Hi guys

The other night I get a "Charging System Fault" and the battery symbol light up on the dash. -
I got home, 30 min drive, nothing seemed to shut down. IID showed low voltage on the top corner but no faults as such, just restricted performance which would not clear.

I am too busy to even deal with it right now, I was just happy to make it home. Since then it started fine as I needed to move it and also I didn't get a "low battery" warning. "Charging System Fault" did come up though. But it cranked and started fine.

I know the alternators go, but before that shall I check other stuff first, eg battery terminals?

Cheers. Cheers, Greg

I had exactly the same issue, and was told I needed a new alternator despite it being only 4 years old. I fiddled with the battery condition monitor connector at the battery, and 3 months on the fault has not returned. Nothing like a free fix! 2011MY 4.4TDV8 Autobiography Baltic Blue

Greg,
A picture I took several years ago when I replaced my battery.
I didn’t unplug the connector because there was sufficient slack in the cable to just move it out of the way.
Early cars like my 2011 have the cooling fan attached to the BCU, but later 2012 cars don’t have a fan.

Cheers
Mike.

Hi Greg, I’m pretty sure it was the connector with the blue wires on the negative terminal. It was also suggested that an alternator brush could be stuck. Maybe coincidence and the brush ‘unstuck’ itself at the same time I cleaned up the connector. When the error code came up, the charging voltage dropped from 14.3V to 13.7V. Hope this helps. 2011MY 4.4TDV8 Autobiography Baltic Blue
