2015 GL350 - First CEL

13286 mile and threw up a CEL day before yesterday.

Initial diagnostics show something with a sensor on the AdBlue system. It has been at or below 0 for the past month where I live so maybe that had something to do with it. I was hoping to get to at least 20k before catching a CEL. Oh well, as long as it is under warranty, I don't really care.

Ha! My mother in-law doesn't know the difference between the oil dipstick and the blinker fluid fill port.

Of course it went to the dealer...

Please set a appointment with your dealer under warranty - it's not necessarily due to the "cold" - but the "heater sensor" circuit - and/or other sensors ReGen system will require dealer service to get corrected.

You have a low mileage GL350 - and GL350's are becoming rarer bird's - I'm sure it will all work out.

Keep the beat !
