Question about Audi A4
Never heard of such switches.
A likely cause to the problem IMHO is that the incident made the engine shake so much on its mounts that a cable or hose loosened in the engine.
I'd begin checking vacuum hoses, air intake hose after the air mass meter unit if you have one, ignition cables if applicable, sensor contacts and other cables to see that you have no loose ends, no cracked hoses and that everything looks ok.
Squeeze all hoses and hose connections you can find gently, pull a little on all cables and contacts and I think you will find what is wrong.
I doubt something serious could have happened here that can't be fixed with some duct tape in the "worst" scenario... :)
Good luck and don't worry!
