Shortened shift linkage and widened throttle, part deux



Hello, virtual club!

I couldn't recognise my own post, when I received it back from the list.
That ASCII art of mine was really screwed up big time, although it was perfect on 
my screen. I have redrawn it and moved all the way to the left margin. Here it is:
                        
        O<- ARC ->/

The throttle:

Remove the throtstle body as an assy. Three allen (5mm-?) bolts there. Make sure 
you get a new green paper gasket beforehand.

BTW, now would be a good time to clean it up of accumulated gunk. I use the brake 
parts cleaner. Please work in the open air! The stuff is ether based and is HIGHLY 
volatile and flamable. I guarantee a headache in 10 min of working indoors.

On the inside of the throttle disk itself, in the lower half of it, you'll find a 
restrictor. It's a metal segment, shaped like a wedge, same dia. as the throttle 
disk, about 10mm thick in its lowest part, and is attached to the throttle disk 
with two 4mm screws. Remove the restrictor, cover the screw holes in the disk with 
the same screws (you will have to find two 4mm nuts in order to do this) and enjoy 
a quicker pedal responce.

I have no idea why Audi added this restrictor the first place. When you open up 
the throttle this restrictor keeps the calibrated gap between the throttle and the 
inner bore very narrow for quite some time, and only when the restrictor clears up 
the "floor" of the bore, the gap starts to really open up.

Without the restrictor the gap openes immediately after you apply your foot to the 
right pedal. I've had it done several months ago now and really do like the 
difference it made.
