Check Engine Light
I had just got back in town after driving about 250 miles today in my liberty CRD. I had parked it and let it sit for about ½ hour when I started it up the check engine light came on. I have put about 4500 miles on the jeep with out any problems until today. I scanned the code and it showed P0299 turbo supercharger under boost and P0401 EGR flow insufficient. I went ahead and drove to the store and back with out any problem. Has any one else experienced this problem, or know what could cause this.
