Disabling stop start

Not got stop start on my current car but had it in previous one. On that you could go into the infotainment screen and turn it on or off. I assumed it would be the same for other manufacturers but obviously not. Wonder if it’s just to get you to spend more or not?

I've a button to turn it off on my 2021 Citroen
BUT

It resets to default on when ignition is cycled...

It's possible it can be turned off via a, Obd tool...

But mines a work van so can't fiddle
 
It does but sometimes you forget to turn it off and I find it a nuisance when the engine dies then touch the clutch pedal and it fires back up also I don’t like the constant use of the starter motor and battery. The part I’ve fitted has turned the stop start off permanently until you reprogram it to function as normal.

Many people[weasel words] think that long-term use may induce additional wear due to lack of oil lubrication. For the crankshaft bearing half shells and the big end bearings this can translate into frequent high-speed rotary movement before a hydrodynamic film is established. During this phase of boundary lubrication, metal-to-metal contact can occur between the crankshaft surface and the bearing's sliding surface. This was not an issue while the number of engine restarts totaled what was generally understood to be a normal magnitude. However, in a vehicle with a start-stop system this effect can necessitate new technological solutions to avoid premature bearing wear, depending on the driving cycle. Consequently, future engines for start-stop applications need to be designed for 250,000 to 300,000 starts. Traditional bearing shells with aluminum or copper lining show severe wear after only 100,000 cycles.[43][self-published source?]

I'd suggest that unless you spend all your time in heavy town traffic (London taxi?)

That most folks in vehicles with stop start won't notice any impact as MOST folks now treat their car like a mobile phone that needs replacing every two to three years....

Most of folks with campervan/motorhome based vehicles that have stop start are highly unlikely to be sat day in day out city centre traffic..

Bit of a none story IMHO
 
Stop start is there to save the planet and disabling it will result in the death of many dolphins. Get it turned right off. Premature turbo wear, starter and ring gear, battery and associated starter circuit just for a kick off.

Yes I tend to think so to. I have been driving cars with it for years with no issues.
Most of the journeys I do in my Moho don’t involve much stopping and starting anyway, and it only kicks in once the engine is up to temperature.
 
My Nissan has a switch so. when bonnets open its disabled simple matter to losen switch turn it upside down so it appears bonnet is open even when its not theres no bonnet open light

I'm generally a victim of indifference Barring when I set of at idiot o clock in the morning as I usually do for work...
And Citroens management is, insistent that stop start is, more important than getting the engine/heater up to temp OR aircon needing to run to deal with de misting



Poor do that it seems to be more electrics panicking than engine temp related.

On mercs it only comes on when conditions are correct, and for a max of one minute and four times. It only comes on when the engine is up to temperature, and the car has reached the correct temperature inside. If you don’t want to use it, you can simply switch off from a switch on the central consul. I don’t know about fiats my current model does not have it, but the new one will when I get it next year.
 
Different manufacturers must do stop start differently, my Vauxhalls didn’t kick into stop/start until engine was up to temperature. I never bothered to disable it myself as it just seemed to work. I believe though if you switched it off it would stay disabled until you went back in and turned it back on, can’t say for certain as I didn’t use it. 👍

My Astras were the same, conditions had to be right before it was applied. Didn’t bother me in the car I was much more put out by having an electronic handbrake lol. It’s just not right setting off with a handbrake on 😂😂😂
 
The one I have on my new Honda scooter is like magic. I didn't like the idea as I assumed it would wear the starter motor and battery but I don't think it has a starter motor. It just purrs into life, no starter motor noise at all. You can turn it off of course on a simple switch.

And the teeth on the flywheel get eaten, plus starters give up the ghost, just more cr-p to go wrong, you can turn it off from the ODB port, they all do here.

Dynostart, old school but works, think the susi gt 125 or 185 had it.
 
The manufacturers have to achieve increasing fuel economy year on year. Stop-start was one easy saving along with ditching the spare wheel.
I heard a statistic the other day that one in four new vehicles now being sold can be plugged in, ranging from full electric down to partial hybrid.
 
I have this system on my VW Golf SV TDi, it`s very simple and has become automatic now to hit the button at the side of the gear stick and turn it off.

However, the option is still there if needed and once a week it gets turned back on at the bloody roadworks going to Blackpool that has 4 way temporary traffic lights that have been there for ever and take flipping ages to go through the whole sequence 🤬

As sure as eggs are eggs the damned things turn to red just as we approach so i hit the button and it turns itself off rather than keep using the key then once they change it automatically starts the engine and i hit the button again to disable it once moving and all is good.
 
Don't mind stop start but would.love to be able to permanently switch off the bloody Lane Assist thingy on my Citroen (car) which tweaks the steering wheel annoyingly if the system judges you to be too close to the edge of the road or the centre line. It's a nightmare on narrow country lanes where I do lots of driving. It has a hard to reach off switch behind the steering wheel near the driver's right knee but it needs switching off on every journey. I've asked Citroen to disable it but they say "not possible". Any practical ideas?
