I had a P205C code come up for Reductant Tank Temperature Sensor Circuit Low in my ’15 GL350. It appears there’s an issue with the sensor on the DEF tank. I had the emission recall performed on 4/5/21. I have to assume that this is part of the emissions system and would therefore be covered by the extended emissions warranty. Should I have any reason to believe otherwise before bringing it to the dealer?
