Stubborn German

Mine is in as I type this for the second time and getting a new rear window installed per the TSB. The dealer service advisor told me that the new glass has a new part number and appears different from the old window; something about the curve at the top of the window? The TSB states: "If the vehicle underwent this bulletin repair, was released to the customer and later returned for the same concern, replace the rear sliding window. Refer to Rear Sliding Window Replacement in SI, AND ensure that during application of the urethane to the new window, that the urethane covers the complete length of the top encapsulation of the window." https://static.nhtsa.gov/odi/tsbs/2020/MC-10173388-9999.pdf They also did a DEF tank inspection and ECM update for the DEF heater under a recall. He said I was lucky, they have two trucks that have been waiting for a new DEF tank for ~6 weeks. I don't have the recall information yet as the truck is still at the dealer. I hope this is the final fix for the window!
