My two cents here are probably worthless, but here they are:
If it’s NOT covered under 8/80 federal requirements, then ask the dealer to remove it, replace it with a test pipe, and tune it out. ask to renew your emissions and inspection stickers (if you have those) while it's in. They don’t have a problem enabling or disabling features with the starscan, so why not the DPF? when they say "because removing it is illegal..."
that'll be the sound of the light bulb going off in the service writer's head.
also have a real close read at your warranty's inclusions and exclusions. I'm betting it IS covered and they're just trying to backpedal to avoid paying for an extremely expensive mandatory band-aid.
i'd ask for them to get someone, anyone, to justify exactly how a turbo speed sensor killed your DPF. the late 3rd (and early 4th) gen trucks read MAP, MAF, IAT, and turbo speed all on the same channel with a less sophisticated ECM calibration and low-speed can-bus system, which they cross reference with engine load, exhaust pressure, throttle position, and the TCM to determine where in the fuel map the truck needs to be. they'll sometimes throw a code not for the actual problem sensor but the "odd man out" sensor, if that makes sense. I've heard of cracked injectors taking out filters and coolers, but not a redundant sensor. especially not one which gets cross-referenced six ways to Sunday by the ECM on a nearly real-time basis.
hope this helps, and I'm sorry for the run of bad luck. hope this helps (or at least proves mildly entertaining).
