P2001/P2600 ETC error code

Got my car scanned with the MB diagnostic software and this is what the printout shows under ETC:

Code
P2001 Component N15/3 (ETC [EGS] control units) is defective
Status: Current and stored


Event
P2600 The voltage supply of circuit 87 has undervoltage
Status: Event Stored


car runs fine, no lights are on and everything seems to be working ok

any idea what this means?
wife picked up car from mechanic after regular maintenance work and I won't be able to speak to him until sometime mid week.

thank you in advance

Your battery voltage is dipping below 10V during startup. Poor connections or dead battery.

Thank you Witek. Changed the battery recently, like one month ago. Had to go with Advance Auto Parts one due to being stranded away from home. Should I go back to a Bosch or whatver MB sells right now?

Most likely those codes are from that event. Just erase them and check again after few days. ETC uses non volatile memory. If new battery is ~100Ah and ~600 CCA it's fine.

MB uses AGM now which is made by Johnson Controls.

before you consider buying from the dealer look into a yellow top battery. They are very good batteries (i would argue the outperform oem's) and will run you about the same as the dealer will charge you for theirs.
