    Any auto dimming rear view mirrors? Retro fit guide fitting.

    Any 8l have the auto dimming rear view mirror fitted as standard? I've got the hole set up off a bora, including the rain sensor, wiring relays etc for 20 quid and all in black... Any one retro fitted one?

    Any auto dimming rear view mirrors?

    I've got one on my 2002 S3. Great when you have a big 4x4 sitting up your chuff at the traffic lights.

    Pretty sure I've got one in my 2002. Seems to have a sensor in the front of it pointing to the rear of the car. Never noticed it before this thread don't even know if it works lol

    There should be a fuse for it,check fuse 5,other than that there are three wires to the unit, ignition feed,blue/black,brow for earth and the last wire is for reverse cut out feed.

    To check the operation,cover the sensor in the front of the mirror with your finger and shine a bright light into the front sensor (ignition on) and it should dim quickly

    Ive always moaned about dazzling lights behind me,so when i got offered a black mirror ,wiring replays etc for 20 quid i jumped at it...its all in and works a treat,love it!

    First is the button on the screen that attaches the original mirror,its a different fitting and i know if i try to remove it it will crack the glass,other option is to buy a new later screen...but not yet

    Original twist fit mirror below,auto dim on top.



    original non dim mirror button.



    The Auto dim mirror has a 20mm hole in the center for the auto wiper option,for now im wiring it in but not fitting it unless i change screens,so it will be in the glove box if need be,the auto dim button fits nicely over the original button,so i bonded it on.

    Few ours later...



    view from the rear..



    Next was the wiring,i took no shots sorry,but it soldered the blue/black wire into fuse 5 and gave it and earth,the reveres option i left off,the wiper wiring i wired into the back of the wiper relay and all done.

    The original mirror sits higher than auto dim mirror,so the tube that runs the wires through needs to be trimmed down.

    Before trimming.



    and after...



    Then just slot the mirror in place,connect the plug,fit covers and your all done.



    still need to order the lower trims so please ignore..



    So if i ever change the screen for an later auto dim mirror type all i have to do is pop the rain sensor in place,plug the wiring in and done....probably never happen lol

    enjoy

    they share the same fuse and its the fuse board on the side of the drivers side dash,i suspect the mirror is at fault if it has all its feeds?

    edit,its fuse 8
