Can anyone explain to me how do the various mirror options on E92 work? I have a 2011 335is, which came pretty much fully loaded as standard. I have options:
S430A Interior outside mirror with auto dip
S431A Interior mirror with automatic dip
S459A Seat adjuster electric with memory

Plus, there is a note on realoem somewhere, that "Special option SA 430 contains SA 313" S313A is "Fold-in outside mirror".

I need to buy both door mirrors (both were damaged and previous owner replaced them with pre-lci mirrors). I understand I should be looking for 3-pin ones, with auto-dimming and folding options, but I have some doubts:
- are all 3-pin mirrors electrically folding?
- are all auto-dimming mirrors also electrically folding?
- my car actually has 5 wires going into the plug? Why? Are two of them unused?
- if the mirror is electrically folding but not auto-dimming, can the glass be simply replaced and connected to get a fully optioned mirror?

I tried solving that through realoem, but it's traditionally very confusing when it comes to mirrors. I'm seeing multiple part numbers with seemingly same options, see for yourself:

Can anyone help?

Problem solved - I bought a pair of 3-pin, power folding and dimming mirrors, plugged them and everything works.

But, for the mystery of 5-cables going into my plug - I checked the passenger side, and there are only 3. There is a chance you are right, ptpending - seems like this part of the wiring (between window/mirror switch and mirror) is from 5-pin car. But why? No idea, no record of the door being replaced or damaged, but who knows.

Can you tell me the P/N you used? I am having the same confusing problem with RealOEM. Thanks!
