Help! 2005 E320 43K Miles Low Battery Accessories White Error

Hey Guys,

I need your help in an issue I can't seem to figure out even though I've replaced a ton of parts.

I am getting the Low Battery (In White NOT RED) accessories issue.

Before I came on here and posted believe me I've done my research and here is the list of parts I've replaced.

Rear Battery ( Replaced to Bosch Factory )
Front Aux Battery (OEM)
Alternator Voltage Meter
REAR SAM
ALL Fuses Inspected and Replaced If Bad.

I don't see it being the Alternator as the car has 43K Miles and Voltage is fine. The Light comes and goes sometimes when the car starts sometimes when I'm driving after 10-15 mins sometimes it goes away and then comes back.

After countless research Ive come down to it possibly being a few things left.
1. Aux Battery Relay
2. BSM in the Trunk by Battery
3. Seats Sensor

Would appreciate help! Thanks!

Some pics of the car!

check ur voltage when running the car stationary it must be between 13,5 and 14 slightly fluctuating is no problem.

Only then u can rule out the alternator.
