Im glad you have fixed the problem. I think first i posted the video with this particular problem. It took me 2 months to figure out the problem. I knew it was not a big deal since i can start the car normally but needed to find out what was causing this problem. I didnt know the auxiliary small battery was defective. I wanted replace it since it wasn’t charging properly. Accidentally i did not put the small battery back and started the car. Stop start sign came on but charging sign went out. Then i realised computer is sending the sign due to the faulty small battery. I replace the battery and within day or two stop start sign went out completely. I decided to put it on my youtube channel so other volvo owner will get help.
Nice video thanks. Just keep in mind that after replacing the aux battery, it can take a day or two for the Start/Stop warning to go away, and for that system to start working again. (though the charging fault warning will go away immediately)
Just watched another video about the Start/Stop battery. It seems that baterry is used when your your engine starts at traffic lights to prevent voltage drop. As opposed to what I thought: that this extra battery is used to start the engine when Start/Stop option is on.
Nice video...thank you. I had the same problem...but after watching your video problem solved. Only difference is I really hate the start/stop function so I just disconnected the small battery altogether and the 12v battery icon on the dash board is gone.
Great!!! When small battery get faulty the system automatically get to the conclusion the charging system is down. I discovered this accidentally, when I took the small battery out for replacement the charging fault went away. I figured it out the computer is giving fault signal. Now if the charging fault comes back again automatically you know the battery in the rear is bad. Good luck!!! I’m glad that your problem is solved. I suggest replace the battery. It will give you more millage on gas.
I agree with the better milage, however the wear and tear on the starter motor needs to be considered when the engine shuts down and restarts all the time. Again thank you for the video and solving my problem. I'm sure it will help more people in the future since there are very few explanations on the internet to issues regarding these xc90's.
@@JIS001 yes..but you have to do it everytime you get in the car. It will reset to the the default which is to keep the start/stop function "on" and working. Scrolling through the menu everytime you get into the car to turn it off becomes tiresome. Wish they had a hard button to disable like in some other vehicles.
Could you do a video on the driver's door, my door won't close all the. I have to tighten the bolts on the holster because they come loose and then make sure the door latch is in the C position. I used Wd-40 which helps for a bit and then it happens again. I have a xc 90 2016.
I just started getting this error as well. I checked both batteries, and they're both at full charge. What do you think the problem might be in this case?
@@BengalTiger Thank you for your reply, I'll try that. Do you think perhaps I might need a new alternator, or would the battery not be fully charged if alternator is bad?
@@BengalTiger OK thanks. I will take it to the the Volvo dealership. I was hoping to self diagnose and avoid a dealer visit, since my car is no longer under warranty, and a trip to the dealer tends to be on the very expensive side..
@@BengalTiger since you seem knowledgeable, I'd like your opinion whether you think it's safe to drive the car 80-100 miles with this warning coming up? As long as both batteries are fully charged I personally don't see any issue with driveability.

Hi you could use any auxiliary 12volt agm battery from 10 ah to 14 ah with start EN 170-220A. Standart size moto: height 130mm width 90mm length 150mm. I use Exide EK131 agm - its 30% more power but height +15 mm. So i replace braket to install it
@@andrewcherry3330 Dear Andrew! Very interesting. What exact battery did you go for? How did you make it fit into the case? Can you send a photo or a small video to show? - Thanks 😉👍
When you take the auxiliary battery out, did the start/stop service required display disappear? Is it ok to not to put it back or it just needs to be there for other functions?
@@topherpab6998 Yes. I simply covered the connections and put them back in the box and secured the box fasteners. Light/warning has not been seen since. it's been at least a month or more and driven daily.
If your car starts ok, yes you can drive. I drove about two month with the charging fault sign!! But it’s an easy fix. Fix it so you have peace of mind

First you have to see if your battery ok. If the battery ok than you might have other problems. I’m thinking you might have faulty alternator, which is failing to charge those batteries.
I have my same problem. 12v battery charging fault. I check alternator is over charging at 15.5 voltage. I changed the alternator is go away charging at 14.75V. Than I had started and stop message on, I check battery voltage is only 6 voltage. I have to change the new battery. The message still on. I wait for couple day to see it go away or not.
Thanks for the video! I received this warning light this morning and already fixed it with your help.

Any idea if you can turn off Start/Stop completely?
@@pano3232 you can, in the My Car settings 8n Volvo, I think it's the Eco mode off that disables it completely.
Just watched another video about the Start/Stop battery.

excellent! and i hate those bolts that want to "run away and hide"- so aggravating
Those bolt can run but can’t hide!!! Lol yes it’s true.
Great video money saver 👏 thanks a lot
Any time!
Very helpful. Thank you sir...
You welcome!! I’m glad it’s helping other Volvo owner.
I had exactly the same problem.
But I thought 11.8 v is low and y also cashed the big battery. Is it not low?
Life saver!!!
you saved me.

I might replace the whole door. I just got in to big accident
I just started getting this error as well. I checked both batteries, and they're both at full charge. What do you think the problem might be in this case?
Take the small battery out and see if the charging fault sign goes out.
@@BengalTiger Thank you for your reply, I'll try that. Do you think perhaps I might need a new alternator, or would the battery not be fully charged if alternator is bad?
Main culprit is the small battery but could be your main battery too. the alternator could be an issue also. You have diagnose all of these.

Hi! I can’t find a place online or anywhere to buy this battery (BTX12). Do you have any Link where I could get one?

@@topherpab6998 Yes. I simply covered the connections and put them back in the box and secured the box fasteners. Light/warning has not been seen since. it's been at least a month or more and driven daily.
can you still drive you car and be okay with this error message??
If your car starts ok, yes you can drive. I drove about two month with the charging fault sign!! But it’s an easy fix. Fix it so you have peace of mind
thank you so much!!
Hi, I got the same alarm. And I check that little battery, it's only 3v now..should I replace both batteries at the same time?
Change the small one only. If your car starts fine then you don’t need to change the big battery!!!

First you have to see if your battery ok. If the battery ok than you might have other problems. I’m thinking you might have faulty alternator, which is failing to charge those batteries.
Put back the old battery control unit and see what happens. Am thinking the new one might need software to work.
Allow few days and drive the car in highway so the charge could be set faster, I’m sure all the signs will go out.
Anyone ever deal with it still showing the 12V battery charging indicator after you changed to a new battery?
Battery charging fault should go out right away. Stop start function sign stays on couple of days. Unless you have a faulty battery.
I have my same problem. 12v battery charging fault. I check alternator is over charging at 15.5 voltage. I changed the alternator is go away charging at 14.75V.
