Sorry to dig this up again but have done a bit of searching and can't seem to get a definitive answer.
I have managed to get my hands on a mfsw from a 2001 s3 which looks identical to the standard 4 spoke wheel on my 04 a4 apart obviously from the radio buttons (3 down each side of the air bag). Now my car has full dis and cruise so I'm fairly sure I have the correct steering wheel control module. My question is what else am I likely to need to change these over?
Cheers in advance guys!
