one of the most common failures of the Audi (44 series, 100, 200, 5000 
series) is the loss of the nitrogen charge in the accumulator. I have 
successfully installed a schraeder valve and restored them wiht a 
nitrogen charge, though you need to recharge every year or so. (I 
personally just leave mine off, if I can't drive around it with a high 
horsepower, all wheel drive car, then so be it...)
