Window Switch Coding ?
Hi folks
My cousins E89 has developed a fault whereby all the windows will drop when opening the roof and the passenger window will drop when using the passenger side window switch. However none of the windows work from the master switch on the drivers door, the mirror switch on this unit still works. All indications are a defective switch, but having tried the switch from another car it still fails to operate. We have been told by various electricians that a new switch will need coding at BMW, anybody have any knowledge on this.
I know there is a chance that it could still be the footwell module but starting with the obvious first
Thanks in anticipation.

Yeah, that's bollox The switch is just that, a switch. There is no module or canbus in it, just the switch (switches). The mirror side of it is separate to the window control.Strasse109 wrote: ↑Wed Aug 24, 2022 6:54 am ......We have been told by various electricians that a new switch will need coding at BMW, anybody have any knowledge on this....
Just as a matter of interest, did the replacement exactly match the original? Ie; was it from an E89 (or E93)?

Thanks Dave, confirmed my views that they were talking from the wrong orifice. Replacement switch from an E89 so fault must be elsewhere. Looks like a long road ahead with some testing of other areas.

I also have this issue. I was pulling a tinted film off my windows at the time and the windows all dropped and then didn't work with the driver door controls, but they will all drop and open withbtge roof mech as described above. I wonder if static elec was the cause as I pulled the film off.
I have seen some info on using software to reset the footwell module but not clued up enough to try it yet. Does anyone have a step by step guide? I have laptop connector and have downloaded various software

To reset the FRM is a specialist job performed by someone who knows what they are doing and with specific piece of kit. There are videos on YouTube that tell you what to do, but if you screw it up then you need a new FRM.
If the windows are operating in any way then I doubt it'll be the FRM that has gone. The drivers switch unit is all on a PCB, so it's susceptible to moisture being in that position so can short out.

We choose to go to on with this endeavour at this time and do the other things, not because they are easy, but because they are hard…

Ok thanks Dave, I'll keep an eye out for a replacement. Can you use e93 units or does it have to be e89?

I think it has to be an E89 specific version..

I have had the same, windows down wouldn't go up.
Connector in door, seems the negative pin bad contact, no illumination.
Clean connector with contact cleaner, made sure fastened tight, all good some several years now.

Update, I bought a replacement driver window switch from ebay, scrap yard say it is tested but it doesnt work at all.
Its worse than my suspect one, on which the mirrors still work.
The part is off a 2009 3.5i part #9180313, i have a 2009 2.3, part #9177822.
I see another e89 switch on ebay with part 9216107.
Are these interchangeable or do I have a duff part? All three of these part numbers are the version without folding mirror button.
I don't suppose there is anyone in north manchester has a Z4 I can test these switches in?
