Wrench light and more

Few days ago I got my first wrench light on a cold start drove it to the store then back home(about 2 miles) didn't notice any power loss. Light came on about 1min and a half after cranking. I killed it then started it back up wrench light was gone. Two days later I drove it to down the highway to a job site it sat there for about 2 to 3 hours then I started it back up engine was still warm 2 minutes later while accelerating wrench light jumped back on (no power loss that I could tell). I decided to pop the hood and I found that underneath my turbo there is a oil leak couldn't tell from where either. Also I decided to check the egr valve it was slightly dirty but inside the manifold very very small amount looked like some goo. I'd say about 95% of the what I could see in the manifold was dry. So I might have caught my egr cooler at an early stage leak. But what i'm mostly looking for is more trouble shooting tips on the wrench light.

You need to have it scanned on live data and do a data log by someone who knows the 6.0 to see what is setting off the wrench lite.

The scanners at autozone and others do not read memory codes. You need a good scanner that can read memory codes. Could be EGR min stop code, turbo overboost, or possibly FICM issue. Oil cooler deltas will set a code too but after a min and a half I wouldnt think it wouldve been warmed up yet. Memory codes will tell you.
