That method of opening the ISV a real "no-no" and is strongly warned 
against by Audi: never use something like a screwdriver to open (or 
to hold open) the ISV valve. The edge of that valve is rather fragile 
and easily can be damaged (causing the ISV to jam or work 
erratically); instead use something relatively soft, like a wooden 
pencil, popsicle stick, etc.
