Check Engine Light On problems of the 2016 Ford F-350

Started my 2016 f350 super duty 6. 7 diesel on a freezing morning and drove to work. At lunch I started the vehicle and about 3 miles into my drive a slow speed the check engine light came on. I went to a local auto zone for engine code diagnostics and the reader showed code p20ba. This code indicates there is an issue with the emissions def scr fluid heater - emissions related. I have not had the opportunity to take my vehicle to a Ford dealer as they are completely booked for service calls. I searched the internet and found a recall for this issue in prior year models of the same vehicle years 2011-2015. There is no indication of a current recall for the 2016 year model so will likely have to pay upwards of $1200 (search information indication) to get this emission repair completed on a vehicle with ~60k miles. Since the body style and engine changes for this Ford super duty model did not change until 2017 I'm hoping this recall will be extended to the 2016 year models as this seems to be an ongoing issue with other owners. The recall I am referring to is Ford customer satisfaction program 18m01. The attached picture milage is not represtetative of this vehicle, the vehicle has about 60k miles on it. Thanks for your consideration.
