Hi everyone;

I'm having issues with my BMW 545i 2005 its showing up "increased emission" also, the battery red light showed up today and I bought a new battery cause the car didn't wanted to start this morning I changed it myself and car started normally, but now it keep showing up the same thing. I heard that I have to take the car to the BMW dealer to register the battery, I would like to know if the dealership can only register the battery or any person, car owner can?

Also can someone explain why is showing up "increased emission'' what can I do to fix that cause its also showing up "check engine red light "
