The first thing you need to do is check your oil pressure level when the light comes on. If it drops significantly, then you either need to check your oil, change it, or have your service tech check the engine. Your pressure should be holding at 40 psi going up hills.
Interesting. Have not heard of this as an issue on any diesel with power loss issues.
Would be interested in hearing from anyone who has experienced a "significant" drop in oil pressure on their diesel (other than a gauge issue common to some chassis maker's gauge packages) which should not trigger the check engine light.
