New to the forum, but I've had my JGC since 2014. I purchased it brand new and it is my first diesel vehicle. I am in the Army and currently stationed in South Korea. So far, having a diesel jeep here is a nightmare. City traffic is terrible and I have to Regen at least once a week at 5am to avoid traffic. The language barrier is the worse and now I got my first P20EE code and incorrect DEF (I have used AdBlue since owning it). Wondering where to start with coding out the epa requirements and getting the most from my engine. I enjoy the site already!
