NCS Expert only way to code battery AH?

skiracer8148 · 03-21-2015, 01:33 PM

Recently replaced my battery with an aftermarket but the car is still acting funny and I don't have functions like comfort access and reduced blower motor speed. I reset battery registration with Bmw logger but I believe the car is still acting up because the new battery is 80AH vs oem 90AH?

ISTA P can also do it. It's a mandatory to code the new battery type.
