After retro fitting the power fold mirrors with the switch module a few months back I always folded them before leaving the car but a few weeks ago both mirrors became intermittent responding to the switch so I decided I'd re wire them to auto fold,

so I set about investigating how there wired armed with my Power Probe I discovered the motors have 2 wire and there fed with a + and - to fold them in then the polarity reverses down the wires to make them go back out so I knew I'd need a dpdt relay (double pole double throw) I also discovered the + and - was only fed down the wires for 10 seconds or so before they became nothing so I then knew I'd need to source some timer relays and Id need 1 standard 5 pin relay to activate everything off the ignition.

So picked everything up and set about drawing out the wiring diagram (looked like spaghetti junction wires everywhere) after I checked and double checked everything for back feed issues and things i then set about hooking it all up, I managed to do all the wiring in the passenger footwell behind the glove box where the fuse box is located so I could tap into an Ignition switched + and a constant + and a - all one place and all I had to do from there was lay the wires through into the doors to tap into the mirror circuit.

Anyway here's the finished product:

nice, but cant you set that with the scanner or inpa

From what I could find out yes I think?????? but I think you need to hold the lock button on the key fob for 2 seconds to make them fold (to much of a faff if you ask me) but then I've also read that It's not possible on an E53 with out buying a £150 intravee.

Maybe someone who has actually programmed it can chime in with confirmation....

Very neat

Nice touch. I did think about doing this (and on previous models I've owned) but the thing for is the motor burning out with the constant folding in/out. Most of the time I don't need them folded, etc.

If you can get me a set at the right price I'll let you know....

Took mine apart and cleaned and greased all the moving parts before I fitted the mirrors when I performed the retro fit that said new gears are readily available cheaply for a rebuild.

Blimey they move quick, mine take about 3-4 seconds to fold either way.

Nice modification!!! I too would be concerned about wear and tear on the motors and gears but if they can be easily replaced then its all good. I need to open my mirror casings - is it as much of an ordeal as everyone says? I dont want to break any retaining tabs - can it be done without causing any harm? Are plastic trim tools the way to go?

Probably down to me stripping cleaning and greasing the mechanisms when I first got the mirrors before fitting them.

I didn't read any how too's when I stripped them down and I managed it with ease and nothing broke just gentle does it is all I can say.

Great little Mod that

Thanks,

In case anyone is interested in the wiring diagram if you fancy carrying out this mod here is how its done (click on the image to see it in full size):



and relays used:

2 X Timer relays

1 X DPDT relay

1 X Standard 5 pin relay

Tidy , i just had a quick count  and over a week with my work and weekend driving  if my mirrors were wired like yours they would fold out/in maybe 60 times , what happens in heavy frost can you override them if there frozen ..

Well I ran the same mod on my E39 M5 mirrors through 2 winters even in heavy snow and there was never an issue but if wanted a toggle switch could be fitted in the Switched ignition 12V then you could switch the mod completely off.
