FWIW on an E53 the mirror positions are stored in the seat memory (like on an E70). And even though the mirrors can get seriously SNAFU'd, the seat memory will get them back into the correct position BUT.... this will NOT be remembered the next time you unlock an E53 UNLESS you lock the X5 with the physical key. IOW on an E53 you can reset the mirrors using the seat memory button and force the E53 to remember these settings if you do NOT use the electronic key to lock the X5. If you use the electronic key to lock an E53 it will immediately adjust the mirrors back to the SNAFU'd settings (which presumably were stored in the key) - DUH.

Yes I know this sounds insane. But trust me, this trick does work. I have nearly 95,000 miles over 8+ years of experience to prove it

Now does this trick work on an E70? I hope I never need to find out.
