Other things to check are the brake pedal position and whether the seatbelt is fastened. Both can prevent the system from engaging.
That’s a good point! I once had this issue and didn’t realize my seatbelt wasn’t clicked. It was annoying!
Try resetting the system by disconnecting the battery for a few minutes. Sometimes, a hard reset can solve minor glitches.
This could be worth a shot! Just ensure you have any codes saved before doing this.
And remember to check if any aftermarket accessories are causing power drains. It might not be the car’s fault!
You could be onto something! I had a similar issue with my stereo system draining my battery.
Isn’t it frustrating when cars have these quirky issues? Make sure to check the fuse related to the start-stop system as well. It can be a simple fix.

Totally! I’d also suggest checking the owner’s manual. It might give you specific troubleshooting steps for your model.
You could call BMW support, but prepare for a long wait. Alternatively, online forums can be your best friend for troubleshooting!
Haha, isn’t that the truth? I’ve spent hours on the line before! Forums like this saved me once.

I just hope people aren’t too reliant on forums. Sometimes it’s good to have a professional check things despite our best DIY intentions.
I had a similar issue with my BMW before. The start-stop system wouldn’t kick in at all. I found that it was a faulty battery, and replacing it cost me around $200. After that, everything worked perfectly again.
Interesting! Mine turned out to be a sensor issue. I replaced a brake pedal sensor, which ended up costing about $150. After that, the system worked like new!

Wendy, did you notice any specific warning lights? My friend had start-stop issues and it turned out to be a malfunctioning alternator. That repair was around $600, but it solved the issue completely!
I haven’t had any luck with mine either. The dealer wanted over $500 just to run diagnostics. Is there an easier way to troubleshoot this on our own?
You could try checking for software updates first, Melissa. A lot of times, they can fix these issues without costing a fortune!
I had to replace my battery last year, and it still doesn’t work right! What battery did you guys go with? I might need to try a different brand.
I ended up using an OEM battery, and it worked wonders for my start-stop. I think it’s really important to stick with OEM parts for BMW; they just fit better and last longer.
That makes total sense! I guess I would be looking into changing out more than just the battery now. Such a headache!
For me, it was the ECU needing a software reset. Cost only $100 at an independent shop. Sometimes it’s simple stuff that makes a huge difference!
