I registered the battery but still get the Increased discharge warning. Unplugged the IBS last night after parked, get no warning but car still doesn't want to start without a jump. When I placed the jump pack on it, the voltage was at 9 amps. It's a new battery?!?! What would you guys suggest my next move to be. Plan to take it in to BMW Monday but any info before will help. Thank you in advance.

You have something discharging your battery if you are getting the increased discharge warning. You can try topping off your battery with a trickle charger, but I'll bet you keep getting the warning. If you have comfort access then my bet is that one of your door handles is faulty and preventing the car from sleeping. You can test this by coming near the vehicle with your key and see if any of the car unlocks or locks when you are near. |
That was the second thing I checked. Ever door handle works with no issue. As a last resort today, I took the car to AutoZone to check the battery. Their machine said it was a bad battery. It's weird because everything else works. Lights, CAS, seats, radio, etc... Just checked the battery and it still reads mid 9's. I'm still taking it to BMW to confirm but so far sounds like a battery.
