I still have the problem in November 2018. Been in the garage several times. Diagnoses was that it is fixed. Obviously not road tested. Low 12V battery warning again after only a few days parked up. Lost faith in local Skoda garage. Car still in warranty and is being checked again  on Wednesday. A year ago I was told it was too cold for the Stop/Start to work.

The car does have to be at a decent running temperature for the stop-start to kick in, though, so surly there is some sense in that?

On my 2017 vRS, the car info screen can give the exact reason the stop start has declined to operate or has decided to restart, do the older models not give this info? That would surely help figure it out, as some of the reasons reported you wouldn't necessarily expect. As an example, it once reported it hadn't activated as the incline I was on was too steep. It also references loads requested, humidity levels, risk of humidity, etc. 

 

Whenever the little symbol with a line through it appears on the dash, the menu on the main screen will be able to provide a reason why.

No. Mine will sometimes operate within a couple of minutes after starting from cold

But the temperature of the engine is partly dependent on the air temperature. And petrols warm up quicker than diesels, too, so that can be another factor. 

 

Granted im not talking about a VAG engine at the moment but I know that in the winter it takes longer for my start/stop to begin kicking in than it does in the summer. 

My stop / start works 30 feet from pulling away from the kerb and stopping at the junction having just defrosted the car at around 0*oC or lower.

& that is a VW Group Diesel.

Fair enough, but that hasn't been my experience in my current car. Perhaps Nissan's systems run differently.

There are Skoda, VW, Seat & Audi that work different, engines and battery sizes are different and Euro 5 or 6 and now Euro 6d temp. 

That's true, which means that your experience of your VAG engine doesn't make any guarantees for anyone else's (different) VAG engine.

^^^ Nail on the head! 

& neither does a Nissan mean anything as they are different as well across the ranges and age.

Had experience of Stop/Start systems in BMW, Kia, Seat, Nissan and now Skoda (Superb and Fabia).

 

BMW worked pretty much as you would expect until a very cold winter when it did not work for a couple of months. Went in for service and was told battery was getting weak but it still under warranty. A FREE new battery was fitted and the stop/start worked normally again.

 

Kia was pretty flaky to say the least but that is what a majority of owners report.

 

Seat was exactly like the BMW but no battery issues.

 

The Nissan must have been programmed by the same chap who worked at Kia. Even in summer it only worked probably 10% of the time. Most owners report exactly the same.

 

So far the Superb and Fabia have worked exactly as expected.

 

But I never bothered taking the Kia and Nissan back simply because stop/start only saves a thimble full of fuel once a blue moon. Providing the car starts when I want to use it I am happy.

So my my16 scout 184:

if you hunt through to the third ‘car’ page on the multifunction screen, has a little i button which brings up the auto stop start operational status. 

This week it had one journey where it insisted the load was high when it wasn’t, and just refused to turn off. Next journey all back to normal. It also requires the engine temp to be off the cold position on the guage. Anything like heating or cooling demand stops it operating. 

 

If the system believes it is faulty, then the brief touch starting doesn’t work, you have to hold the key. 

If the system just thinks a condition is met to prevent it, the list should tell you what condition isn’t met. It would be helpful to know what is on that screen.

Mine fails to activate if I've set the target cabin temperature too high against what it actually is. Sat in traffic, I can slowly reduce the target cabin temperature then the engine will cut out. That's after half a mile.

Garage report that there is a slight current drain in the tow bar wiring. Wonder if this will be their get -out when  I pick the car up later on. The towbar wiring was independently fitted and uses the expensive loom to integrate the stabilty system etc.

And yes, I will get the towbar firm to check.

We'll see.

Pre-emption

Towbar firm disconnected all their fuses, but left the programmed module powered, If I understood correctly.  And no, the Stop/Start still does not work.

What message is the infotainment giving you when it's not working? If you cycle through the Car information screens as scj103 suggests, the 'Vehicle Status' page will have the stop start symbol with the word 'info' overlaid - if you press this, it will give you the reason the car has elected to stop it working  - knowing what message it's giving you will help in trying to find the issue. It may simply say 'Error: start-stop system', which doesn't give much in the way of a clue but if it's simply not activating, then these messages will point you in the right direction. As said previously, it can choose not to for various reasons - high internal humidity, potential for high humidity, high power draw, temperatures not within acceptable parameters, incline too steep etc.

As always, High power consumption. 

Of course I did try switching everything off. Again. 

But  the loan cars (Fabia and Karoq) Stop/Start worked fine in the same weather conditions.

This is exactly what I was getting at before and has been my experience of stop-start.

 

Although it does seem the OP is experiencing a different issue.

im new to skoda but i do love to see if i can help. told yer just cannot help it, may be wrong 

 

my octavia 1.6 tdi stop start does not work until the engine as warmed up to a pre determined temperature. and i get the icon on the dash telling me its not ready.

I may be worth asking the dealer to check and make sure the temp sensor is working correctly as i am sure it will be considered by the ecu during driving and if it is not giving correct temp reading it will have a knock on effect with start stop and possible other issues logged within the system but not flashed up on dash.

worth mentioning. yes and i know they use computers to read the system but sometime like others have said power power from battrey can cause problems which cannot be solved until you try a known good battery.
