I have a boost gauge but i haven't seen a difference. Im the
third owner. The first owner was in range rover club but sold the
car cuz he was spending more $ on the audi than the rover. The second held on to for the last couple years im call him and see if he knows anything about it. Is any body in the santa fe area or close by that has vag.com.

 

I have a feeling this button will lead to good things...

 

Definately figure out why the CEL is flashing.. what code, etc. And, QUIT PRESSING IT! For all you know it chages the cam timing or something equally destructive!
