I am currently attempting to fit the new style flat bottom steering wheel with multi function control to my 2003 8L s3.


so far i understand this is possible by attaching a a4 scsm part no: 8E0 953 549 R to the LIN bus parts of the A4 steering module, the CAN bus section and then tie these parts into the A3 CAN bus system and steering module.

would anyone know where i could find the a4 wiring schematics so i can figure out how to connect up the a4 steering coloumn electrics?
Any help or pointers will be very much appreciated.

Hi
I fit the steering wheel audi s3 8p to S3 8l 2002. I bought a multifunktion module (4B0 907 487F) after etka, and I do not know where it is set up correctly. Where it should be plug in?Does this have any chance to work? Please help

yes this is possible as it is fitted and fully working in my 8L s3, it works perfectly with the rns-e and audi bluetooth module i have also retro- fitted. one major problem was the new steering wheel airbag is dual stage and the 8L operates on a single stage ignition. This i had to overcome by rewiring but i some times get a fault code for the steering wheel airbag of "low resistance". Apart from this everything else works perfectly.

Which module you used? I plugged the module from Audi A6 and Audi A3 8l (etka info), but it does not work correctly. Only the buttons are backlit as this module needs old steering wheel with a small built-in module in the steering wheel. Please tell me which module to connect and can you give me a pinout or scheme. thx

The CAN bus connections must be made to the Convenience CAN , definitely NOT to the Powertrain CAN.

Don't know about the other 3 wires - colours don't mean a lot because they can change from model year to model year, what pins are they connected to?

I think that I connected all correctly.
buttons illuminates when I turn the light on. Also operates the dimming and brightening, but the buttons control does not work. Coded the rns-e for MFSW "5" on the end.
It seems to me that the module needs to be coded. But why?:-k I bought used one for exactly same steering wheel so should be coded. How can I do it? There is no k-line. Cant do it in my car](*,)

and L-bus, 12 volts to steering wheel (front side of module)
and 12 volt to igniton socket

I don't understand where I must connect this cable on the module...please can you explain the connections through a photo???
Thank you!
