You are right, the higher the temp the more baking soda buildup and crud, the more buildup the more heat etc etc. I would think it is probably time to flush. If you do think your thermostat is bad johns advice was right. You can also soak it in white vinegar overnight to clean it. There are posts down stream from yours about engine flushing. Check them out. Heat is a killer on the A-4. Your engine should be flushed about every 3 years.
