Auxillary Battery Malfunction

Question by 300Benz posted 6 months 2 weeks ago in C-Class

2015 C300. I was away for 15 days and did not use the car. Upon first use, Auxiliary Battery Malfunction came on red, after driving a few minutes, continued to flash every couple minutes in Gray. This pattern continued for a few uses (short trips), and has now stopped, after I drove a bit of a distance.

Should I be worried?
