Stop/start Doing Your Head In? Disabling It - How We Done It -

Do you have a link?
Here you go.


Just plugged in and it worked. Not had to program it.

Sweet, thank you. And that memorises that it's off when you turn engine on
 
Would you need to remove one of these modules before presenting the van for MOT? E.g. if the Auto start/stop is automatically switched off every time the ignition is turned on, would this be highlighted and fail an MOT?

I’ll tell you in the 1st December when it goes for its first one. If you programme it to deactivate they wouldn’t know. Stop start might not activate if battery is low so I doubt they would care.
 
No start stop is not part of an MOT test.

And you can disable the unit for a while, then back to normal by pressing and holding the button.

So our can be switched on/off as you like
 
This is everything that's wrong with the world. A genuine attempt to reduce emissions and improve air quality for all of us and at no inconvenience or cost to the driver.

But because people simply find it annoying, they choose to disable it.

Those same people will expect help when they call for it, but have no interest in helping others.
You absolute P enis
 
Well you might save 2 or 3ml of diesel each stop/start cycle - lets say 5ml.
30 stop/starts per day = 150ml per day
Lets say 1 litre a week. (50 litres a year to stay friends and not argue about niggling numbers)
Lets say the battery life reduces by 2 years if you use stop/start, and battery life would expect 5 years (haha). Lets say the same with the starter motor last 10 years but using stop/start reduces it to 5 years (an extra 10,000 starts a year).
Over 10 years, it costs 4/5 of a battery and 1/2 of a starter motor.
A battery supplied/fitted costs about £250 at a guess
A starter motor supplied + fitted - at a guess about £750.
500 litres of diesel saved = about £800 - lets say about £1000 after price rises over 10 years etc.

Pricewise with the above very rough calculations it won't make that much difference walletwise. However, emissions and materials related - what do you think costs more environmentally - 500 litres of diesel or a battery + starter motor.
Personally I think there isn't much in it - the sulphuric acid industry is horrific. The plastics industries are horrific. The metals/smelting/mining industries, guess what - horrific. Oil drilling/pipelining/shipping/burning - yes, horrific.
If you have a bloody van in the first place, I don't think anyone is in a position to be all high and mighty about what constitutes pollution.

Just my humble opinion.
 
The tiny amount of fuel saved is about the only gain.

In actual use on the highway rather than controlled conditions on a dyno that starting and restarting is less efficient,in CO2, NOx and particulates, than simply letting a hot and efficient engine idle for a minute or so.

It is solely done as a wheeze to gain slight advantage with emissions ratings for each model rather than as a genuine attempt to reduce real-world emissions. For that reason its the one EMCON device I personally have no issue with people disabling if they so choose. SS doesn't bother me, but if people want to fit this device then all power to them.

I was just about to say that ;)

None of this is true, not in my case anyway.

Maybe for a transporter as they seem the mechanical runt of the family, but I would have assumed my Golf is essentially the same engine and components (a 2.0tdi 150bhp) with stop/start.
I’ve owned it from new and it’s very nearly 10 years old. 111k miles on the clock now. The stop/start has always been left to do it’s own thing except if I forget my gloves in winter when I’ll overuse it until the heating warms the cabin.

I’m still on the original battery and starter.

Meanwhile if we look for fuel savings (this should be measurable in theory) we see figures between 5% and 7% from reputable sources. I don’t count the litres Input in but increasing my fuel bill annually by 5% would seem wasteful if I have means to not increase it. I’ll be keeping mine as is (only in the car, the T5.1 doesn’t have it despite being the same age).
 
If stop / start saves between 5% and 7% on fuel, the journey must involve a huge amount of time stationary, it'd probably be quicker to walk.
It probably is quicker for many people to walk when you look at average journey distances and times…

From Gov.UK - “In 2022, 26% of trips were under 1 mile, and 71% under 5 miles. These proportions of short trips were broadly consistent with 2021 and in 2019”.

A lot of people make short trips in busy areas - commuting to a local town/city for instance.

Certainly from experience I can beat the neighbours to our local park (0.8 miles away - apparently to far for their dog but I think it’s them that prefer to drive as they also drive half a mile to the shops or piano lessons) by walking and I stayed level with the same car for 8 miles while crossing from one side of the city to the other on my bike. They were keeping up with traffic and made distance between the lights but I’d serenely glide past and they’d take a minute to catch up. It’s this last example that shows the best case for stop/start in terms of fuel saving I imagine. Took an embarrassingly long time for me to cycle that 8 miles so to think how long that car, and every other one in the same traffic, was sat idling.
