you only use A/C on long journeys, fair enough but if you need it when the weather is nice it's a shame you can't have both. Quote Link to comment Share on other sites More sharing options...
alexp999 Posted July 16, 2016 Share Posted July 16, 2016 It can activate with AC on, but it is just less likely It depends on the AC load as to whether or not it can stop the engine. 1 Quote Link to comment Share on other sites More sharing options...

There seems to be many factors as to when it operates, we might as well just say it has a mind of its own. 1 Quote Link to comment Share on other sites More sharing options...

I've used the car a lot in town today and it's worked every time. When it turns the engine off the fan is still working. My car has a switch on the dash that you can switch S/S off with. 1 Quote Link to comment Share on other sites More sharing options...

I find it alarming when it has switched itself off in traffic and then after a minute or so, it switches itself back on again to try and maintain your selected a/c temperature.

Bobr Posted July 17, 2016 Share Posted July 17, 2016 Strange that; mine will never turn off with the air con switched on. Quote Link to comment Share on other sites More sharing options...
Rob2016 Posted July 22, 2016 Author Share Posted July 22, 2016 So my car went back to the garage to have the stop / start looked at. They checked all the systems, sensors and updated the software. battery was also checked and all came back fine. Still no stop / start. Car going back to the garage on Tuesday (No courtesy car available today) for more tests and an overnight charge even though the battery they say is fine. Will update.
