CEL P203D Reductant Level sensor current high
For my 2010 GL350 60k miles. Has anyone gotten this error? it was intermittance especially if I park my truck overnite it will go away when I start it will come back in about 30 mins later. I checked the adblue level was really low so poured in 2.5 gallons, still have room for more. Hope this was the issue... will find out soon.
