WOT Switch Adjustment

[Apowell@ezlink.com]

With thanks to those who steered me toward the WOT switch for 
lack of boost on my 200, I found that there is one more operation to 
be carried out after installation - adjustment.

The throttle switch housing contains TWO switches - one idle 
switch, one WOT switch.  Adjustment is in Bentley sections 25.24 
through 25.26.  Essentially, they want you to be sure there is 12V 
on harness connector pin 2 (the middle one) with the key on, then 
adjust the idle switch so it is on with a shim of .004 inches 
between the throttle stop and the moving part of the linkage.  Final 
step is to confirm that the WOT switch is on when the pedal is to 
da metal.

Requires only a volt-ohm meter.  Probably one of the easier 
procedures I've found.

One caveat: getting at the bottom mounting bolt for the switch 
housing is NOT recommended when the engine is hot.  But 
working from the forward side with the correct open end wrench, it 
can be loosened and tightened without removing anything else.

To replace the switch, I pulled the metal turbo tube loose at the 
bottom end -generated enough slack to pull the switch off toward 
the passenger side.

Another arcane Audi lesson learned.
