330d E90 Battery Warning - Help Diagnose
When I switch the car on I get the battery warning light now. I would like to know how best to diagnose this? So far I have accessed the hidden menu and noted that the battery voltage while the car is switched on is 11.2V and while the car is running/driving - the voltage sits around 14.3V.
What steps can I carry out next to determine if it's a fault battery, alternator or alternator voltage regulator? |
