Check Engine Light
Well I dropped my 2010 GL 350 with 60k miles off to get my bumper resprayed and then CEL came on. Using the snap on tool it came up with 2 error messages, but was hard to understand what they were. One mentioned Ad Blue and the other one was saying Can Bus fault. Now the previous owner had replaced the Ad blue heater and Nox sensors, could it go bad again with these miles? I reset it and just waiting to see if it comes back on. I also added some more Ad Blue fluid, but just filled it up 5k miles ago. If the heater or Nox sensors are bad again how long does the dealer warranty the replacement parts since my truck is out of warranty already?
