Heated Steering Wheel not working on Audi A6 Quattro?

 

Would it be possible for you to take a cooking thermometer and measure the temperature of the surface of the seats and/or steering wheel, and then compare it to another model at the dealership? I have one for the meat temperatures that would work perfectly--maybe you have one or somebody you know does.

By doing so, you eliminate the question of whether or not it is your perception or a service issue.
