I had the CEL pop on while driving Friday, took it to the shop this morning. Already done and back in my hands. It had one code set for Oil Pressure Switch no signal which had unplugged itself, most likely not completely seated at the factory. And one pending code for EGT Sensor fault. I should add I'm a 21 year employee of the dealership and our diesel techs are chomping at the bit to get there hands on the ED to diagnose and learn, so it got done pretty quickly. The tech ordered an EGT sensor just in case that comes up again later. What's odd is that the gauges never faltered, oil pressure was dead center of the gauge all weekend, my tech did comfirm that the digital readout is bs which had been said here in the forums, and oil temp was also normal. So doesn't look like any issues other than teething pains so far.
