My S class has been fixed twice so far by the dealer shop for Auxiliary Battery issue, yet still coming back....


1st time they replace the Aux Battery;
2nd time they update the software on the corresponding ECU.


Any one is luck enough to get to the root cause (with assist of the dealers)? So that I can tell my dealer shop to fix it for good.


Really lovely car, love it, just this issue.....


Thanks a lot

Be patient keep going back and next talk to management!!

Yeah, I guess before anyone share the root cause of it, we can only do so...
