2016 - 2500 Silverado with 2400 miles on it - 57 hours on the motor...While trailering a 29' - aluminum 4 place snowmobile trailer from Pittsburg NH to Saguenay Quebec in 28F weather the cluster reads DEF level is @ 30%. Not a big deal, pull over and top off the fluid. 150 miles later & 2 -3 on off engine cycles the DEF gauge still does not register full but had dropped to 28%.
Fortunately Arnold Chevrolet is located next to the hotel in Saguenay. After dropping the trailer I drop in unannounced hoping they tell me to turn the key and press the pedal a # of times and it will reset. NOT ! The service writer informs me it doesn't work that way. A technician was required to reset the gauge by means of computer. I am told that was the only way. A 1/2 hour labor for a total $ 65CAD + - and my gauge has been reset and I am out the door. The service manager told me to claim the $ with my dealer when I return to the states. I'm happy as ARNOLD Chevrolet dealt with my issue immediately with no messing around as it was near closing time when I stopped in. I only hope the DEF gauge continues to read "OK" on the way home as we have a lot of hills to pull in not so so nice weather conditions during the 310 mile one way trip trip and can't afford this beast to go into limp mode because of a faulty DEF reading.
Wish me well on the return trip....
