Q: i heard only a audi dealer can check it is there another way cause they are so damn expensive?
A: If it's an Automatic trans, there's a dipstick. If it's Stick shift, there are two plugs on the side of the transmission, the top one is for checking fluid level. Unless you like to get real dirty crawling around under the car, take it to an oil change place. They can check it easily, and may not even charge you if it is not in need of fluid.
