I highly doubt it. The stock resistor dissipates horrendous power. It is 
nothing but a pair of dumb ballast resistors , 0.2 ohm and 0.7ohm in series.
I wonder why Audi chose such a crude approach instead of using, say, 
thyristors. 

When it happened to my 5000, I just drilled the rivets out and  separated 
the angles that comprise the body. Inside there is a sandwich of Mica, NiCr 
resistor, shaped like a comb and one more layer of Mica. One strip of that 
"comb" is usualy broken. The repair is easy, just cut a square metal  patch 
approx 10mm x 10mm (I used pure Ni because it is solderable, although Cu or 
brass would probably do just fine). You will need to braze the patch to the 
brake in the "comb" with some silver solder. In my lab I have a tiny 
"juvellers" torch used for fabrication of the custom scientific apparatus, 
it makes brazing a snap. Rivet the repaired sandwich back together and 
voila! you just saved youself $115. The repaired resistor still workes on my 
old 5000s (4 years later).
