Power folding mirrors

RR-NYC · 11-25-2013, 02:03 PM

I tried searching and didn't find what I was looking for so here it is...

I have a 2011 E90 M3. When I press the button to fold in/out the mirrors, they move at different speeds - One is slower than the other. I know it sounds stupid but it drives me nuts.

I took it to BMW Manhattan to look at and they compared it to another M3 and they both do it.

Is this normal?

No, not normal.

Edward · 11-25-2013, 02:21 PM

Yes it is normal. Happens on every mirror. The motors aren't different speed, it's just that the driver side has a further distance to fold up because its default position is winged out more to compensate for the assymetrical viewing angle as you sit in one side of the car, not the middle.

I'm 99% sure they open and close at the same time on my car.

Will take a closer look on mine later today but I think they are slightly out of sync. Less that one opens faster but more like one starts a half a second later than the other...

How is OP able to simultaneously put one eye on each mirror to determine start of motion?

Seriously, extend-fold motion should be at same speed.

Haha, peripheral vision!

There is about .5-1 second difference between the two

E90M3-SG · 11-25-2013, 05:15 PM

Both of my mirrors don't fold at the same speed. It's normal.

ZEEM3R · 11-25-2013, 05:35 PM

yeah that's normal. My car does that too.

MWM3 · 11-25-2013, 05:38 PM

mine does it as well

MMM3PWR · 11-25-2013, 05:39 PM

Everyone's car does it ..... Question is has anyone's mirror folding mechanism broke? No...

yes normal. driver side opens and folds slower. on mine as well.

RR-NYC · 11-25-2013, 06:11 PM

Thanks for the responses.

They both start at the same time but one side (Driver's) finishes later than the other.

e-solo · 11-25-2013, 07:20 PM

Normal. Never noticed until you brought this up. Now it will bother me too! Thanks! LOL!

Sandye90m3 · 11-25-2013, 10:02 PM

There was a post about this a couple of years ago, ever since I always look at the my mirrors folding at different speeds.

I don't know why...

burakkose · 11-26-2013, 08:01 AM

the angles are not the same, therefore the folding time is not the same ...

jphughan · 11-26-2013, 09:22 AM

How far off of simultaneous are we talking here? Mine aren't EXACTLY the same speed but it's not comically off either. The two windows don't roll up at EXACTLY the same speed either. I consider it normal mechanical variance. No two window/mirror motors produce the exact same power, just as no two engines do.

1MOREMOD · 11-26-2013, 09:48 AM

ive never noticed. dont get in the habit of timing them and you should be okay. plenty of other buttons to play with while they do their thing to distract you from the pain.

808@702 · 11-26-2013, 01:57 PM

Oh my god my mirrors don't fold at the same speed! Time to sell the car
