[s-cars] A6 tailight

[Tony Curran]

Dennis,

If the circuit board is cracked then the electrical traces that are on the
surface of the board may be broken - no continuity. A way to fix that would
be to solder a wire across the crack thus completing the circuit. But this
may only be a band aid approach as something is causing overheating. It
would be surprising if a 1156/1157 type bulb generated enough heat to melt
anything. Though if it is tightly packed or touching the surface it may.

The concept behind the LED bulb is good but one would have to repair the
circuit board first.

Good luck

Our 05 A6 3.2 has been giving me fits for over a year now. The right rear
tail light beeps a warning and ceases to function, leaving no right brake
light or right side signal lights at all.
When this started over a year ago, I noticed all the bulbs were fine, and it
would only occur after running about 10 minutes or when the rear of the car
was in direct sun for awhile. Looking at the assembly I noticed a portion of
the plastic housing around one bulb and next to the circuit board looked
heat damaged and was cracked. I put some aluminum reflective tape over the
crack but it didn't seem to make any difference. I next bought an LED bulb
thinking it might burn cooler, but again no joy.
I then bit the bullet and bought a replacement from Chris Chambers, and when
it arrived it showed the same plastic melting and cracking as my original.
Very disappointed, I installed it anyway, and to my surprise it worked for
awhile, but alas it has now also stopped working.
I seem to remember hearing that someone was able to re-solder the little
circuit board or replace a component and achieve a successful repair. I can
see no way to access the board without destructively removing it leaving the
entire unit inop. 
Anyone with info or procedure to affect a cure short of buying a new (read
very expensive) replacement?
TIA
