Greetings from SW Louisiana, looking to gain knowledge on various engine codes now that black betty is at 111,000 miles & out of warranty. Hoping to do what I can on my own & save myself the frustration of a dealership. currently I've got a P1338 Cylinder 1 Glow Plug Offset Exceeded Learning Limit & P1050 Reductant Level Sensor Invalid Range. I'll be searching the forum if anyone has links to save a bit of time it would be much appreciated.
