Thank you @newmoon, it helps to understand what is going on internally. I've isolated the problem to the suspension motion (bobbing up and down) and the interior air pressure.

I've seen a big drop in the sick feeling with the windows all cracked open. I have also switched on the internal circulation switch for the A/C. It helps for driving to work, but on the weekends the girlfriend likes the windows up, so I feel a little woozy after trips. It's lessening so I'm hopeful that I can get past it and enjoy my A4.

I'd consider the above before all other sources.

Thank you for the reply. Fun read (sarcasm). If you're right, I won't be worrying about it very long as I lose my hearing in the next few months.

"When the ear is attacked, the progression of damage and functional loss is rapid, occurring over weeks to months and usually progressing rapidly to the
second ear."

How interesting that my autoimmune disease has begun precisely on the day that I purchased the car. Any other cheery things I should look into?
