Is there anyway to program through SDS to have mirrors fold when locking door with key?
Its not an option in the instrument cluster?

Some years/models have that option, other do not. Your owner's manual should discuss it. Also, some owners have discussed this matter on the forum - a search may find the answer.

Thanks, I have looked and done a search but nothing I find is specific to my question. All I find in the manual is attached. I recall in the W211 that the upgrade of the front SAM was necessary and SDS programming but I still cant confirm this for S class

Check your front display on your dash, move through the set-up screens if it is not there you do not have the option.
