First, I would recommend some punctuation to make your posts easier for people to read.
Second, a few years ago I bought an S600 TT that of course came with ABC. After 160,000 miles, apparently its accumulators were weak, as it sounds like yours are now. As I was driving it home after purchase, the rear accumulator exploded. When that happens, the car slams down like a low-rider and you're calling a tow truck. Fortunately, I was able to drive the car to a shop using the ol' trick with short sections of 2x4's above the upper control arms, combined with some very gentle driving.
That's the risk of ABC. Its failure mode is, "you ain't drivin' no more."
Yes, I converted to coil-overs (Strutmasters) + anti-sway bar right away, and I haven't looked back since.
