Bimmercode to close mirrors on lock in a convertible?

[balloony]

Hey,

Thanks to you guys I read about Bimmercode and some other options. But before buying I checked it out.

But it said you can't put the electric mirrors in and out using the key fob if you have a convertible. That doesn't sound like it makes sense.

Does anyone know if that's possible?

Also does anyone know if you can switch on intermittent wipers somehow?

The last thing I find a tad annoying it the indicators are like an on/off switch. I have to manually turn them off. Is there a way to change that?

you can close the mirrors on lock but not open them via keyfob. You have to code the car, I managed it but after a few goes i changed it back as these wing mirrors are not designed to move in and out so often.

And of course it would only work if you had folding mirrors which seem to be one of the less common options

I hope that you don't mind me asking, but surely folding mirrors are designed to move back and forth?

I gather he means they are quite delicate so opening and closing of the car and the mirrors doing it everytime will probably result in excessive wear.

The folding mirrors on my early 2004 z4 are great but they don’t fill me with confidence. They even sound a bit arthritic.

Thanks for clarification. You do have a point, mine still sound okay. 2006 E85 3.0si

The end points where mirrors stop moving is metal on metal. One stop uses a sliding pin on one direction and the other direction the stop is metal butting up against metal.

Let's say the folding movement in either direction is 5 seconds, I haven't timed it. When the window switch button is pressed the powerfold module sends power to mirror for 7 seconds. So there is force sent to the mirror for an extra 2 seconds once the mirror has made contact with the stop. Is this enough extra force sent for an extra 2 seconds enough to cause damage? Who knows.

The electric motors in these mirrors are quite common and are very similar to motors I have found in my child hood toys, scalextric cars etc. They have high rpm but are low in torque. The mirrors use cogs and worm gears to slow the motors down and create torque. Would this still be enough strength to bend metal?

You could argue that constant folding and unfolding is better as it stops parts becoming seized. The pin can have a habit of being stuck in the up position, so constant use would help keep it free.

The internals parts of the mirrors are not exclusive to BMW, they are made by another company and are used in many German cars.

I have used parts from an Audi A6 to repair the Z4 powerfolds. When opening up the Audi mirrors i did notice they used microswitch's for the end points which is different to BMW.

I found the intermittent wiper button

Interesting chat about the mirrors. I always put them in because I don't want someone to take them off, but perhaps I should stop. although I'm guessing Usel is saying it's not an expensive fix anyway, in which case, my love of tinkering will probably mean I do it.

I can handle pressing the button for opening them, it's unlikely I will forget to do that lol.

Even if you do forget they will fold out on their own at (I think) 10mph

No way, then I almost won't care about remembering. I guess I'll probably need to check the mirrors to pull out lol.
