STOP/START is a feature on modern cars to reduce emissions by reducing the idle time on your engine when stationary. This works in theory but in reality, there are often issues causing this system to not work as intended.
there are certain criteria that needs to be met inorder for the system to work properly.
this differs from manufacturer to manufacturer so we always recommend checking out the owners manual for a comprehensive list, but we will go through the main reasons that people run into issues here.
1. AC, Your Air conditioning being active is considered too high a draw on the battery when the engine isnt running. the car recognises this and to prevent not having enough power to restart, it de activates the function all together.
2.Engine coolant temp. the biggest reason for wear on your engine is during a cold start up. this is because the oil hasn't been fed through the engine yet so the car intentionally waits until the coolant temperature is above a certain limit which ensures a good operating temp for the engine and that sufficient oil has gone through the internals of the engine. once this criteria is met, stop starts when warm have minimal wear effect.
3. Repeated stop starts. once a succesful stop and start has been carried out by the system, there is a minimum distance and/or speed that has to be met before another stop start can occur. this is to again ensure the engine has enough time to recirculate oil through the engine and prevent premature wear.
4.DPF clean. the diesel particulate filter collects soot from the engine and occasionally runs through a self clean procedure. while this procedure is being carried out the engine must remain running. if it is interrupted then the process will need to be repeated the next time the car is started up. the system knows this and de activates the stop start system to make sure it doesn't interrupt the procedure. too many failed dpf cleans can cause a blockage in the dpf.
5. Battery State of charge. the battery must be over 80% charged. if this threshold isnt met, then the stop start wont work. This is because the system weighs the risk on if there is enough charge to restart the engine similar to the AC issue.
if however the engine stops but you are waiting for a prolonged period of time, the battery may fall bellow the 80%. this would mean the auto start up kicks in before intended as a way to counter act the issue. this auto start up would kick in if any of the listed criteria isnt met.
Stop start complaints will be very common the more people start using their cars again after lockdown. we hope this video has given you something to think about if you run into these issues.
hope this helped, have a great day and STAY SAFE people! - Auta a dopravní prostředky
This is a great video. It’s a covert way of telling drivers how to permanently disable that crap.
Very clear and precise information. I did not know any of this could affect the car stop/start operation. Thank you for explaining it to us more clearly 👍👍👍
Glad this helped.
Excellent Information. I had iss8and I checked my main and auxiliary batteries.
Aux was fine but main was done.
Soon as I renewed stop/ start eco worked again.
My car is a 6 year old Mercedes E250 cdi.
Still a great motor and efficient too.
Thanks, The presenter appears to really know his subject . Video was very well presented , very informative & appeared to cover the issue well.
Thanks this has solved my issue with start stop not working. I didn't have time to put my car in the garage for diagnostic so this video has been a blessing thanks again 👍
Really glad this video was helpful to you!
Hi,thanks for the heads up,my Kia Sportage 1.7,has never worked since I bought it, probably air con on all the time!
Excellent and highly informative video. The picture is crisp clear and the narration is great and easy to follow
Very helpful advice, well done.
Good information, this obviously applies to all makes of car with s/s
You are an expert on what you do.
Thanks for the battery info 👍
Thank you! Very informative, i know nothing about cars, and this was really clear, thanks!
I can't believe people would actually complain if that system disabled itself permanently
For me it saves me around 50 to 70 miles in fuel economy so yea the complaint isn't just about annoyance!
Thanks for informative video! 👍 Our car stalled halfway, we didn't know what to do. So I watched this, turned all the heat, seat heating off, and it started, so we made it home.🙂
Glad it helped!
Great video. Stop start no point in having it more trouble than it worth
Very good comment, very professional, good luck with your site
I'd deduced a lot of this a week into owning my first car with Stop-Start but also noticed that it tends to manifest as the car deciding it will or won't work at the start of a journey and then nothing I do on that journey will change it! I do noticed the failure tends to be on the outward journey after sitting for a a day or so so I guess it's almost always down to the battery charge (I was doing things like turning off the AC and even the heat/fan down).
I've decided to stop worrying about it now :)
Thanks you’ve helped me loads
Got a week old new car and was wondering why the stop/start wasn’t working… checked the battery and it’s at medium/low on the battery tester so that’s why the stop/start isn’t working.
Thanks for this info. Saved me having to hit the garage.
Glad this helped 😊
@@MTMMotorServices you was 100% right… now the battery has charged enough my stop/start is working again… Now I want it to stop working lol. I can turn it off but only for 4 minutes at a time. 🙄
Can you do a video on how to permanently override them?
Thank you very much, great video.
This was so helpful. My fiat 500 randomly shut off the stop/start and it worried me! especially since i had just serviced and MOT'd my car that month. Turns out i just needed some coolant and the aircon had shut it off as said. Thanks mate
Glad this helped!
Although if your coolant has dropped since having a service that may need looking into.
Coolant level should have been checked and topped up during service
Great Information...Dashcams also Inhibit the I-stop function.
Excellent video, told me all I need to know in 3 mins, thanks
Glad this helped
very well explained, clear and concise.
Thank you finally solved my issue just feels weird when that stops working in your car my car kept shaking a little when I stopped at a light then cut off but it cranked up
Just got a 2 yr old 3008. There's supposed to be a start-stop system. Gonna check the aircon as I think that's the most likely scenario. Many thanks
Great advise on this subject...CHeers
Thanks for the tips! Is there anything related to disconnecting the battery for a short time? I had to move the battery to replace a headlight bulb and it stopped working after that.
Thank you so much, helped a lot.
Thank you for the concise and helpful information!
Great video and good explanation.
Very informative and thanks for sharing your experience, My Renault capture doesn’t start at all it’s euro 6 1.5 K9k682 , I have manage to start with grounding pin 3 on UCH TEMPORARILY, any thoughts much appreciated, I don’t mind paying for tech support as I’m limited to French manufacturers .
Helpful information thanks
Cheers for posting, very helpful info there on an issue I'm having, have subscribed 👍
Very informative thank you
Really clear, informative, useful and helpful video. Thanks for sharing. The owner’s manual for my Kia lacks any sort of troubleshooting information. The video helped immensely.
This has put my mind at rest and i now know why the stop/start won't work. Many Thanks
Glad this helped :)
Great, thank you
Very useful as one of the criteria fitted our situation
Glad this video helped :)
@@MTMMotorServices Sir,
My Mazda CX-5 2017, start stop doesn’t work. Sometime it work but after travelling for half an hour if I stop the car, and just for the check up if I press the break the green light is flashing on the s/s button. I can’t start the car. I recently change the car battery and it was set up properly. Could you please do me a favour by figuring the real issue on my car! That would be great help and will be appreciated. Heaps of thanks.
Thank you for teaching us sir
I couldn't start my brand new Toyota 2020 , 2 × week or 2 after stop start not available ,they 2× changed battery and did software update.
Buttery drainage ,now I have same problem. Thank you for explanation.
I have a BMW 530 d 2017 with start stop which works, my wife has a 320 d 2018 and it will not work. thanks for the info on the battery I think it needs a good charge.
Very useful thanks. Can someone tell me what health percentage does the battery need to reduce to before a new car battery is recommended? Because under %80 to me sounds like battery is still in relatively good health ?
Charged my battery for a few hours,even though I’ve been driving it, all ok now thanks for your helpful information
i would check the alternator, this should put charge back into the battery
Well done!
Yes!! Thanks buddy!
I have a Fiat Qubo 2011 with stop start function and ive been told it can have either stop start battery or normal battery.Chances are i wont use this function as with city driving i dont want egr valve and DPF getting clogged up with frequent stop starts.The advantage of the gel battery is that its better quality and holds more charge.
Took mine to the garage for starter motor issues. Do you think the mechanics will check the battery first?
Good video thank you
My 2016 MB GLC s/s just worked for the first time in two years….I was on a 60ml as I often do, trip aircon was on and it was 30* 🤷♂️😅
Great video and information, I haven’t been driving my car BMW 218i Grand Tourer during lockdown/cold season probably once a week for few miles and now my start/stop won’t work at all, I was wondering how do I get my battery charge up above 80% ? Is it just by driving longer or I need to take it to the dealer ?
Thanks and subscribed.
You can take it for aong drive in order to charge up the battery. But the best way I have found is to put it on trickle charge with an at home charger and leave it overnight.
Great video with valuable information. Thank you
Thanks you sir
Having rear demister on can also stop it working on some makes.
great video! my start stop (eco mode on peugeot) is notbworking and the peugeot service told me something about the multiplier of the battery needs to change and will cost me about 500euro , and i am thinking is there any chance if i dont fix it will cause me mite problems?
Big thanks
Can you charge the battery on a Volvo XC60 with the terminals still connected
Excellent description of the fault. Thank you.
Use a cheap smart charger and charge the batteries over night. My Volvo gives a low battery message and start stop doesn’t work( it tells me in the settings that it’s unavailable because the battery is charging) doesn’t get driven long enough distant to charge it so The battery charger will do it and charge the support battery as well.
Really useful video, thanks so much. My new car's reversing sensors aren't working at all. A future video on this topic would be so helpful. My car's a 2016 Citroen DS3 1 6 Diesel. Thanks again. 👍
are your reverse lights working? most aftermarket reverse sensors are linked to the live for the reverse lights, so this is something to check.
otherwise if they came as factory standard then they could have their own separate live. if you have your owners manual, you could locate the fuse and check that hasn't blown. there are a few other things that can be checked too, so ill keep this topic under consideration for a future video. Thanks for bringing it up.
I have a 2011 Nissan Qashqai, The (A) symbol shows as its working, but even after long drives, my car never actually stops at any point ever. Could this be a battery issue? would i need to replace it?
On your other video what was the reason for the starting problem on the mokka? I have the same problem but cant find the fault
Hi my Kia Sportage g T line mild hybrid 1.6 stop start isn’t working ? I travel everyday to work about 27 miles .Since having the car it hasn’t worked I bought it from Kia it’s going to the Kia garage they are going to test the battery the light comes on but it’s orange not green ? Look forward to your input .
I watched you video which was good advice. I've got a BMW 320 year 2012 and I've changed the original battery to a new one but unfortunately the stop start still doesn't work. Not sure what to do now.
With certain BMW's you have to tell the car via diagnostic machine that the battery has been replaced.
Thank you it's been really helpful
Hi there I own a seat Leon 2016 tdi sometime when I drive the car after warming a bit and I turn the fan when is raining then the start :stop system is not functional please if you find time can you tell me what I do wrong
If the battery is at 80 percent how many miles in day light will you have to drive so it goes back to full..on motor way...
is there any way i can tirn off the stop start all together mate?
It would be a blessing if the Stop/Start system stopped working.
most cars you can turn off the stop start
Ok, I have a 2017 ford escape titanium 1.5L FWD. I just did a transmission swap.( old one died, had hard shifting problems and then after driving for over an hour it just wouldn’t go into gear and got stuck in a high gear and just burnt up trying to get it to a parking lot) the transmission swap went really well but now I have this one issue. The auto start stop will do a hard shift when cutting back on, this sometimes doesn’t happen if the auto start was active longer than 30secs to a minute, ( it’ll work as normal) but if it was activated at like a short stop ( ie a stop sign) it’ll do hard hard shift then drive normally… the adaptive values and KAM was reset to my knowledge with the new transmission. Any thoughts on what the issue is?
Im using Q5 2017, started DPF fault, then start stop fault, then come up drive system fault, i hope these all related DPF problem, could you answer me please
On short trips of 5-7km the battery does not charge more than 70%, that's if I still light up the position and "force the charge"
After 50% the battery no longer charges with 14.8 decreases to 12.8 and with the positions on it charges by 13. 8.
Disabling the start stop doesn't help much.
Do you have any idea of a "trick" to trick load management into sitting in 14.8V?
Excellent video. I'm sat in my daily driver A6 C7 (after having not started it for two weeks) with a "start-stop system: system fault! Function unavailable" message on the Colour DIS. I'm going to run it for 20m for the battery to recharge and check back tomorrow. I've not received this error when I've been regular with starting engine up at least every week. Any advice?
I'd recommend leaving it trickle charge overnight. That's the best way to rule out the battery . Even though you drive for 20 minutes you won't be 100% sure the charge has reached the threshold in that time. An overnight charge is a good way to not only get a good surface charge but to re engage those battery cells which have been dormant the last two weeks.
If you check out the video for 5 tips for lockdown. Number 1 is to keep the battery charged. To do this I use a smart charger which charges the battery with a low amount of charge over a longer period of time.
Heya my 2014 e class stop start stopped working about 6 months ago ( no warning lights) any ideas?
Thanks in advance
Hi my friend has a 71 plate nissan micra auto . And the start stop worked a few times when she got it and apparently has never activated since and it's been 7 months now?
Is it OK to disable this feature on a mini cooper, and will it affect the battery duration?
Excellent explanation. I do after stopping and when stop/start isn't working most often see the circled "A" stop/start icon with a diagonal line through it, with the text "For Climate Control" next to it at the bottom center of my display (2022 Rav4). It displays for a couple of seconds after the car's stopped, then disappears. The car's less than two weeks old, and the dealer's service dept. has me waiting 10 days to get in! Any thoughts on that error message? It makes no sense.
If the car is new, it likely hasn't had a good enough run to fully charge the battery,
They should do tests to conform this when they have the vehicle in. But 9times out of 10 when I was in the dealer, this was our main issue.
Hia mate my honda civic 2012 once started on the 1st start stop 1 min away from my house kicks in but on that 1st start stop once the car restarts it has a loss of power or accelaration causing almost a stall, is this normal? After this the car will run perfectly without any issues or problems
I have a Audi A5 from 2013.. when I bought the car , even with a/c always on . The start and stop always worked even when I’m driving on sport mode .. for some reason . Start and stop only works with a/c off… any help? I would like to get back to Normal.
I got a new 2022 q3 I have only driven it on weekends. Is that potentially draining my battery, sitting in the garage?¿
Second hand B class it never worked and no warning messages, wasn’t that bothered and drove it for two years, main battery failed, fitted a new one and it started working.
I replaced the original 8 year old battery, sorted 👍. Merc 2014
I have a 2014 Ford C-max on gasoline. I replaced the original battery 6 months ago with a Varta one and the start / stop system no longer works. Is it possible that the mechanic put a battery in the wrong start / stop system?
I have a problem with a 2013 astra diesel. With the eco mode on it will randomly kill the engine then won't start. It cranks but it choke as iff it's not getting fuel or air. When it starts the clutch often wont disengage when in gear for about a minute. With eco mode turned off it doesn't happen.
I always wondered why my Start stop never went on. Apparently its the A/C and my auto temp is set too low
Mine actually said auto stop start not available Due to vehicle charging.The Wal-Mart automotive services suggested that I unplug all the USB ports Drive around a little bit and come to a complete stop and it should work And sure enough they will right. It worked again. Most of all, do not use accessory mode at all when parked.
I have driven two rebadged Opel diesel Insignias with this system. It stopped working in both cars at around 65000 miles. The second car has had a new battery and over 130,000 miles and it still doesn't work. Also when it worked it would not operate after about 3 or 4 cycles in traffic whether in town or on the motorway in a traffic jam. The particulate filters in both cars were in full operation. The second car also has Adblue fitted to reduce NOX emissions. Frankly the stop start system was just a gimmick.
Does anyone know if it can cause problems changing gear when it’s not working properly?
I'd be quite happy if the stop/start stopped working on my three year old Dacia. It'll save me having to remember to disable it every time I start the car. Cheers!
Sir i need your advice as soon as possible.My car ..opel corsa diesel 2016... doesn't have a button to activate or deactivate the start stop function...i recently changed my battery and suddenly my car stops and starts operating automatically when speed is zero..usually in corners and stop signs..Any ideas....
Thank you. I can stop worring now.
My problem is my stop start just doesnt do it. Ive had a look with a bi directional scanner and you can activate it via the scanner, but it was programmed after a new battery and now just doesnt do it. So... Battery not suitable? Or some programmed value out of range?
In my Clio start/stop is also disabled if circulation is set on the windscreen. (Defogging)
Can you help my 2019 Mercedes GLE 400 twinTurbo my stops that have not worked in the four months that I’ve owned vehicle batteries a good green light on to indicate that it’s working but it does not stop start the vehicle any ideas thank
I understand how it all works but does battery management look at volts or the amps in the battery. Because if the volts are there im seeing the systems are still trying to work. But the amps are not there causing another issue. What do u think.
It looks at amperage, but it also monitors how well the cells maintain a charge and it determines a "state of health" aswel as a "state of charge" this can take 24hrs to monitor. because of this, some people opt to charge the battery slowly with a "trickle charger" often leaving it charge overnight to bring the battery back to tolerance.
@@MTMMotorServices cheers for the reply. But do all manufacturers battery monitor systems look at amps. Only reason i ask this is vag stuff i believe looks at volts. If it looked at amps then stop start wouldn't have a issue. I.e. stop starting a lot in one month on short journeys kills the battery. Where as someone who live i countryside dont have issues as there able to charge the battery enough.
Would u advise people in heavy condensed cities to switch the system off if they are stop starting in a 5mile drive more than 50 times. As ive seen a person stop start more than 200 times in a drive cycle and 8 times the system failed where they had to manually start the car. This in my eyes is a human error not car system error. Education advised on stop start, etc. What do u think. Cheers.
Hello sir, l have a car model is Kia sorento diesel 2017 that car problem is auto stop system not working battery is new. why?
Ah !! ok That makes sense thanks for a great vid.. Personally, I hate it and always turned it off but now it wont turn on i'm. like. why.!!! lol
"Better For the Environment" really means slightly less destructive to the Environment..
My battery was bad so I changed the battery to a completely new one but it hasn’t reset on my car and the start/stop still says unavailable I have a jeep compass is there another reason for that
You might have to check if you have to tell the car it has had a new battery via diagnostic machine.
Otherwise, 24 hours after the replacement the sensors should detect the change in battery quality
First point is already a miss. most cars power their aircon by the movement of the engine (belt) and not through electricity. so the air con will not draw current it will just not work, and therefore s&s may not kick in.
