    I recently reconfigured my MFD to display voltage in place of boost pressure. Until then, I had no idea what voltage my battery was putting out at rest. I’ve noticed that the reading will start out at about 12.3-12.4V, but then continually drop over several seconds until it settles at about...

    Appreciate any help! Didn't drive the car for a while - it's been cold and rainy and parked outdoors (I know, I know... didn't have a choice). Battery was totally drained. I used the emergency key, connected jumper cables to the fuse box, and successfully popped the frunk and turned on the...

    Hello, is this battery voltage at cold start consider low and need to be replaced? Did not drive the car almost 24 hours. The battery should be almost 6 years now and not yet replaced since I bought the car but I have been daily driving it almost every week since I bought the car 5 years ago. TQ
