I'm experiencing some crazy issues, and wondering if it's maybe not my service department. Quick synopsis:

Purchased a 2006 F350 last summer with 45k miles (still under warranty)
Drove the truck from Florida to Minnesota with 0 issues
Took it to the service dept for a once over to make sure all was good
Had some minor engine items replaced under warranty (injectors, etc)
Was told that the computer was not programmed for this truck, and they reprogrammed it and flashed it to the latest update (Aug '10) Truck wouldn't start...
Was told there was an issue with the ECM and that it was the incorrect one for the truck. BUT the sticker on the side of the ECM was the correct part #. Could still not program it... They ordered a new ECM, installed it, put on the Aug '10 firmware, and the truck ran.
Didn't notice, but was told that I had the wrong gauge cluster in the truck. Interestingly, that was the only Ford warranty item done prior to me buying the truck. The fuel gauge wasn't reading correctly at 5k miles, so the dealer in Florida changed the cluster. Problem is, they put in a Gas cluster. Had the cluster replaced under warranty since it was a Ford dealer mistake.
Once the cluster was replaced, it now has an ABS light on.
Ford Service Dept reads the code and it is B2900 - VIN Mismatch.
Tech is having problems getting the proper VIN # programmed into the computer. Does the VIN need to be programmed into the ABS module?
They want to charge me not only for additional diag time, but also reprogramming time to flash it to the latest 2011 software.

Am I getting taken from the service dept? Seems that if the VIN number won't go into the computer, that it is something that should be taken care of under my engine warranty.

Does anyone know if the ABS, the computer, and the Gauge Cluster all get a VIN # inputted into them? Are there additional items that have to get a VIN # programmed into them? Why would the ABS light come up with a diag of "VIN Mismatch - B2900"?

Any thoughts besides take it to a new service dept and see what they will do?

HELP please. I have another service appt set up for Thursday, and if I'm not being treated correctly, I want to cut my losses now!

Thanks.
