I'm upgrading my mirrors from only electric to folding and heated mirrors.
The original mirrors don't use the lin bus but the folding pair they do.
I've got 2 complete E90's sitting in the garage both from 2006.
The E90 which already has the folding mirrors they will be replaced by only electric mirrors.
My question is what do I need from the wiring to make it work on a E90 which don't has the lin bus? My E90 doesn't have power seats.
I'm not parting out only switch them.

Not sure how you would do it, but I'll guarantee you the cost is going to be over a grand.

I was looking into the cost of replacement euro glass for dimming and heated mirrors and the quote was over 750 just for the glass.

Not going to do dimming only folding and heating.
I do know that I've the add the lin bus on the E90 which doesn't have this option but what more?

Others have done it here, I know- can someone chime in who's done this?

lin bus (2 wires) from driver side switch to mirror
lin bus (2 wires) from JBE (passenger footwell) to passenger mirror thru door
switch replacement
option coding(required)

That easy?
Do keep in mind that I don't have power seats.

I ment that when you have power seats the lin bus is allready there.

Thanks

e90 seats do not use LIN bus at all

Can you explain why? I also have a E91 and there is a lin bus.
A customer of mine has e E90 335i usa vehicle and has lin bus.

[ptpending]

this is K-CAN bus
LIN bus in E90 is only for outside mirrors and adaptive headlights management

[Teq]

I'm going to install it in an E90 which has adaptive headlight but no folding mirrors.
Does this mean the lin bus is already there for the mirrors?

[ptpending]

lin bus will be wired to mirrors only if your car have mirror memory option or outside auto-dim mirror option
otherwise you need to wire lin bus to mirror from windows switch on driver side and jbe module in passenger side

Got it. Thanks
