Hey all,

Ive noticed an issue recently that when I unlock my car the passenger side mirror will move (way out to the far right). I thought most likley this was based on the key memory programming. As for some reason I just always used key 2. I grabbed key 1 and programmed everything (all three positions to the same position). I noticed it still will once in awhile move the mirror on unlock. I have tried leaving the mirror control in different positions (I typically leave it in the middle position).

Any ideas?

I am happy to read this. I have the same unexplained phenomenon. However, I was able to solve it by locking the car in such a way that the interior monitoring and other power-hungry aggregates are switched off. You press the fob twice briefly one after the other. This is acknowledged by a long flash instead of twice briefly. then there is peace with the mirror. It only solves the symptom but that's enough for me in this case. ;-)

Check if the mirror adjustment selector is set to right side. Flip it to the middle if not. Control if the movement stops.

I will try the couple lock trick. It is very odd tho as it doesn't move if I drive the car within a day or 2.. If the car sits for a week then I notice the mirror move.. But I'll try the double lock trick.. I also leave my frunk popped and hooked to a tender pretty much all the time when I know it may sit for more than a couple days

Well car sat for a couple weeks while I was out of town for work and came home and the mirror didn't move on unlock this time (after the 2nd lock).. There has to be a reason why this is happening and a way to fix it.

I would appreciate it if the cause could be found, i have given up and use the double lock trick, also for energy and battery life reasons.

A coupla things. First, the mirrors are programed to the key. Reset the seat/mirror memory for that key. I forget how... start your car, and set up your mirrors and seat etc... then hit the Key memory button on your door and hold it until it beeps. Read your manual for this as I may have forgotten something.

Your side mirror adjustment switch, the one high on the door, check to which mirror it is set to... left, null, right. When it is in the right position, your passenger mirror will behave differently when you put the car into reverse... something to check out.

This is how the .2 car works, I think the .1 is the same.

Thanks Bruce, that's all clear and tried several times. No error codes. The problem is that after a time of not using of the car, the mirror moves erratically after unlocking. Sometimes more, sometimes less, sometimes not at all. The only thing that helps is double-closing. And since i always do that anyway because of the battery, it doesn't bother me anymore. It's weird.

Maybe unhook your battery for a few days.... just a shot.

Programming as such is not a perfect science on the 997 - and since my 2006 C4s did not come equipped with the key programming module on the drivers door (for whatever reason ?? go figure ? ) I found that the best and only way I can program the seat and mirrors to my liking without having to go to the dealer every time for programming would be by using my Foxwell NT520...... I can set key 1 &2 the way I want them and my memory preferences are stored permanently.

What menu is this in? I have a high end autel unit that does plenty of programming and I also have a PIWIS unit.. Maybe I can try and program everything the way it is to key 1 and key 2 and see if the problem still exists

My guess is the position sensor in the mirror is messed up. Key #1 is linked to button #1 in the seat memory: when you unlock the car it adjusts the seats and mirrors. If the sensor is faulty then it thinks the mirror is in the wrong place and moves it.

I had a similar problem with my lumbar support, where it would fully inflate the support. My fix was to clear the seat memory, leave #1 blank, and program my seat & mirror positions in #3. That way it doesn't auto-adjust when I unlock the car, but I can still get the position back by manually hitting the button if it gets moved.

This wouldn't bother me at all clearing all the seat memory as I am the only one who ever drives my car. Is there a procedure for clearing the seat memory? I will check my manual but read some conflicting information online that seemed confusing.

Thanks

For MK1:
1. Switch on the ignition with the vehicle key (you want to delete).
2. Press the memory key twice and key 1 once in succession.

I didn't know about pressing the key fob twice & long flash procedure. How exactly does it differ from the usual one press - what's activated and what's not?
