one-touch all windows up/down
I was thinking yesterday about how cool it would be, indeed, to have a one-touch up/down button for all 4 windows much like the convertibles have. I dunno about anyone else, but when I hop in the car the first thing I do (weather-permitting) is get all 4 windows down with 4 separate switch hits, and then bust open the sunroof. That's 5 switches! (I'm lazy, so what?)
Can someone post a picture of where the button is (I've forgotten) and if anyone has any information on the parts necessary to connect such a switch, that would be awesome too.
I can't imagine it could be anymore complex than that, although I wouldn't be floored if it was some function built into the ECU or some other integrated device somewhere.
Comments? Suggestions? Originally I thought about how I might emulate the button on the key (that remote auto-down feature) and then my intelligent self realized that you'd also need to emulate the key's security system... not exactly easy!

ditto
yeah i hear ya, i was thinkin of the same thing recently
:dunno: dunno how to do it though, anybody?

The first thing I do on a hot day is hold down the "open" button on the keychain to make all four windows and the sunroof open. So you have a one-touch down button already. Unfortunately, once you're in the car there's no one touch up button and there's no way to close all the windows with the fob, unlike Mercedes.

Re: Re: one-touch all windows up/down
I've held down the open button on the remote to my 2002 325i sedan for a loooong time and nothing happens .
I can open all the windows and moon roof with the key in the lock (turn left and hold for a little while).
Is this a key programming thing that I somehow missed? Perhaps only available on 330's or just coupes? I'd just about kill to have the remote open all the windows :bigpimp:

Re: Re: Re: one-touch all windows up/down
Press unlock once for the driver's door then twice and hold... about 3 seconds and the windows will lower. It works on the 325s:thumbup:operknockity said:

Click unlock once to open drivers door, click unlock again to open all doors, then hold down unlock till all windows and moonroof open.

Since all the switches are on the center console you could wire them to all activate at once. The convertible has such a switch so if one had a wiring diagram it should be do-able. For the sunroof you'd have to wire in that switch too which would mean snaking a wire down to the center console.

It's easily done if you know what you're doing. Ron Stygar, a regular on this board in the Z-forum, has done all kinds of similar projects to BMW's. Check out this one for instance: http://www.unofficialbmw.com/e36/interior/e36_second_sunroof_switch.html
He actually added a sunroof switch to his center console so that he doesn't have to reach up. If something like this can be done by a shadetree mechanic, I don't see how yours would be that difficult.

Thing is, E46s are FAR more microprocessor and bus based than any E36. Yes, E36s have 'body electronics' systems as well but not nearly as much as E46s. I'm not saying its not possible; just that it's likely tougher on a E46 vs E36 (or earlier)

Probably. But considering that the feature does indeed already exist on another E46 is promising. I'm sure a little tooling around in the Bentley manual could get you somewhere.

man while the key button open works for me, i have to be ridiculously close to the car. and it doesnt always work. does anyone know where teh receiver is? i need to point that mess right at the car and be like 2 inches away... )=ObD said:

One very simple trick is to touch the metal part of the key to your chin while pressing the button. This will give it a good deal more range.eugeneDC/TX said:

The antenna is in the rear glass.
Mine works as far as the normal lock/unlock does, that's to say a dozen or so parking spaces (100ft?) on a good day.eugeneDC/TX said:

hmm, i'll have to try it again some day. i gave up on it cuz it never worked unless i was up close, which defeated the purpose cuz i'd be outside in the heat trying to get the windows open for longer than it would take me to get in and do it myself. (=Kaz said:
Re: Re: Re: Re: one-touch all windows up/down
Tried this sequence on my way home tonight and I was greated with all the windows and the moonroof open :thumbup: :thumbup: :thumbup:. I was holding the button down on the second press rather than the third. Guess I shoulda watched the video that came with the car :banghead:.ObD said:
Re: Re: Re: Re: Re: one-touch all windows up/down
Ancient chinese trick. Touch the key, metal portion, to your chin, press button. Greatly increases the range. Reason you have to be close may be a saftey feature to verify that you really mean to do the intended action.eugeneDC/TX said:

Makes your fillings tingle also.........(J/K)johnlew said:
Looking in the bentley, it would not be as easy as you might think. The switch is not connected to the window motor. When you lift the switch it sends a GND to the body ECU to lower the window. if you pull all the way up, a second GND signal is sent to the ECU to activate the auto up and down feature. There is a seperate ECU input for each window.
Well, I was looking in there too, and you're right, its not that simple. However, if the GMV is the same unit, one would have to figure out which line is the one that gets sent to ground to run the all-windows feature.
The electrical diagram (ELE311-313 I think) don't show the separate convertible switch, so its hard to say if a swap to the convertible's window switches will just work.

Well isn't this just a huge mess of information, thanks guys. I guess my aspirations for being the laziest accomodated BMW driver there is will never be realized. Oh well.
I like the idea of emulating the 4 window switches with one switch... since the ECU doesn't limit you to rolling up/down one window at a time, I see no reason why you couldn't rig something up to handle that for you. Maybe some center console disection is in order for me one of these weekends...
