They called me later and told me that the vehicle won't be ready today because the update failed and the computer said that they had to replace the electronic gear shift due to fault.
They are overnighting it, but I'm concerned if my coding caused the issue. I haven't had any trouble with the gear shift, but could the i-step fail because of the 2TB that I added?

Cars with 2TB have a different GWS Module. When ISTA/P Program's Car with 2TB in FA, it expects car to have this GWS Module. Yours obviously does not have it, so it has caused what you have here now at dealership. The big question is what GWS are they shipping to dealership, non-2TB or 2TB one. If they go to ETK and order replacement based on your VIN, it will be another non-2TB GWS, which will not match current FA, you will have repeat of problem.
