1998 Audi A3 Sport throttle body earth strap
 

Hi all, I have just noticed that the earth ground strap from the throttle body of my car is only attached at the throttle body end? I had some work done on the car so maybe the guy forgot to put it back on, question is were does the other end bolt on to?

If anyone could help I would be grateful.
