This is the second heater in less than six months. I went the cheap route the first time only to find that once my DEF fluid level was too low the heater failed. I replaced it with this Dorman and I am very satisfied with the performance and more confident that I will likely never have to replace again so long as I have this car.

Had to drop tank and diagnose new issue after installing. Found that the suction tube wasnt drilled thru so pump couldn’t pick up def in tank.
