Are all e83 steering wheels interchangeable?
 

Want to replace my standard 04 2.5i stock wheel with with a 3.0 multi function or sport steering wheel?

Guessing there will be some some programming involved?

Yes, they are fully interchangeable.

Sweet now its the search starts for a sport wheel to replace my stock one

eBay! They are easily found there. I removed my standard 2007 wheel and retro fitted a heated steering wheel, very easy job!
