2007 BMW Memory Seat Issues
 

Sometimes when I use my Key--versus my wifes--the seats adjust to my setting but not the side view mirrors. It's not always but it's more often than not. Then I have to hold down my number to get the side mirrors to my setting.

Automotive electronics is not BMW's area of expertise.

Welcome to BMW key memory............. my 5 does the same thing even when i use my key every time. The mirrors seem to wonder around. BMW has had issues with mirrors and key memory for years now.... it was really bad in the early e53 x5s

My 04 X3 is even worse! The mirrors never sit at the position you want it to be memorized. Recently all of the power windows fail out of no reason and the mirrors fold down without command. After BMW service check, they replace the driver side mirror then all the function work now.

Do you lock the doors with the remote everytime you leave the vehicle? Because if you don't, it may confuse the car as to which settings to recall. Think of it this way:

Lock = save previous settings.
Unlock = load previous settings.

Whenever my dad confuses the car, I simply go back with both keys and resave the memorised settings. Unlock with Key 1, push seat memory M1, lock. Unlock with Key 2, push M3, lock. Then I unlock with Key 1, and it goes back to M1.
