I am having some electronic trouble with my 2009 35i...

There is a Yellow P warning sign come and goes. (Randomly, sometime when I start the car and sometime while I was driving on highway). I did lots of researches and most of them indicate it's a battery issue because of lots of short trips. And my clock always need to be adjusted after 1 week. (5 min late after one week)
However, I replaced the battery but the issue still there...
The error code by using BavarianTech is
A559
Clamp 30g_f cutoff
Error will not cause a warning light
Error is not currently present
Test conditions have been completed

Any guess?? could it be my angel eyes shorted and draining my battery?
Fuse? can I reset it?
 
Did you check the voltage from the positive on the battery to the body of the car with your meter?
 
just guessing but a corroded or loose ground at the battery or where ever the ground hooks to the cars battery will cause all kinds of weird things.
 
Checked voltage is normal, removed aftermarket angel eyes, used battery charger to charge overnight, unplugged battery to reset but after 10 min the warning light came on again. :headbang:
 
I found this on E90post forum

A559
Clamp 30g_f cutoff
Error will not cause a warning light
Error is not currently present
Test conditions have been completed
EXPLANATION: Pulled fuse out behind glovebox during tune install.
FIX: Make sure fuse is inserted. Clear and rescan.

Not sure if this will help but check all your fuses.

PS Also this was from another BMW model, and I'm not sure where the fuse box is on your 35i
