Actually any ordinary batteries can be used in this m3, if you don't care the i-stop.

we got good price for Q85 battery spec, around 400+ but that's the price for member m3sa only

Look for Auto Marques Express in FB

It needs to have something feeded into it by replacing certain scripts or changing its values. I looked at the coding before. Not sure what counts for not touching the firmware but doesn't really matter to me. I use the same thing you do except I did not pay for that app and got it for free in the forum. You don't have to have the script permanently in the USB, it is a one time thing. If you didn't have the USB with the script plugged in after the first time you did it, it will still work. If I am not wrong, if you keep it in, every time you start your car you are basically re-feeding the script again (I may be wrong). But glad it works fine for you!

You can just tell your service center about that (the kurk kruk etc). It's a known issue and they have solutions for it.

This bold statement said everytime driving we need to turn it off? so what is the purpose to have this function at the first place?this really a joke right. We save fuel today and that save portion will invest back to buy a battery.

Thanks for your reply but they don't have Bosch EFB. Managed to find out that this is sold by Dynabond Battery, Puchong.
