Just wanted to thank Konigstiger for all the help in getting my rear panel cover issue fixed. It was the rear SAM, which I bought and had a tech install it. Although the part number in the DTB had been superseded, the number that came up was still not correct as I have the LED lights in the rear. When they input the VIN number the correct part number came up.

It is now working and again my thanks to Konigstiger and everyone who replied to the previous thread.
