I have the same kit installed and having a small issue with squeaking noise coming from the rear and went back to the shop who installed it and told me it was from the bump stops did you have this issue or noticed anything?
I had a Eibach lift kit done last month and didnt have any issues not sure if the shop disconnected the battery or not. It's horrible dealing with these dealership at times hope you find someone to fix it.
I'm going to try this had this error for about 1 month abd and the worthless dealership did the TSB update and said it was working. Picked up the truck and back to square one once more and now have an appointment to a different dealership.
