Default Mini VAG505 Failed to Connect

i have a 2011 Audi A8L and purchased a mini VAG505 so i could access hidden menu and make some changes. However, just about any function I choose on the device it states Failed to connect. My check engine light is on and I know why gas cap loose. Tried to clear code nothing. Used my cheap Bluetooth diagnostic device and it cleared it easily. So now I have a device that is supposed to be much more sofisticated and canít even connect. Frustrating to say the least.
Also, just changed my front brakes yesterday myself and the Brake light is still on. Does it need to be reset or is it supposed to automatically go off? I used OEM pads with the sensor cable attached.

What is a mini VAG505? I have a VCDS from Ross Tech ($200) and it does everything like the factory tool.
