  • Audi urs6 instrument lights fault aux

    Hello

    I recently pulled out my instrument cluster as I had lost almost all my bulbs. So i have replaced all the bulbs with good quality ones and it looks brilliant except no aux gauges still. I have never seen the auxiliary gauges illuminated so I pulled the cluster out again checked all the bulbs all OK checked the cluster for continuity with my multimeter and all OK. Can anyone shed any light on the problem.

    cheers Mat

    From a previous post of mine on qW:

    "Based on Bentley X62 for UrS4 and page W90-25

    Colour...Function

    Black.....Analogue Clock Adjustment
    Brown....(+) Terminal 30 - to instrument cluster dimmer switch
    Red.......(+) to Voltage stabilizer J166
    Orange...(+) to Voltage stabilizer and then cluster bulbs
    Yellow....(-) Ground
    Green....(+) Power to Oil Temp and Pressure Gauges

    But please take the above with a large grain of salt, and check for yourself."

      Yes the above tallies up with my audi manual and I have cross referenced the 6 pin plug to the main 26 pin plug and have continuity on all pins except the 2nd pin (positive terminal 30.) I Carn't find anything to tell me more about this terminal 30 an idea.

        I guess you are not familiar with Audi electrical nomenclature. 30 = constant (not switched) power = 12V power to the clock.
