I replaced the throttle position sensor on my S8 and made a massive difference to the drive.
A problem on the slightly higher mileage cars is that an engine breather chucks oil through the throttle body and gums it up.
I removed the throttle body (Quite straightforward without removing the inlet) and stripped it and cleaned it. I also relocated the engine breather pipe to stop it being gummed up in the future.
Car drove miles better afterwards.
