Got the work done on my right tail light today. Didn't take them long to do the work. I saw the new housing and connectors and they appeared to be essentially the same as the ones they were replacing, so I have no idea what keeps it from happening again. They checked the left side and said no problems were seen.
The most interesting thing about the whole process was the reflash of the CPU. Took over an hour, and my service tech came and got me for the final portion. He asked if I wanted to see my car "dance." I had no idea what he was talking about.
If you have never seen your car run through its dynamic suspension test protocol, I would advise making it a priority. Holy cow! I cannot believe the car is capable of doing that. Came home and tried to find a video of it on YouTube and was unable to. I now have a much better understanding of what makes this car so special. Truly unbelievable.
