My audi has a different type steering wheel then that showen on there web pages.
I have three buttons (up and down) on both sides. Audi shows two buttons on each side with a MOD button next to them.

This is not a good site for that type of question. Most of us, here, don't drive high-end cars. Instead, we tend to drive older Honda, Toyota, Ford, GM, and Chrysler products.

Like many "high end" cars, Audi has various configuration options available.
Each one has it's own features and it's own failures.

If the vehicle you are looking at doesn't have all the same bells and whistles as another similar vehicle, you may just be lucky: The more "gimmicks" a system has, the more likely there will be a failure at some point.
And, quite frankly, the more "gimmicky" the failure, the more costly the repair.
