Not sure if this is forum off-topic - interesting/ not interesting?
Certainly very American and a bit manic?
Regardless, might be worth a look - see here: https://www.youtube.com/watch?v=dFImHhNwbJo (https://www.youtube.com/watch?v=dFImHhNwbJo)
Real world experience or comment welcome...

Why wouldn't it be? Sometimes you don't want it but it can be switched off but when you are sitting still you aren't using any fuel or polluting. Win win.

Yes.

DSG and Manual are 2 completely different experiences with stop-start, works better with manual - you can leave it on all the time and just keep your clutch dipped for a brief stop at the lights when you know they're about to change, or at a roundabout. If it's going to be a while, put the car in neutral and let it cut out until you depress the clutch to go again.
DSG is a completely different matter (as I have found iut with my new Polo GTI+ (only comes with DSG currently).
With DSG, letting go of the brake causes the car to restart again after a stop. Annoyingly, when the car in front shuffles more than a few feet forward, your DSG car fires up again. More often than not, the forward movement is just shuffling /bunching up of a queue of traffic going nowhere. You can't reliably feather the brakes to come to a stop without the stop-start cutting off the engine (to wait for a brief stop only), as the stop-start can kick in while the car is (just) rolling to a stop (1-2mph). I end up pressing the stop-start off button to keep the car going if i'm only going to stop briefly. There are savings to be made, but they'll be marginal unless you are regularly gridlocked.

Could stop start disappear with the new MPG and emissions testing? It was only ever introduced I believe to fiddle the mpg and emissions figures by shutting the engine down during parts of the urban cycle. In real world driving it's not practical and a pain for reasons highlighted above.

Not just DSG which has this annoying feature - my 7.5 manual GTI does the same.

I coded it out straight away. I find it annoying at junctions etc, but was also under the impression that hot engines (specifically turbos) don’t like being turned off when hot repeatedly. Maybe a myth, not sure...
-
Why is there not an accessible feature to just switch it on/off permanently?

Yes of course, VW would fit something which would dramatically increase the chances of warranty claims for broken turbos, because that's such a cheap and easy thing to fix that its perfectly offsetting the environmental benefit...

Not on my 7.5 PP dsg it doesn't, it's only when you touch the throttle or the car in front moves. That's one of the things I like about it compared to earlier versions - you don't have to dazzle the drivers behind with your brake lights on.

A warranty is only 3 years long.

Being as every newish car I’ve been in over the last four or five years has had stop start and most have been turbo cars I think the cooling of turbos has been engineered well enough now for it to not reflect reliability.
If anything it’s the batteries that get the hardest time. I have had to have one replaced myself in my GTI PP.
The turbos don’t need warming up or down like in the early days and last a lot longer.
I’m of the opinion that Stop Start is great in manual cars and probably a headache in DSG equipped models.
I think we are stuck with it whatever for a few years until combustion engines slip away into the history books.

Unless you have auto hold on

The worst thing fitted to modern cars imho.
Why do we consumers put up with it?
It should be an option that you can choose or not.
It's just unnatural for me for a car to be constantly shutting down and starting up again and must place unnecessary stress on parts of the car.

But you can choose; you have the option of switching it off. It’s become part of my starting procedure to switch off stop start when I start my engine. I usually only re-activate stop start if I know I’m going to be sitting in stationary traffic for any length of time.

Bought a Kufatec coding interface to disable the stop/start

Throttle blip rather than brake release is probably tied in with the function of the autohold - Polo has old school handbrake which I only put on when parking the car up. The Polo always wants to creep forward when not restrained by the brakes, which is fine with me, but firing itself back up because the car in front has shuffled forward and I have not triggered the restart is by far my biggest annoyance.

If you could disclose the coding pathways via VCDS or OBD11, i'd be most grateful!

Stop start on DSG is a real hinderence ime. Best coded out completely.
Obdeleven coding - Disable stop/start
Select Control unit 19
Adaptation
Stop start limit voltage
Set Value to 12
(default is 7.6)

Coded mine out a week after getting the car 4 years ago and not regretted it at all.

Booth/Wantmygti, thanks!
Ah, I thought from your post that you meant you coded out the restarting of the engine when the car in front shuffles ahead. The only time that trigger could ever come in useful is for someone daydreaming while waiting for the lights to change (as long as you are not the lead car) and save you getting tooted at. If it came to killing off stop-start altogether, i'd probably just press the button at the start of every journey.
What I do at the moment is knock stop-start off when i'm driving around stretches with roundabouts, and put it back on if i've just missed the lights at a junction and will be in for a long wait.
I know the mpg impact isn't huge, but mpg of the Polo GTI+ is a little lower than expectations. My commute is 13 miles now, from 20, due to a new job - so 35mpg Summer expectations on the R would probably be 30mpg expectations on the shorter commute (missus has the R Mon to Fri for her even shorter commute). Until I hit the 620 mile/1000km threshold for opening up, I was getting 40mpg ave in the Polo. Now it's 35mpg with a slightly heavier right foot and very slightly heavier traffic now kids are back at school. Went Newcastle to York and back 2 weekends ago, maintained 80mph most of the way and averaged 43mpg.
