I'm about to take this project on soon, and I was able find some of the pictures through web cache archives, so I've recovered and reposed below, what I could. If the OP can re-upload, it would be great, but this may be the best we can get:

Greetings everyone!

Some of you may be familiar with a common issue with our M5s where the side mirrors fold/unfold but do not stop in the proper position during their sweep. Sometimes the mirror will choose a random spot to stop, other times the mirror completely rotates upward or downward, only stopping once it reaches its mechanical limit. The temporary fix is to simply grab the mirror and manually snap it back into its detent when the other mirror is a full bottom sweep. I promise you this is only a temporary fix...ask me how I know.

Here are a couple example videos of what i'm talking about: (Video credit goes to their respective creators.)

This issue is also common with non ///M e6x and e9x with Magna mirrors.


The solution:

Thanks to our friend Troy Jeup for sending me some "R&D parts" ;) I was able to take a look into the root cause of this.


1. The mirror needs to be completely removed from the car to take it apart down to the level we need to. Pull the tweeter cover back above the door panel, and you will see 3 T30 bolts that hold the mirror to the door. Take them out, unplug the mirror and put the mirror on a bench.

2. Tilt the mirror glass all the way inward, grab it by the outside edge and pull it off the mirror motor. Do this carefully....there is a ribbon cable attached to the mirror glass you have to unplug.

3. Look for 4 small T15 black screws, these hold the front half to the back cover of the mirror shell. Take them out, and split the mirror case open.

4. Now look for 4x silver T15 screws, these hold the mirror motor clamshell to the rear mirror shell.

5. Now, you should have this:



Carefully remove xirclip circled in green off of the mirror spindle. You will need to reuse this so be careful not to break the tabs off! If you do break it, you can get a new one form your local home improvement store in hardware. Once this is off, you can access the internals of the mirror pivot spindle.

6. Separate the spindle pieces, but keep them in the order they were stacked!!





7. The black flat piece you see is a protective cover for the motor assembly. There are 4 tiny torx screws holding it on; take them out and remove the cover. Look for a little silver pin. (see the tip of the pry tool.)



See how the pin is stuck and sitting flush with the surface? This is BAD. This pin sits freely inside of a machined socket, along with a spring under it to make it spring loaded. What happens is, small debris gets into the socked and causes the pin to stick. The pin should be moving freely in its socket, and should be sticking out ~5-8mm in its natural position.

This is how it SHOULD look:




This little guy needs to move freely. You should be able to push him down, and he should spring back up with NO STICKING!

If your mirror isnt stopping, it is because this pin is stuck down. Flip the assembly over, and you will see a small in hold behind the pin on the assembly. You need to poke a small drift into the hole to pop the pin out from the back if you cant get it out from the front. Once you get it out, clean it really good and lube it up.






Function:

Unlike the e53 & e46, these mirrors do not use a micro switch to stop the motor.





Look at the above pictures closely. You can see that there are 3 little "ramps" and "divots" in the disc. The spring loaded pin rides on these "ramps" as the mirror is spinning. When the pin is stuck down, these ramps simply ride over the pin, so the mirror keeps spinning. When the pin sticks up, under spring pressure, it will catch one of the divots which are keyed with the disc as the mirror spins. The the pin catches the divot, it creates a mechanical stop for the motor, current spikes, and the mirror sees this as the mirror reaching its stopping point and cuts off the motor.

Clean everything up real nice and reassemble. The parts are keyed so they cannot be installed off-axis. Use plenty of lube on the swash plates too; it will quieten the mirror operation significantly!

Reinstall your mirror at it will work properly again. :)

Was wondering if anybody else had fixed their mirrors recently this way? Mine swings freely AFTER the car turns off. So I have the manually stop it once I get back to the car, but it still doesn't stop correctly so I have to force it to stop by holding it.

Can the mirror glass be taken off with it still attached to the car?

LMAO when i read of all this coding to customize and fold mirrors.

I just want mine to stay in the same place for longer than a day :grinyes:

KY?? :)

Thank you for fixing the pictures- there needs to be a better permanent solution to hosting photos :)

Would white lithium spray work for this?

Here's mine that is slowly getting worse. If it's a pin hard-stop, how would it slowly dip down over time? It seems like it should either stop the mirror if the pin pops out, or the mirror swings all the way around if the pin stays in. Is something possibly being wallowed out inside there that allows for this slow angled mirror creep? It doesn't look like much but actually affects the mirror alignment by over 10 degrees. I'm hesitant to bust this thing open but it looks like I'll have to. In the meantime I've rigged up a ghetto double-sided tape shim behind the glass so I can at least use the mirror while driving.

Yeah it rotates normally up and back down. Although coming back down, I hear some kind of small "pop" as it nears the stop, then it stops. I have my car coded to fold the mirrors upon lock, but I wish I knew how to turn that off, as I'm trying to minimize the number of rotations until it's fixed.

Well, found the issue. The pin housing is cracked and thus the pin stop is angled downwards, resulting in the downward angle of the housing. Great design BMW, with zero reinforcement around a spot that takes a large amount of force to stop the mirror. All of the grease was dried up as well.

BTW, Chariot, how in the hell did you re-compress that spring to get it down on the shaft? I tried and tried but could never compress it enough to get the rubber gasket and star-type lock washer back on the shaft. So the damn thing is taped, looks great. But hey at least I can see behind me again.

:nerd

Looks like you are going to need a new mirror assembly. Magna made these things for BMW and yes they are a design disaster.

I solved the issue with pressing the ring back on the shaft by replacing it with a ring. The ring has a couple of hex screws in in that bite into the shaft and keep the mirror on the car. For safety, to avoid an accidental slide off, I put a screw through it as well to lock it in place. I made a special copper piece out of water pipe to press it onto the shaft while compressing the spring and lock it in place. See the attached picture. This has been on the car (both sides, yes the other one will go as well...).

Nice job on the fix. I'm having someone de-code my "mirrors fold while locking" option so it won't wear on the passenger side too much. Now to find a salvage yard with an Interlagos blue M5 to part out...

I have bad news for you: If you code out the fold, it won't solve a thing. I had the fold up function turned off all along. And even though I got the mirror re-aligned after finding it dipped like yours, I found it back out of alignment the next morning or when returning from the office in the parking lot. Oh yes. After locking it, after another approx. 12 min the car falls fully asleep and when that occurs, I discovered (by waiting for it one day) that the mirrors blipped down at that exact moment that occurred! It blips up and down, but with the pin frozen it never came back up. I strongly believe it is either a software bug or some kind of poorly managed turn off (sleep mode) transient of the mirror motor / controller, e.g. the 'puck' with the electronics that holds the mirror itself. It is controlled over a LIN (K-LINE) bus and receives continuous power.

I am not sure if you are going to find an Interlagos blue mirror at the dump. You will have to break it off @Fiftytwoeighty car. :grin
