Can't wait to get my tools and scanner as I feel there is much more in this car that has been messed with to make it work. *Note: I and the car are located in South Africa -- a right-hand drive country that has some XFs, but not many. Assuredly, parts are scarce locally, but Mercedes is here big time. Also, I have access to all US suppliers so can order what I need from them, ebay, etc. as long as the things are not made only for left-hand drive cars)

Will need to explore why none of the locks work. Am relieved to hear that they should all work in unison and look forward to getting them back to original working condition.
