So, starting last night, the door handle sensor stopped locking and unlocking, had to use the remote to unlock and lock, and engine started normally and instantly, but a dash warning says "Electrical system: Low battery, battery will charge when driven" or something like that briefly and everything back to normal, and door handle sensor would work if I stop engine and lock it right away, but if I wait like 5 mins or so, the sensor won't work, does this look like the battery is charging but dropping voltage rapidly?
It's a 1.5 yrs old Varta EFB battery, I never use Start/Stop. Scan came back with U141100 Battery terminal recognition open circuit, and battery is at 13.7x with engine running and 12.1x with engine off, does this sound like a bad battery or should I have the alternator looked at? Thanks!
