DIY: F20 F21 Power Folding auto dimming & dipping mirrors
Hi guys,
I'm new at the forum and I drive a BMW F20. DISCLAIMER: As with all DIY projects, undertake this at your own risk. I am not responsible for anything that happens to you or your car! I did the power folding auto dimming retrofit with dip function to my F20 - I want to share that with you - and by the way - sorry for my english, I'm not a native speaker. Basis: F20 118i 11/2011 normal heating mirrors auto Timing back mirror Needed Parts: - 2 x Mirror with power folding functionality - new switch for the mirror control with the folding button Tools: - shrink tubing - soldering colt - Torx screwdriver - plastic tools for the door covers Background: The mirrors in the normal setup where directly connected to the switch on the driver side. So they are directly controlled. In the new setup they are Controlled via Lin BUS. These are basically the differences. On the driver side, Lin Bus is already there - on the passenger side not ... Opportunities ? Later more ... Steps: 1. lower the Panel on both sides and put the mirror glas on both sides in the upset possible position. 2. disconnect battery 3.remove both door covers. (some torx screws, use a plastic tool to remove them safely). Dont kill the metal clips at the top! 4. remove both inner doof frames where the small speakers are located. The frames are also tightened with clips. 5.Remove the mirror glas with a plastic tool from the bottom. Lever it towards yourself slowly. Reattach the tool several times around the glas. Afterwards remove the mirror cover. It is tightened at three points inside the mirror with some kind of plastic clips. Four hands instead of two helped a lot here Two hands try to loosen the clips, the other two should try to remove the cover. Same for the other side. 6. Now it is possible to remove the mirrors. It is tightened with three torx screws (one is hided unter some rubber). Loose the mirror connector plug first. 7. Mount the new mirrors in the same way you removed the old ones. Plug in the cable. 8.Now the mounting is finished. Driver side is plug and play, if you replace the switch ... Because Lin is already located there (you remember - I mentioned this before) But what is about the passenger side? So I did some research in the Internet and in Rhinegold and I started to wondering what happened with the three cables which were used in the old "normal" variant? You are guessing right - nothing. So they will remain useless. But - how many cables do we need for getting the passenger mirror working? - We will need three of them. Perfect - this sound ideal. One little problem is the cabel profile - it is not the same than in the original wire ring diagram. But from my point of view - this is not a big problem. Not much power running through it. So - we are able to proceed: 9. Following steps are needed on the connector of S35 (at the passenger switch) Pin 7,8,9 are the useless pins which where directly connected to the passenger mirror. I've opened the connector and connected the following pins with the soldering bolt. ( you can do it how ever you prefer ... ) Pin 7 mit Pin 1 (ground) Pin 8 mit Pin 2 (Lin Bus) Pin 9 mit Pin 10 (power) You can see the disconnected cables from pin 7,8,9 and the connected cables to the mentioned above pins. 10. Put everything together 11. Connect Battery 12. Code: Add 430 to FA and code FEM VO Done Thanks and feel free to ask if something is unclear. best Tim |

Also got it working by following your instructions, however, i had to add the following two options with coding to get the switch button and dipping function to work:
ASP_BEIKLAPPEN set to aktive ASP_MEMORY_VERBAUT aktive |

bmw f 20 autodim mirror fuse location
Hi again, well i have installed an auto dim interior mirror, the coding is ok but the mirror does not dim, i am thinking if the problem is the fuse, so does anyone knows which fuse applies to the auto dim mirror, also can someone post a photo of the wiring from the rain sensor, actual photo so to be easy to check if the wiring is correct. Thanks a lot

I need to bumb this up. Is it possible to use the folding without a new switch?
And does the adjustment of the mirror still works with the old switch without the folding button |

Side Mirror Query
Just bought an F20 116d. Driver side mirror adjustment works fine. Passenger side mirror adjustment doesn’t work at all. However, passenger side mirror tilts down when reverse is engaged. The driver door mirror switch is fine as I tested it with multimeter. Wiring seems fine too.
Previous owner had replaced driver side mirror after accident. I suspect they installed the wrong mirror on driver side. I took the cap off from both and they both look different inside. Driver side has no module on the back of the motor. The mirror glass has only two black wires for heating. See two pictures below- Passenger side mirror has a black module on the back of the motor. The mirror glass has an extra wire connector (white). See two pictures below- Can someone please explain what’s wrong here? Should I change the driver side mirror? If yes, which mirror do I need exactly? |

If you choose to change your driver side mirror for auto-dimming double check you really have the function supported as the parts are much more expensive than what you have. You can find part numbers here: https://www.realoem.com/bmw/enUS/select. Well, it calls the mirror glass "auto dip", but it must be a spelling mistake (especially for my LHD left/driver's one)! Regarding adjustment, it looks like the signal from the switch doesn't reach the destination while the reverse tilting signal comes from a different source (the gearbox?), apparently. |

Did this retrofit a few weeks ago using this guide. Really happy to have power folding mirrors now. To my surprise the side mirrors happened to be auto-dimming as well which I now very much like.
Finding the power folding mirrors took me a while though. |
