X6 Voltage
Whilst driving today, I noticed my window go up just a tad slower than usual. I've had no warnings and have gone through the msg's on the OBC, nothing at all about battery.
My battery is an AGM, registered and fitted at a specialists - about a year old, so should be OK, no issues starting the car up. I was abit concerned about the window, so I plugged in a cigarette lighter battery gauge. That was showing 12.6V, I had been driving for an hour. I thought the voltage seemed a bit on the low side.
About 8 hours later , I started it up again and the voltage on the gauge said 14.4 utpo 15 for a second and then steady at 14.4 I drove around for about 10 minutes after which the voltage dropped to 13.6 and stayed there, for the next 5 minutes. Then I parked up.
Should I be concerned about this ? Can it be an indication of alternator / battery fault ?
