Check your turbo outlet pipe.
Had to call roadside assistance today...(read my Coach-Net post).
Just wanted to let others know about my experience. Cruising down the highway and all of a sudden the low air pressure alarm went off and I lost all air pressure in a matter of a minute or two. Upon inspection, I found the outlet pipe coming from the turbo had broken loose and had moved about 4 inches forward leaving a large gap in between it and the turbo.
The tow truck driver found two air lines with holes melted into them. These lines are a good foot away from the loose turbo pipe and no where near anything hot. The lines were wire-tied to clamps in between the frame rails and were not rubbing anything.
The only thing the tow truck driver and I can figure is that the intense heat coming from the gap between the turbo and pipe was enough to melt holes in the plastic air line.
The clamp was still on the turbo, but the flange on the pipe had broken off in several places and allowed the pipe to slip off the turbo/clamp.
The interesting thing is that I did not notice any change in engine noise or loss of power with that pipe disconnected.
Just thought it might be wise for other dp owners to check for looseness of the outlet pipe on the turbo, or faulty clamp...(the clamp looked okay)although we didn't try to tighten it since the flange was missing anyway.
If the repair shop finds anything that doesn't support mine and the tow truck drivers theory, I will let everyone know.
Anyone else have a different theory? Also, has this happened to anyone else?
