A4 B7 non MFSW Upgrade to 8U0124 MFSW from A3 / Q3?

[tommy5150]

Hey Guy's,

Upgrading non MFSW on my 2005 A4 B7 Avant to a 8U0124 MFSW from a A3 /Q3.

Was just wondering if anyone can confirm if the upgrade will work?

Parts I will also be changing to so MFSW works:
8U0124 MFSW from a A3 /Q3 (is it the 8V one?
Airbag for new steering wheel (still trying to work out which air bag goes in the new wheel)
Airbag Harness - 4F0971589A
Complete steering wheel stalk cruise control, Slip ring, steering control module - 8E0953549Q, 62471980A, 62479150I

Seen this post HERE but they don't say what model number they use to make everything work. Vid HERE

Wanted the A3 wheel as its a bit smaller and looks better I think.

Then all the coding so it works. I believe that's everything. Am I missing something?

I've included picks of everything.

Please let me know if anyone has any info on this. I did find a video where a guy installed the A3 MFSW into an A4 B6 which worked but did not say what he used

Or do I have to used a B8 MFSW with everything from the B8?

Any info would be much appreciated thanks heaps
