*Need help* i Drive shows message "Increased battery discharge"

[hanhng]

Hi all, my E90 325i's factory battery was replaced by an aftermarket one as the car couldn't be start due to battery failure, but after that my car's i drive shows the above mentioned message and it comes and goes randomly, so I was thinking if any of you have encountered the similar situation like mine.

Regards.

Is the aftermarket one the correct rating battery? BMW requires higher AH.

Your model needs a minimum of 70 AH to 90 AH. Which means with our local battery you can use DIN 66 but it is NOT enough. you need at least DIN 88

Agree with Slyder.
Best to install original battery.

Do it quick. Otherwise it will damage the electronic circuitry and some equipment may fail..for instance the radio/cd player.

Thanks for the replies! The problem is created by the replacement of a DIN 100 battery. The mechanic had changed the setting and it's now solved
