Re: quattro-digest V3 #1091



Procedure depends on manufacturing date of car; I think easy way to check 
is the exhaust manifold - earlier cars were stainless steel, later ones cast
iron 

A) Up to March 1990:  
    1) under driver's side glove/map compartment (near steering column) you 
        should find two diagnostic connectors, with two jacks on each one.
 Bridge/
        short the lower jack between each connector.  
     2) start car, turn off all accessories, make sure car is warm but
 radiator fan
         is not running, check idle speed. Should be 800 RPM +/- 50
     3) adjust idle speed to spec at adjusting screw on throttle body (accel.
cable
         is sticking out of it, adj. screw is pointing approx.to the air
cleaner).

B) From March 1990:
      1) Place spare fuse into top of fuel pump relay
       2) Follow (2) and (3) above,but idle spec is 800 +/-25 RPM

Good luck!

 HI!
 
 Would you mind telling me what that procedure is, or is it too involved to
email or fax?  
 
 Just wondering if I can do it myself, since I have lost all faith with the
dealers around me...
 
 
 Thanks.
 
 Saam.
