difference between 3pin and 5pin mirrors
what's the difference between 3pin and 5pin mirrors? and is there a way of finding out which one i have without taking the mirror off?

Not sure, my 335 0n a 10 plate had LCI wing mirrors and I fitted a set of pre lci electric fold wing mirrors, unless there is a definitive answer from some one it might be a case of take them off and see.

There are a few things mirrors can have..
Heating Folding Dimming Memory I'd guess depending on those options depends what the pin count is. Then there are LCI and Pre-LCI mirrors too that probably differ completely again! |

I have a set of E92/93 M3 mirrors that are heated, power folding, power adjust and auto dimming and they have 3 pin plugs They were plug and play on my E92 335d LCI M sport apart from the auto dim which I didnt have on my car I had electric and heated seats
Hope this helps Ps the mirrors are for sale on the for sale forum |

3 pin mirrors use the LIN bus which is used by a module in the mirror to control things like heating, tilting when in reverse and the folding function. The footwell module sends commands over the lin bus to activate the functions.
5 pin mirrors are basically manual in that the heating and tilting function is controlled by the footwell module directly. If you take apart a 5 pin and a 3 pin mirror you'll see the lack of a control module inside the 5 pin mirror. Hth |

from other side M3 usually high packed car so you can have memory because you probably have electric seats
do your passenger mirror glass move down when you enable reverse gear ?

On my car I can fold the mirrors using a switch on the door armrest. I get reverse dip, but I can't fold the mirrors with the key fob. I have option 313. I found a description of the options as below. According to the description I should not have reverse tilt.
[430] Exterior and interior mirrors - folding, automatically dimming Electrically foldable mirrors Memorised adjustment controlling door mirror position Door mirrors ; light sensitive, door mirrors ; light sensitive with automatic tilt feature when reversing Heated washers Includes: [431] Rear-view mirror - automatically dimming Excludes: [313] Exterior mirrors, folding |
