Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
What usually happens is low voltage codes will set in several computers in your vehicle when the battery becomes weak or dead.In most cases driving the vehicle for an hour or more and turning it off to reset for about 20 minutes then driving again will reset this message but in some cases what has to be done that I have seen and had to do is to clear out the low voltage fault codes with a scan tool fully compatible with your model that will plug in and communicate with all computers.In some cases the fault will not reset itself and the codes need cleared out with this scan tool or a dealers sds machine.
If any codes come right back when this is done then that code needs diagnosed to locate and repair the fault.You might also try to scroll through the menu on the instrument cluster to see if it turns off the message then on a restart as sometimes all that is needed is to scroll through the menu.
But if it does not reset then you will need the codes read out and cleared to resolve this here.Or further driving until all computers see no low voltage exists anymore.
