• not familiar with TDI but see if it physically broke a cable or linkage???

• 2001 is drive by wire, no cable. Read the code from the ob2. You did not say if it idles??

  Yeah sorry that's my bad.  I am just super confused and the vehicle is not in front of me so I am in even more trouble.
  The car idles fine but physically pushing down the throttle doesn't make the rpm increase what so ever.  I am stumped

  The car is trying to tell you what's wrong... go to Autozone, Napa, etc and have them read the code(s)... it will tell you exactly what's going on.
  
  Anything else at this point is random guessing.

• I'll take a stab at it, and say the MAF went to hell on it. Try unplugging it and see what happens.

• Throttle Potentiometer.  Just happened last week on my neighbor's Mk4.
