you know you will only be stopping briefly and do not want the engine to cut out then use a light pedal pressure on the brake,

This would be ok for short periods but this will wear the clutches as they remain engaged. Once the handbrake is engaged the clutches disengage as well.

Hybrids only benefit from the feature. I was always told most engine wear is suffered when starting. The bearings and crankshaft must suffer when the oil stops circulating. Even Castrol has jumped on the bandwagon with stop/start oil. Interesting to see what stop/start engines are like after 10 years service.

As soon as you come to a standstill the handbrake comes on automatically.

Are you sure? Autohold and parking brake work differently and autohold only comes on if you exceed a certain brake pressure while stood.

Yeah parking break comes on when u switch ignition off. Autohold basically holds your brakes, holds with hydraulic pressure.

I agree with this in part - the oil doesn't normally have long enough to 'completely' drain away from the bearings & crankshaft on the length of time that S/S usually has turned the engine off for! (Apparently)

 

For me, it's the safety aspect of eyeing up a space in some traffic and then your darn car won't go as the ruddy thing is OFF....... Grrrrrrrrrrrrrr (The power steering not working the last couple of seconds when coming to a halt i.e. S/S has kicked in before the vehicle is actually stationary is a total PITA too!)

I think the clutches disengage when the auto hold is engaged as I see the revs rise.

I really don't see this (220 DSG) -- with stop/start enabled (by default), in the time between me lifting my foot off the brake pedal and moving it to the accelerator the engine restarts, the fact it was off when my foot was on the brake is irrelevant.

 

Unless you're using autobrake (not stop/start) in which case the engine doesn't restart until you press the accelerator, then there is definitely a delay -- so don't use autobrake, it's off by default anyway.

 

Or you're using left-foot braking to shave every last tenth of a second off the launch time, but most people don't do this...

I think this is personal preference. Some people like it some dont.  I use autobrake but stop start is coded out. Again this is how i prefer it. Odd odd times, if in a traffic jam on a motorway it could be useful. 

 

So for people who like it carry on and those that dont, theb maybe coding it out is the way to go. 

I coded it out the day I bought the car! I have it on my work van and every time I get in it I turn it off, it’s 2nd nature now! When I got the van (my 1st experience of stop/start) I thought it seemed like a good idea. In actual use though I found I’d get to a set of lights and the engine would stop, then about 1 second later the lights change and I’m off again. Also in the summer I want my a/c working to full effect and same goes for the heating in the winter. For these reasons I came to the conclusion it’s a gimmick and I don’t use it. I think it’s just another way the manufacturers fiddle their mpg & emissions data and the feature offers little benefit to the driver. How much fuel would you really save anyway? You wouldn’t even notice it over a tank I’d say. 

^^^ It is not about saving fuel for you, it is about dozens or hundreds of vehicles all sitting idling in gridlock traffic with the emissions being emitted.

If you are not in that driving situation then obviously stop / start does not apply to you.

But if you are sitting stationary it is not just other drivers about there are people not in vehicles being affected by the emissions.

 

The solution would be New Technology and where stop / start is disabled the tail pipe emissions go right into the vehicles cabin.

WOW! To be fair I’m all for saving the environment. If I find myself in a traffic jam I just resort to the old fashioned method and switch the engine off manually!

I bet you are popular in places where you add to the slow traffic!

 

He knows his stuff, but if you are driving through Glasgow, Edinburgh or Aberdeen and 10 miles takes you an hour and everyone else as well you soon know how much is being spewed out.  You can also see one day how much fuel you use with Stop / Start functioning and another day with it 'off'.

 

Obviously no issues with every taxi, or car waiting to pick up kids from school etc sitting ticking over.

No miles per gallon actually being done, but then 'No emissions' for anyone to worry about.

But we will see as Local Authorities bring in 'No Idling' by laws. These are being done now in areas with high pollution and where there are to be Low Emission zones.

Ok I’m confused. Which side of the fence are you? You seem to be saying stop/start is the best thing since sliced bread but the video seems to suggest it’s a waste of time?

It has its place and time. 

 Stop / Start, Autohold, e-brakes and Hill Hold Assist are great things, except where a Manual Parking brake can be so useful and missed. Winter etc, actual offroad / off tar.

 

I switch it on and off depending where i am over a journey, eg doing the first junction 30 feet from my house.

if it is functioning just as i getting to junctions and not stopping or giving way i hit Off or stick the A/C on.

(making sure the Stop / start does not function, 

the A/C button being handier than the Stop / Start on many Right hand drive cars / vans.)

But there are differences from car to car and when you are driving others cars or people driving yours 'Inhibiting' Stop / Start or Coding out is not always the thing to do.

 

Its like using your Full or Dipped beam, wipers, Fog Light, Heater or Radio, have it available if needed, because 'turning off the engine; is simply not doing the same as Stop/ Start being enabled.

People with Stop Start can tun off the cars ignition as well if they want all off.

Each to their own I guess but for something that I so rarely find useful all that switching on and off seems like an inconvenience, especially in a car that is all about making the driving experience as stress free as possible. As for other drivers it’s my car so I’ll have it how I want it and coding it out works best for me. As others have said if you could reverse the operation of the switch, or just make it so it doesn’t default to on every time you restart the car then coding wouldn’t be necessary. 

 

The only scenario where I could see it being useful is traffic where you are like move forward, stop for 30 seconds, repeat. I don’t encounter this kind of traffic often (ever?). It’s more like move forward, stop 3 seconds move forward. Even if I did I would be concerned about the wear and tear due to all that stopping and starting. 

To slightly contradict my posts above, my sister has a 1.5 petrol Octavia and when I’ve driven it I haven’t been irritated by the stop start like I have in other cars. Perhaps start stop is well suited to petrol & manual. The engine starts super quick and to be honest is so quiet you don’t always notice that it’s cut out. 

IMO well suited to 2.0 TDI SCR DSG Euro 6 engines and if not seemless then there is something wrong with the car or user.

My better half’s Fiesta, petrol with a manual box had it and I never had an issue with it. It cut off once the car wast actually stopped and by the time I had depressed the clutch and selected a gear it was good to go. The system on my car could be good in theory. but it’s a bit pants in reality.

Hmm. A joke? Or trolling...on a Skoda forum? Haha

I have a 2.0 TDI SCR DSG 2016 SEAT, and have a Skoda.

Another point; petrol engines (like mine) tend to start and stop more quickly and unobtrusively (with less noise and judder) than diesels.

I just switch it off as a matter of course as part of my start up procedure , just like every other stop/start specified car I've owned ... my OCD tendancies are a great help mind you

In my experience of stop/start in a manual, the engine only cuts out when you put the car in neutral and let the clutch out. With a DSG, it cuts out every time you (almost) come to a stop, which is a real PITA IMO 

Agreed. The dealer who sold me the car said exactly the same thing and turned it off for the test drive.
