troubleshooting 6.0 turbo - Diesel Forum

here is my story.
I have a 2003 6.0 with an afe cold air and edge programmer. At 90000 miles the dealer changed out the turbo stating rust and not the usual coking,
Now I am 117000 and I have turbo woes. Lack of power, coughing thru the intake and a lot of black smoke, happened all of the sudden after ildeing 15 minutes or so,I have been told my diesel mechanic turbo is bad just by hooking a scanner up to it once. Took it to another and we started checking all the periphal stuff. MAP sensor, expressure, and toook the edge programmer out and the system and worked fine for a week or two, then after a 5 minute idle, the same problem again. more checking and we have orderd a new turbo. On a hunch after reading a thread about VGT reset, I pulled both battery cables for 5 minutes, re hooked and now the truck runs fine again. Got any info on checking VGT or am I looking at a new turbo either way?

Inferred ebp, which your 6.0 has, is very touchy with exhaust leaks, intake leaks, and aftermarket products. Check your MAF sensor also, and clean it, as the oil from the filter gets on the wires of the sensor and lets dirt stick, causing false readings. Would recommend switching back to stock filter. Could also be a turbo....find someone capable of doing a proper diag. as there are many issues that will give symptoms you describe.

Will look into those things a.s.a.p. I just keep trying to apply logic to all this, what would cause it to go into deep six after ideling for a little while that reseting would cure. I don't want to just throw parts at it, can
t afford to
