Disable stop/start

Alerium

Hi

I have a 2016 Audi A4 which comes with stop/start technology (most cars do these days). I would like to turn this off i.e When I turn my car on, this feature is off so i dont have to press the button automatically.

Has anyone done this before?

Thanks

Have a look for a button that has A off circled my VW has one and it turns off the stop start function .

That only works for each drive cycle, after you turn the car off and on again, it will revert to on.

If you want to do it for free, you just need to put a fault into the stop start system but you will get an info message on the dash on start-up "stop start unavailable". You could do this by either disconnecting the voltage monitor at the battery or by unplugging the harness from the back of the stop/ start dashboard switch.

If you want to do it a bit more properly you could buy a cheap OBD Bluetooth dongle and change the parameters for it or code it out.

I have the button but after the car is turned off and on again, it just restarts and you need to press the button again.

Sorry my bad I thought you may have only bought the car and didn’t know about the button it took me a few weeks to realise what the button was for when first I got mine but I get what you want to do override the system so it’s permanently off .

As TFB says, you can change the voltage parameters for when the stop/start will become unavailable.
Mine doesn’t cut in unless the battery is above 15 volts.
I.e. never.

Is that difficult? Can any Joe Soap mechanic do it?




Auto stop/start wrecks my head. It's part of my "getting ready to drive" procedure now as standard, keys in ignition, seatbelt, stop/start button.. it's beyond annoying.

Hardly that annoying you'd pay money for is it? We press buttons in our cars all the time
And does a 2016 audi need keys in ignition?

I don't get what people's problem is with it.

It’s easy on VW stuff anyway once you have a suitable device.

It puts more stress on your battery, starter motor and dual mass flywheel. It’s also annoying.

Pull the small connector for the battery monitoring off the negative terminal on the battery.

I just got a VW with it, seems pointless. Slows you pulling from the lights, junctions, unless you remember to drive so that it doesn't get activated etc. Saves minimal amount of fuel. All it really does it stop fumes if you were sitting for a while.

theguzman

It is a pain in the goolies, I have a VW with it for 3 years and it is just second nature to disable the bloody thing each time. All newer cars seem to have it now not just VW.

No it doesn't... I'm surprised at you posting that. Pulling away from a stop puts way more strain on a dmf than flipping a warm engine with a beefed up starter powered by an equally beefed up battery ever would. I use mine all the time.

wonski

Isn't there a separate starter motor for this system?

I am sure there is. The battery is also ready for this and if there is not enough juice it will stop the system from working anyway.

Also, just press the button and the problem is solved.

One of many buttons we press in the cars every day. I personally see no issue with it. Especially when it is smokey diesel cars sitting in heavy traffic

They can take it, you obviously can't. :pac:

Stop-start usually stalls an engine with the crankshaft in the optimum position for restart, and injector primed ready to fire. All it takes is a tiny poke of the flywheel and a warm engine fires up instantly. It's not hard on the equipment. It also fires the engine back up if the battery drain is heavy, or demands on belt powered systems like having the air-con running.

I think to reduce urban pollution in queues it's worthwhile.

I was wondering what effect does it have on DPF if any.

Which in Urban areas is a big problem. If it were pointless do you think every car manufacturer would install it. Didn't realise Ireland had it's own rolling coalers.

There are about two/three occasions a year I use it where its necessary to switch off. This is typically rural areas pulling onto a main road and you have a lot of traffic i.e. going from zero to 80/100kph traffic.

I suspect the reason the Audi resets after every journey to turn it back on is because of people like you who think its funny to choke pedestrians with fumes idling in traffic.

I've never disabled mine I just let it do its own thing.

Not entirely sure why you think it's funny to polute pedestrians but whatever.

Since I don't have an Audi that's some clever software. Also my car doesn't have stop start, so that's even more impressive.

It's on the OH car and in fast moving urban traffic its too slow to react at junctions and roundabouts. Especially on a short journeys with lots of junctions. You can get around it by lifting off the brake momentarily before the lights change to green, so the engine is up running before you have to move.

I wonder if it's autos with stop start why so many are slow to move off on a green light and junctions around town. I just always assumed they weren't playing attention.

wonski

They are on the phones.

That's why they don't move

DaveyDave

It's really not as big of a nuisance as people let on. Speaking strictly from experience with a VW, it shuts off below 5kph so there's plenty of times where I don't even fully stop and the engine comes back on while rolling. When you're waiting at a junction or roundabout and need to pull out quickly just tap the pedal or force the steering wheel lock to restart the engine as soon as it stops so you're ready to go. If you lightly press the brake when stopping it won't stop the engine, you need to lean your foot on the brake when stopped.

People just need to adapt to driving with it. Yeah there's been times where it's turned off just as I wanted to go but it's not a big deal. I wouldn't be going out of my way to disable it.

It really bugs me when people restart their engine when they're sitting in traffic, the engine will kick on when it's needed to keep the cabin warm, demist windows or the engine isn't at operating temperature so you have no reason to restart the engine.

I don't think I do, though (press buttons in my car all the time). My car has a button stop/start (no key turning) and that's generally the only button i 'have' to press. Everything else has a memory to stay as it was when I last used it (radio on/off, audio volume, lights, display brightness, etc.).

This is the only thing I need to remember to turn off each time. It's such a pointless feature. Anytime it engages, I'm usually ready to go again anyway, so all it does is stop/start immediately which just feels jarring when you're at a junction. Or if I am stopped at a long red light, and I've forgotten to deactivate it, the engine cuts out, and without me touching it, it starts back up again within 20 seconds anyway. I don't see the point.

If I'm sitting in a queue of traffic, or at a drive-through or whatever, I can turn the engine off, myself. It's a frustrating option to have forced on you. I don't see why it can't just be permanently turned off in the menu system.

DaveyDave wrote: »

I find it very annoying.

frozenfrozen

Theres a way on bmw with bimmercode app to make it remember your last choice of on or off

I usually have it off and if I'm coming up to red lights I know will be a while I turn it back on before I stop

I hate when I'm waiting to turn across traffic and the engine turns off

I believe that it allows a lower mpg in the lab conditions, which leads to lower taxation, better corporate social responsibility etc.

It’s the same with the arrow which tells you to change up a gear around 500rpm sooner than you feel is necessary.

It most likely is when the engine comes back on immediately after someone stops. If start stop wasn't available the engine wouldn't have turned off.

This. Start/Stop is almost entirely a "green" marketing exercise rather than anything substantive, but we will tend to buy into that sorta thing because at this stage of the game marketing is a pretty exact science. As you note Start/Stop allows car makers to tweak their figures so they appear more green and get more allowances and sell more cars to the public. It's a more acceptable cheat than what the German brands were doing with their cheating of emissions tests. As for saving money on fuel? In 2015 this well regarded crowd did a study into this; pdf here. Lots to wade through, but the upshot was this: If you do start/stop 20 times a day for 3 minutes it'll actually use more fuel(which leads to more fumes for those concerned about that). More start/stops of shorter duration = more fuel. Fewer start/stops say 5-10 of longer duration over 5 minutes = less fuel. However even here the difference is absolutely miniscule. Even under ideal conditions of fewer start/stops of longer duration you're talking a couple of cents per day. Set against that is an undeniable increase in engine wear, more for diesels and autos which have more internal resistance to overcome on startup.

It's a "feature" that's more in the minds of marketeers and those who they aim that marketing at and saves the brands money. That's why the car manufacturers install it.

On the cars I've driven with it, if you lift off slightly on the pedal or go into neutral the engine starts up again and won't go off until I move again.

Which I thought was odd because in a very slow moving queue I don't want to sit with my foot on the brake, even in an auto. Maybe that more to do with driving an auto, being used to a manual.

Ingnoring the cost. I wonder about polution does it make much of a difference.

Well if the difference in cost is miniscule, IE the difference in fuel used over time, then the environmental positive is going to equally miniscule. That's on an individual level of course, extended out to most of the cars on the road it'll make some difference alright, but again it's going to be pretty small. If more people drove smaller lighter cars that used less fuel(and materials) in the first place and held onto them for longer that would make a bigger difference. My opinion, such as it is, is that it's a marketing sop to the public and much more a way for manufacturers to look like they're doing something "green" and reduce their costs against environmental legislation.

stop start is 10 - 12% more efficent, meaning 10 - 12 % less fuel used.

10-12% more efficient yet at the end they reckoned it would save the motorist about a hundred quid a year, so going by the opening statement that it costs about seventy quid to fill up the average car in the UK, not much more than a tank of fuel. Per year.

The other side of the argument is in a video that was suggested on your link

https://www.youtube.com/watch?v=k159M8QhCIE

And that research paper I linked above shows the savings very much depend on driving conditions, length of stop, number of stop/start events over time, with some conditions actually using more fuel with the systm.

I'd fall somewhere in the middle regarding the positives and negatives, but like I said in the previous post; if the difference in cost is miniscule, IE the difference in fuel used over time, then the environmental positive is going to equally miniscule. That's on an individual level of course, extended out to most of the cars on the road it'll make some difference alright, but again it's going to be pretty small. I'd stand by that. It makes a small difference and is much more about manufacturers introducing a cheap fix to get better lab results which allows them to sell more cars to the public under the "more green" banner.

yeah i hate stop/start... i press the button almost without thinking when i start the car to disable it.. i just don't like the hesitation sometimes of the car to stop or start especially in rolling traffic etc.. i have an odb11 device that ive used for a few things so must try it to disable the start stop completely... current car is VW tiguan... was on Octavia as well... same deal... another dumb implementation on the tiguan - Carnet message pops up after you are driving about 5 minutes and the message stays on the screen until you press ok...

Easily done with obd11 you just need to change the battery voltage in some setting I can't remember where exactly but there are plenty of walk through's online to show you.

I can't stand that arrogant fcuker, most of that Aussie stuff he yabbers on about are ancient European cast offs, that guy and Australia are stuck in the 90's

Flinty997

Pulling up to turn off a main road yesterday, the oncoming driver slowed and Signalled for me to cross ahead of them. As they did, I was rolling to a stop, so it cut out with the stop start. So as I went to cross there was a delay. I bet the oncoming driver thought I was idiot with terrible reaction times.

It should be configurable. Lengthen the time before it cuts in etc. Still you have the button to turn it off. So it's not that big a deal.

But if you are doing a lot of urban driving then a phev or EV is the solution ultimately. I assume they have instant response from the battery.

CoBo55

I think the summary is that stop/start is almost universally hated in auto's particularly VW derived DSG cars, I have to agree it was very annoying when I had a DSG car. In manual cars it's more bearable as you can decide when you want the engine to stop by observing what happening ahead.

You should never use the apps, use the coding it's the safest method as you'll only adjust what you want want to and if something goes wrong you can find your way back. I used an app to activate cornering fogs on my 172 Octavia, it didn't work and left me with permanent main beams illuminated I had to get a friend with vcds to sort it out, it was a nightmare.

As long as you do a backup before using the apps you’re unlikely to get in bother.
The main USP of OBDEleven is the apps.

I’ve done a few things with coding but a lot more with the apps and never had a problem. If I had I’d just undo it handy enough.
