it seems that this issue may have been mitigated already - when you pull the key out, the mirrors fold. when you put the key in, the mirrors open but you can fold them AGAIN using the stock fold button. and then, pull out the garage, and unfold them again...

at least, this is how i got this pictured in my mind...

As promised here's the wiring diagram ( a little confusing but it's as simple as I could make it look)

I'll try and explain it.

The 5 pin relay is fed permanent fused power to pin 30 and when the Ignition is switched on the relay switches to pin 87 activating the 2 timer relays which only power up for 12 seconds before switching off and when the ignition is switched off the 5 pin relay switches back to pin 87a which fires the timer relays up again for 12 seconds before they shut off again.

The timer relays when triggered one feeds earths to the DPDT relay but each side of the switch at opposite sides and the other timer feeds the power (12v) to the DPDT relay each side of the switch again at opposite sides this allows the switching of the polarity down the 2 wires.

The DPDT relay when not being switched by the switched ignition it feeds the positive and earth to the mirrors one way round for just 12 seconds ( fed by the timer relays) folding them IN then when the Ignition is switched on it activates/switches the DPDT relay and this then feeds the power and earth the other way round to the mirrors folding them OUT

Best part is as the timer relays only feed power and earth through the DPDT relay to the mirrors for 12 seconds then the wires have nothing fed through them till the timer relays are next powered up, so the switch inside the car the can still be used to manually fold/unfold the mirrors and there is no back feed issues.

Nice work man!

I did remote controlled power folds on my E38 and love it!

As TerminatorX5 said due to the timer relays only powering the mirrors for 12 seconds then the wires fall to nothing so the original switch inside the car can be used with no issue with back feed.

Nice,

I think this is how it would work if you install the intravee module which I believe costs £150 GBP,

I went to wire mine up using the output wires from the central locking control module but they pulse so quick I would need a different type of relay which I didn't have, but if I was to get the correct relay It could easily be wired to work off the remote locking.

Marvelous!!!

part numbers for the relays? (since you already listed the pins for the relays, might as well use the same relays)

the WDS puts those mirror motor wires into the door module area... i have those wires at pin 3 (red/blue) and pin 10 (green/brown) of the door modules connectors - same pins on the left and right. WDS does not differentiate between LHD or RHD.

Nice job Sir

Thats correct pin 3 and 10 straight off the back of the window switch units.

The relays are as follows (obviously Im in the UK so it would be easier to source the same product from the States)

wow, that omron relay is some serious ass relay!!!

thank you very much for the part numbers, thank you for the schematics - this one definitely goes on my to-do list (http://www.xoutpost.com/bmw-sav-foru...done-list.html)

Sorry I posted the wrong link to the DPDT relay

I'll modify the other post....
