Repairing window switch LEDs/replacing console switch bulbs

[schulz@tif623.ed.ray.com (Peter Schulz)]

The days are getting shorter, the nights longer, and I would like to see my instruments and switches!

First of all, unlike some other unfortunate Audi owners, my power window switches do still work.  What isn't working is the illumination.  I will assume that the illumination is provided by an LED, based upon my examination of a switch from another model.

Based on the experinces of fellow listers, what happened?  The switch that I looked at had an LED soldered to a resistor and directly to one of the switch leads.  

I thought that the advantage of using an LED over a bulb was its long life?

Did Audi not properly derate the LED, and put it into a near overstress condition?

Does anyone have a recommended replacement LED part number/source?


Also, the light bulbs in my ABS on/off switch and rear window defroster burned out.  The bulbs appear to be "grain of wheat" bulbs.  Does anyone have a part number handy?


Thanks and sorry for all the questions!
