instrument cluster repair

[ksternal at cox.net]

I too have been through Audi IC Blues - (not just my '91 Avant).  I solved most with a replacement that works. The one problem not directly the fault of the IC which has been eluding me for the four + years / 70k miles since buying the car from the original owner was the CRUISE CONTROL.  Bentleys shows a  White/Blue wire that goes from the Cruise Control Module to the radio and  the IC.  It also is the "signal" for the Differential Lockout to disengage after 15-25 mph (have never even tried it till now...this is a San Diego car...and I don't take it out on the beach!).  This SOB was installed in the wrong place at the radio (original replaced by owner 1, re-installed by me after getting it fixed ---HEY this is a CLASSIC,,, and there was nothing too lacking in the original Blauplunk).  Just cutting the wire MADE THE CRUISE CONTROL WORK! Two other points related to this and maybe of assistance to other owners: 1) the Violet, Yellow and Green wires were cut during the radio replacement (and most likely with any non- OEM radio replacement) that give the IC the sound system read-out (i.e. mode, station).  Re-wiring those (after finding block pins from an VOW to put into the aftermarket plug installed  w/o the pins (locations T 10 1,2 3) fixed this problem (which intestinally is also a problem on my '97 A6 purchased with 38K miles).  2) re-lamping the IC while you have it out is a no-brainer, and this my second time the up-graded brighter bulbs (kind-of bright pink) have been a nice encounter, which I recommend.  Still not understanding why cutting the white/blue wire going to the wrong pin works....as opposed to placing it where it supposed to be (T8 e-1) (which I have not tried) but I'm not going to mess with results --- IT WORKS!
