Has anyone ever had this issue resolved? I've been dealing with P0128 off and on for 2 years with my 2016 Turbo. (It goes away in the warmer months.) I'm taking into the dealer AGAIN next week, and they don't have a clue. I have had the thermostat and temp sensor replaced. I also recently had the turbo assembly replace (separate error code). Last time they thought it was an air bubble in the coolant. Took less than 2 days for the check engine light to come back on.
I see a post with this same issue from 2018, but don't see a resolution posted. I've already been through everything mentioned in that thread. Any help would be amazing.
