battery light flickering
 

i have a 2003 bmw x5 4.4. I notice when starting and driving the battery light flickers, could this be a altenator problem? Can anybody hele me with problem. Thanks !

Search here on how to monitor voltage in OBC instructions. You need to calculate your unlock code for OBC, search that too. Look at your voltage while driving. If it jumps around, possibly your Alternator, but don't forget to check the battery too.
