Why has my START STOP stopped working on my BMW? Faulty Start stop. F20

[@scottparker4568]

Fascinating! I was getting really worried as my '19 540i just doesn't to activate this feature as much as I thought it should. After seeing this I realize now there's much more to it than I thought! Thx Brother

Wow, this video is very helpful, thank you

[@mattsbeamer]

Thank you for your kind words :)

[@venatusHD]

Bro please keep doing the bmw DIY videos, im so thankful with you, you have helped me a lot! Greetings from mexico!

[@mattsbeamer]

venatusHD hey bro. Thanks for the kind comment :) I’m trying to think what I can do while my car is running perfect lol :) I was going to do stuff to my door mirrors, but I’m scared the glass with break :)

[@venatusHD]

@@mattsbeamer It´s there any chance you can help me to diagnose some error codes? I´ve tried different things but nothing seems to solve the issue, the engine light turns on again.

[@mattsbeamer]

venatusHD hey, what are your codes. Maybe I can give an opinion.

[@venatusHD]

@@mattsbeamer P0172 its a system to reach code, also P1180, I already change the top o2 sensor the one behind the turbo, also I change the spark plugs, change the oil, the Mass air flow sensor seems to be fine, really appreciate your help, merry christmas !

[@venatusHD]

system too rich*

[@marcsolloway3941]

I often stay in gear and hold clutch down to prevent the start stop from working unless it’s a really long traffic light, just more wear and tear on the car! No problems with it though once car has warmed up, 4 year old Audi A3

[@scrowin]

I loved having my 2016 228i until it would not start after going to the bank. Codes indicated the starter was bad, replaced the starter. After some remote diagnostics, the FEM module was determined bad. However because of the chip shortage BMW has had a back order list from April 2022 until now NOV 2022 with 1100 BMW sitting a dealers waiting for these FEM modules. The starter had over 11,000 starts and possible caused a voltage surge as the code indicated. What a crap design to have cars start and stop the engine so much. Minuet fuel saving compared to the swapped parts that end up in the landfill. Sad to see this car go away, it was a fun one.

[@sshinde2629]

Thanks, I was worried initially, but the weather was pretty cold last week. Also, when I checked the battery it was at 2 bars (on the trickle charger). Now need to drive it a bit later it gets warm enough and full battery to check if it works properly and look at the other mentions on the list. The other thing is that the battery doesn't charge unless the car goes above 50 mph. This is not possible in town.

[@mattsbeamer]

Thanks for sharing your experience, it will be interesting seeing if yours starts working soon :) good luck

[@sshinde2629]

@@mattsbeamer Yes, it works fine now. Battery reasonably charged and engine warm as well the weather around 10 C.

Thanks man 👍 I don't like either but if it is not working, i am asking myself that maybe the car have something and not working properly. 👍 Thanks and Mary Christmas 👍

[@justaroundthecorner2883]

The start/stop is little more than an expensive gimmick. All it does is wear out the starter motor and land you with a huge bill. Thank the Lord it can be deactivated. Thanks for the upload.

[@mattsbeamer]

I’m so glad that are people out there, who agree with me!! Have a lovely weekend

[@NdwambiMboniseni]

Hi my f30 328i if it stopped with stop and start on the stop sign it doesn't start again I have to wait until it cool down what could be the problem?

[@celvin-xb1bg7tw4m]

when my BMW 2 series engages the start stop system it flashes up transmission fault, do not turn off and shifts into N. I then have to put it back into D to move on. I switch stop start off manually normally but sometimes forget. Taken to garage and they haven't a clue as fault doesn't show up on the computer, battery is fine. any ideas?

[@terrymetcalfe9503]

I have a stop start fault, comes up with fault CCID 397, something to do with zero gear position adjustment or gearbox neutral calibration fault. Happened when I replaced the battery and yes I registered the new battery. Any idea how to recalibrated or reset. Car drives fine, just an annoying warning when starting it and switching off

[@KellyFrench-b3e]

Hi there inhave a e90 320d . My start stop button doesn't work all the time and nothing happens and then I get a foot panel on screen telling me to push pedal

[@bobbydoo5780]

Does this work for gmc Sierra also ? Stopped working and I can’t find a video for it

[@niallhorgan4014]

My BMW Start/Stop is saying that there is a fault but doesn’t tell me what it is on the system just says I should go to my nearest bmw garage. The car turns on fine not sure if it is a battery issue? Some morning it might take a couple more seconds to start then usual. Would you think it is a low battery amp?

[@Suhailmaster58]

It's a battery.

[@lloydvehicleconsulting]

Yes, even my Seat Toledo, which is not even three years old, sometimes decides that the stop start system does not want to work for the most arbitrary reasons. These include the fact it decides the cabin temperature is not warm enough (!), the battery is not charged enough (usually around 80%), it is too cold outside, there is a high drain on the battery from the rear heated window or lots of other random things. Definitely not just a BMW issue!

[@mattsbeamer]

Lloyd Vehicle Consulting thank you for your message:) do you like your start stop thou?

[@lloydvehicleconsulting]

@@mattsbeamer, yes, on the whole! It works better than the system in my previous car (the diesel Chevrolet Cruze). That was a pain as it would not even work if the Diesel Particulate Filter failed to re-generate or the oil had not been changed or there was a week in the month. etc....

[@mattsbeamer]

Hi, I have a bmw x1 and sometimes when the start-stop turns on while stopping on a red light and then I left the brake pedal it says that there is a problem and the car pass to parking. Then I just put it on drive and keep driving, what could it be ?

I just bought my bmw 118 m sport convertible 2011, but I don't know what model it is, I mean, is it F20 or F21? And also when I bought the car start/stop was working fine after few days suddenly it stop working. Can u help me with this 2 questions please mate? Thank u 🙏👍

[@mattsbeamer]

Hello Sash. Thanks for the questions. I believe your car is a E88. The F generation convertible is called the 2 series :). There are so many tiny little issues which can stop the start/stop working, such as low temp outside, the battery level. I made a video on start stop a year or so ago, it should be the similar on the E88. I’m not a big fan of start/stop so I manually turn mine off each time lol. But since I live in Moscow it turns itself off when it’s cold :)

I have just seen that you commented on the start stop video. Lol

Hi, I have f10, How about if I have the battery lower ... I mean the health of my battery is poor (low) .. is this affect also the system ? Thank you !

[@mattsbeamer]

Hey, if the battery health isn't in great shape it will effect many items on the car including the start stop. Is your battery in bad condition?

[@marius-bogdanbizon6957]

@@mattsbeamer , yes .. some times is show me when I switch off the engine "charge battery" That's happened only if is could outside and I will drive for a short distance ! I mean the message on the dashboard " charge battery "

[@mattsbeamer]

@@marius-bogdanbizon6957 ok, first of all charge it up with a charger. I'm guessing your car has a AGM battery, so you would need a special charger. I have a CTEK mxs5.0. If your battery doesn't last long after that then it's best to replace the battery. You can also see the voltage on the secret menu (I made a video on how to open up the secret menu). It will be interesting to see how it behaves. Keep me updated. Oh remember if you get a new battery it will need registering to the car.

[@marius-bogdanbizon6957]

@@mattsbeamer , one good question I have : how about if I m going to replace the battery with a brand new one, it will end up the same ? Or it will be ok for few years ! And now the second question , if I m charging this battery it will survive longer ? Or it will show me again the message on the dash board if few weeks or when is could outside ! Thanks very much for all your answers, means much for me .. !

[@mattsbeamer]

@@marius-bogdanbizon6957 the new battery should last for a long time. My battery is from 2012 and is still going strong. I had to recharge it the other month for the first time. If your electrics are good on your car the or should last a long time. I know your car has a lot of electrics compared to mine, so your battery will have a lot more work to do. Its always best to take your car on long drives and not to many short trips. The battery has some kind if memory which will stop it charging fully etc.

[@princemaisela7907]

My start stop system hasn't worked in over a year now...i don't know what's wrong and it's warm summer now

[@mattsbeamer]

Prince Maisela I’m sorry to hear of your issue. What mode do you drive in? Try it in eco mode to see if that will make it happen. It may be worth sticking a scanner onto it, to see if there are any codes.
