Wrong plugs, coil output too high, oil consumption, running rich, poor quality fuel, low compression. Any codes?

Welcome to Audi ownership, especially old, used Audis. People who buy these cars new don't take care of them. So you're now experiencing deferred maintenance, and that will likely go on. I suggest you take the car to an Audi mechanic and have him go over the car, something you should have done prior to purchase, so he can find all the things you're going to have to do to make this car as reliable as an old Audi can get.
