I'm going to have the dealer program the cluster to my car tomorrow and I'm guessing that will make the correct mileage pop up. I may try unhooking the battery first to see if that fixes it. There is a lot to remove to get to the cluster, it's not the easiest cluster to remove. I can post pictures of what had to be removed if that would help. There is only one plug on the back and it's exactly the same as the one on the base cluster. If not for the mileage not showing up I would drive the car as is and just dismiss the warnings at startup.Wow! I can't believe it was that easy. Did you try unhooking the battery for a minute to see if that fix the mileage issue? And also, how did you get the cluster out. And is there just one plug-in on the back? Details details please!
