You have more of a project than you might think. And a pissed spouse too? You really need to go through the entire fuel system before trying to start the car. Bad gas, will potentially clog injectors and other critical components. Since the car was in the elements, its safe to assume that the t-belt is shot. If the belt slips, add another $5K to your project for head work to replace bent valves.

Suggest you take the car home, replace the t-belt and components, ignition cap and rotors, spark plugs and possibly wires, flush the entire fuel system, replace oil........then try to start the car. I am sure that the belt tensioner seals have gone bad and there could be a fair amount of slack in the belt. If you manage to get it started and the engine is miss-firing for any number of reason, this will raise the probability of the t-belt slipping and bending valves.

Personally, I would pass on this project. Buy it and part it out. The work above is going to cost $2k or more if you do the work yourself. And then the interior needs sorting. Rusted and moldy you say? That could cost thousands to sort. What's a decent early S4 cost? Less than what this one will cost the get back to a number 3 car.
