Question about 1996 Audi A6
This is the 30v engine (the valve cover dress-up panels should say "5V" on them, for five valves per cylinder). On this engine, the thermostat is buried in the front of the engine, and requires serious disassembly to reach. The front of the car must be swung open into what is called the "service position" to allow easy access to the front of the engine, and then the fan, accessory belt and tensioner, and timing covers have to be removed. Access to the thermostat is partially blocked by the timing belt tensioner, so that will likely have to come off too. If you're going to change it all, you might as well put on new parts and get your timing belt service out of the way. You can buy complete kits for the timing belt service online at a variety of supply shops for about $250. It seems ridiculous to do this much work to change a $14 part, but unfortunately that's the reality of this engine.
