does the picture on the message board with a thermometer in water mean thermostat problems?

It has something to do with the cooling system, may be low on coolant. Check that first. Whatever you do, don't let the engine overheat, it will cause some expensive damage!
I would get this looked at by a good Audi shop, have them diagnose it and if you want to fix it yourself, then do it, but let a professional diagnose it for you.
