"Charging Failure"
Hi Peoples,
I have a 2011 V60 D3 5 cylinder. Recently i have the "charging failure - Service Urgent" alarm on the screen. I have checked the battery voltage at tickover and its only 12.6v, which suggests the alternator isnt doing anything. It looks pretty easy to change, my question is, are these alternators self contained, or are they controlled from the car itself? and could my problem actually be something else electrical. The reason i question it being the alternator is it happened within 5 miles of driving though some pretty large puddles (6" deep and 10m long") after last weeks flooding. Cheers |
High miles ? The alternator regulator should be controlled by the CEM.
Try disconnecting the neg at the battery, let it sit for 1h then measure the voltage at the battery posts. See if it's a healthy 12.5v or over. My reason is, sometimes the battery goes bad and the alternator cannot charge it. If you are replacing the alternator, measure right away the voltage to make sure the old battery is still charging correctly. Inspecting all power cables is also good idea. |
We had exactly this message, have you checked that BOTH of your auxiliary belts are still intact? One of ours was snapped so the alternator wasn’t being driven.

The start/stop hasn't been working as often as it used to and it always says "battery charging". Now i had assumed this was just normal, but now i have this current issue that may back up that either the alternator has been low on output for a while or that the battery isnt great. Or both i suppose. Its never failed to start. |
