Accumulators, Rear Suspension, the whole nine yard

[pilot2000]

I hope I can find someone that can help me here, b/c I really don’t feel like spending $2885+ on this.

My 99 S500 road a bit rough and bouncy, I replaced the Accumulators
Still rides rough for an S500, took it to the dealer to diagnose they said I need new Accumulators, even though I had just replaced them 2 weeks ago, and new shocks at $800 each.

Now when I did the Accums I lifted the car on a lifts but not on ramps so there was no pressure what-so-ever on the suspension, I bleeded the system, took the old accums out and fitted the new ones. The system did not drain any fluid, even though the reservoir had lot enough in it. After replacing the accumes the car is a slightly higher then before, more like normal height now, but still rides rough.

Q1 is what did I do wrong?
Q2 is How can I properly bleed the system to make sure I get all the air out?
Q3 is Can the Accumes go bad that fast?

HELP!

Thank You very much in advance
