So got a call from the dealer today w no good news. They drained and refilled the tank. Started it up. Went straight into limp mode and was shaking like crazy as he described. They tried to scan it for faults and they couldn't get any communication w the DME. Tried all day long and still no communication. They feel they might need to replace the DME. They said they will try a couple other things tomorrow bs get back to me with the next step.
And the saga continues.
