Question about 2002 Audi TT
Sounds to me like you have two common failures on your car. One is the fuel sending unit in the tank (on the A4, which uses a similar design, this is a known issue, causing wrong or erratic readings on the gauge). The temp gauge is a failure of the coolant temperature sensor, another known issue with Audi. Both sensors can be bought through a dealer of course, but they're going to be ridiculously expensive. On my A4, I usually buy from www.germanautoparts.com or www.ecstuning.com - both have a lot of parts and knowledge, and their prices are very good.
