DIY: E70 Passenger Door Mirror Motor

This DIY covers replacing the passenger side door mirror motor on a 2009 X5 35d with Comfort/memory seats. More specifically, replacing the Magna mirror motor BMW part number 67-13-6-973-724. This fixed the issue with our passenger door mirror not lowering when in reverse.


Note the Magna mirror motor part number 67-13-6-973-723 does NOT fit E70s with comfort/memory seats. They look similar but the electrical connections are very different — part number 67-13-6-973-723 are recessed and part number 67-13-6-973-724 protrude from the body of the motor housing (Photo 1)

Tools:
- Thin piece of plastic/wood
- T10 with a long shaft
- 2 very thin bladed screw drivers
- 1 medium screw driver

Procedure:
Step 1 — Remove the mirror glass by prying it off of the mirror motor. The mirror glass is very pricy So I placed a box with a towel under the mirror area just in case. I used a thin piece of wood to gently pop-off the mirror glass working my way around the edges. Most likely the mirror motor mounting plate will remain attached to the mirror glass. See step 6 for how to remove the old mounting plate from the glass. There are several youtube videos online of how to remove the mirror glass if you want more details.

Step 2 — Unplug the heating harness. I had to use a very small jewelers screwdriver to release the catch (Photo 2)

Step 3 — Remove the mirror motor using the T10 on the 4 screws (Photo 3)

Step 4 — Install the new mirror motor

Step 5 — Test the new mirror motor— in-out, up-down, and reverse

Step 6 — Remove the old mounting plate from the mirror glass. This is a delicate operation. So I did it sitting at a work table with good light. There are several tabs on the mirror glass that need to be pried away to release the mounting plate. Start with a pair of tabs that have a slot midway between them. This slot allows you to pry upward on the mounting plate with a medium screw driver while the two thin screw drivers hold back two of the tabs. The remaining tabs are much easier, as you work around the mounting plate one tab at a time. (Photo 4)

Step 7 — Plug the mirror glass into the heating harness

Step 8 — Gently press the mirror glass onto the mounting plate working your way around the glass. Check to see that it is firmly seated before you let go.

Step 9 — Double the check the full operation of the mirror motor — in-out, up-down, and reverse.

Note: there are 2 manufacturers of E70 mirror motors — Magna and Eaton. You may want to check your mirror motor before you order any parts.

Hi @FunfDreisig,

Firstly - Thank you VERY much for taking the time to make this informative post. The passenger mirror motor on my wife's 2012 non-diesel "fünfunddreißig" X5 has given up the ghost., so I am ordering parts and prepping for the surgery.

This doesn't seem too bad. I was wondering why you need to do Step #6 - it seems like you remove the mounting plate only to re-install it? Does the new motor come with a new mounting plate, is that why you are doing this?

It also seems like you may have ordered the wrong part.....Is REALOEM a good guide here, or do I really need to disassemble the mirror twice (once to figure out which part to order and once to actually replace it).....

Thank you again for your work - and no worries if you can't recall some of these details from like 4 years ago, pre-pandemic!

I think it's because of this:

Also, having done this recently, I can say be verrrrrrry careful with the glass as you can easily destroy the auto-dimming film (if you have it) inside the glass, even if you don't crack the glass. Some slight flexing will do it and then you have to replace that too.

One other note, I would test out the operation of the motor BEFORE you re-attach the glass. That way, if you have any issues or need to troubleshoot, you don't risk making it a more expensive repair.
