Hi I’m new my name is kyle I have a 2015 mercedes brabus g63 that’s setting a p13c523 code. For what I could google there is not a lot of info on this code. What I have done so far is check for misfire found none, check spark plugs and replaced because The spark plugs had 108,000 miles on them and not have been replaced yet. Check coils that look OK check battery voltage and alternator voltage. Both are OK also. After replacing spark plugs, drove it and the code came back, but the code is not setting a check engine light yet just keeps coming back in the ecm. Any info and help would be awesome.
So I was able to replace spark plug and clear codes test drive and have not had the code come back yet. Now I have a check engine light for p012800 “the coolant temperature is below the coolant thermostat specified temperature” any help on this could would be great I have no coolant leaks and both ecm temp sensors seem to be okay
