I too retrofitted power fold mirrors to mine but removed the puddle lights as the mirror covers were a different color. I will potentially reinstall at a later time if I decide to have the mirror covers with the cut-outs painted. There is a coding parameter than needs to be checked as "aktiv" in the LCM but not sure if that option is available in the LCM3 (used through MY 2001) but do know for sure it is in my LCM4 (retrofitted auto lamps to my 01 so LCM4 was required). There is also a coding parameter for power fold mirrors in the GM3 but not sure what that actually does as they worked properly PnP (possibly keeps them from folding if a certain speed is exceeded. I know for sure they do not unfold automatically when reaching ~25kph as they do in my X6).
