  • How to fix folding mirror from over-folding

    Thought I'd make a thread on how I fixed my heated and automatically folding side mirror. A few years back I crashed the right side mirror into another car's mirror and the mirror folded in all the way. I folded it back but I noticed when folding it in it goes too far, so far it hits the window seal. Nothing wrong with that if you don't mind a notch in the window rubber that it makes over time.

    So for the past 2 years I have been stopping the mirror manually every time I lock the car. This year I finally got some time to investigate it.

    To open up the mirror cover I followed this thread: http://www.ds3club.co.uk/showthread....-mirror-covers

    1. First I pried the mirror part off using a inside trim/holster tool. I have heated mirrors so there are wires for the heater to watch out. Just tape the mirror part somewhere higher so the wires stay loose.

    2. Next, unclip the mirror cover. You don't need to remove the middle part for this. Just unclip all the clips that hold the cover on.

    3. Now unclip the the rest of the mirror assembly. It comes off in 2 pieces. Just follow the clips that keep the back part on first and remove the sensor in the bottom of the case (what sensor is it btw?). Then unclip the front part (the one in the mirror side). If you have heated mirrors you can't rmeove the mirror side half without removing the heater cables. I chose not to do that because I was worried they would not come off intact. So you have to tape the mirror and the other half together somewhere.

    4. At this point you're left with the skeleton of the folding servo and wire assy. For me the servo casing was broken so when folding in, it missed the pin stopping the movement. NOTE: I folded the mirror manually over the "unfolded" position to be able to access the crack more easily. It seems that this is a safety feature if the mirror hits something. Not sure if this is wise though so be careful!

    In this picture you can see the crack at the bottom of the folding servo casing:



    This is after the first layer of Plastic Padding Chemical Metal. I also roughened the surface next to the crack to make the padding stick to the plastic better:



    And finally after the second layer of the Padding. I had to do 2 layers because it cured so fast, literally in minutes it was impossible to work with. (You can also see the mystery sensor on the right):



    Here's a pic of the open casing along with the heater/mirror part hanging on a tape:



    So far it seems to hold. If it doesn't, I may have to disassemble the entire servo. There seems to be a few screws under the servo that are accessible after removing the casing but I'm not sure if that's enough to remove the servo without removing the entire thing from the door. I hope the padding holds, this fix was considerably cheaper than the 700 eur for a new mirror that I was quoted. Plus the work of course.

    I can't see the pics at work but isn't the mystery sensor the temperature one for the car ?

        Hmm well I thought the temperature sensor was near the nose of the car. You learn something new every day!

          I'm going to bookmark this, I think! My driver side mirror has been doing this, but I noticed this weekend that it seems to have started behaving normally again (strange, I know)

          Keeping this just in case it happens again!

            Okay, so today I noticed that my passenger side mirror was doing this i.e. Overfolding until it touches the car. I have just stripped it all down and can see no damage at all . When it closes the servo gets to the point where it should stop, almost stops, before it overcomes what ever is inside the assembly and continues until it reaches the window

            It is really easy to stop the folding action in the right place, with barely any effort from your hand.

            It seems to me that it may be worn inside the mechanism.

            I am under warranty until October but bought the car from Motorpoint so I should be okay to claim? Are the dealers okay with this do you think? I have had no dealings with Citroen up until now.

              I can't recall is the warranty passes with the car or the original buyer, I'm sure I read it in the owners folder thing so if you have that look in there and it should confirm for you. If not I suspect someone will be along today who knows

              Personally I'd try the local Citroen dealer anyway and see if they want to help....

                Local dealer had a look at the car today. They say it needs a new mirror assembly and are happy that the warranty is still valid. Will be getting done once the parts arrive.
                I just have to decide if I want them to delete the folding action everytime the car is locked and just have it when I press the button?

                  And you see no damage in the plastic? The crack can be hard to see if not pulled apart when it moves. It does sound like the same issue but I guess it could be that the internal pin or something has cracked.

                    UPDATE

                    The first fix didn't hold. The plastic padding was cracked right in the middle of the seam. So the padding did attach to the plastic, just wasn't strong enough.

                    So I dug and scraped the padding off, roughened the surface with 60 sandpaper and applied more padding and this time tried to get it into the seam as well. After a first layer I added a piece of fiberclass sheet and the covered it with more padding. We'll see if it holds!

                      I could see no damage at all......I was worried that the dealer would say I had broken it whilst driving (maybe hitting a parked vehicles mirror?) and so wanted to check it before I took it in for a warranty repair. They just replaced it, no problems and has been fine since.

                      Hope yours holds out, I think you can pick one up for £200-£300 if you look.

                      They also said you could not disable the auto-fold function overtime you lock the car, which seems to different from what I've read, but I could not be bothered to argue with them.

                        You can disable the folding is what I've heard. And I did find some after-market parts which cost around 100 eur and salvaged mirrors about 150 eur. If tha fix doesn't hold I have to consider replacing it. Still it's a pain to replace I think.
