i was going to put it in 2001 B5 S4 without multifunction wheel - and just connect the wires for the telephone button - more i look the more it seems possible...anyways

i saw the part number for control module was Audi Part#: 4B0 907 487 F

what if i could get "E" module will that work?

thanks

brian,
you are going to need to consult the bentley manual for this. I have yet to see someone add a MF steering wheel to their B5 A4/S4 or C5 A6. It will require a new self cancelling ring ($400+ from dealer)....for starters.

Do a search in audiworld. Good luck!
Please correct me if I'm wrong, but if you read his post again, I don't think he wants to add the actual steering wheel, just the control module and the telephone button(s) (i.e., relocate the buttons somewhere else). This is an interesting idea Brian, and one I am definitely also interested in. Let me know if you find anything out.

This is an idea that I have also been toying with.

I have a spare A6 wheel with the MF controls on it. It's from a new shape A6 MMI I think, but the controls could be integrated into the console if I can work out how to wire in a control module.

Looking at the ELSA win diagrams, it looks pretty involved.

The MF steering wheel is connected via single wire LIN bus to the control unit which is itself connected to the comfort and power train CAN. In theory someone should be able to take the buttons off the wheel and connect it via LIN to the control unit. Don't know what your ECU will think once it sees the new steering wheel cntrol unit though.

okay working on getting some wiring diagrams together if anybody has it should be just a few pages listed under wiring diagrams "mutlifunction wheel".

also trying to source a wheel and clairparts is shipping the control module (should get by this weekend).

Craig - do you want to part with the wheel or can you source another maybe just take out the buttons/wires/controller and ship those?

exactly what i saw so far - meaning 1 LINbus wire directly to control module and then control module connected to CAN, power and ground - not sure on what ecu will think but should be okay as not connected directly to any other systems except via CAN - i hope at worst is just some errors on MF wheel module itself due to missing connections.

one way to find out is to just do it...besides if this works lots of peeps can just get module and junked steering wheel and have voice control and i guess aditional radio controls for much less then before.

from Lee - thanks again

No problem Brian. The wiring is simple, there is only one wire that connects from your steering wheel buttons to the control unit. The control unit then has two other connections for CAN H and CAN L.

On the control unit:
Pin 1 = CAN L
Pin 3 = CAN H
Pin 18 = Data from steering wheel buttons.

The wiring diagram is attached. You'll see there are also connections for ground, diagnostic (K line), Tiptronic controls (which you won't need to connect), 15 (accessory power), 30 (constant power), cluster illumination (to light up your buttons at night), and heated seat info (for heated steering wheels). I'd think you just need to hook up your data lines and power lines and you'd be all set.

How much did Clairparts charge you for the control module? This is something I would love to also do, if you can get it working. Thanks for working on this.
