Suspension Noise problems of the 2006 Volkswagen Passat

When driving my new 06 Passat 2. 0t at 35 mph+, w/ passengers (avg. Weights - approx 140 ea. ) the car bottoms out, rubbing the road surface, over even moderate bumps & 'swooping' humps in the road. It occurs w/ more severity when encountering bumps during cornering. It started without warning, and was 'moderate' at first, then began to get worse as time went on. I can also hear a 'clicking' sound when the driver window is down, & going over even small, slow speed bumps (<5mph) after several of incidences I took it the local vw dealer in vancouver, wa,. After 3+ visits, no solution. They told me it was fine, they couldn't reproduce either the clicking or bottoming out. I contacted vw USA & filed a complaint with that dick hannah dealership. I was quickly contacted by the service manager who offered to take a ride w/ me, during which we easily reproduced both concerns, at slow speeds, within minutes of leaving there lot - she was shocked, & said she'd look into it - which she did. The solution? "the factory installed front mud flaps were 'too long' & draggied when encountering bumps" ! needless to say, & even w/o being a 'mechanic', this answer was obviously not the reason for a suspension that 'clicks' loudly over bumps & bottoms out during normal driving. I accepted this answer w/ the idea I'd do some additional research. The car continues to bottom out, is getting worse & ironically only happens on the drivers side - regardless of whether I am driving (at 180lbs) or my fiance' is driving (at 115lbs) now even w/o passengers! there's definitely an issue w/ at least the front strut unit - which would also explain the clicking coming from that unit. Although I have brought it back to the service manager, they stand by there diagnosis - that nothing is wrong with the car. I'm very disappointed in both there service and level of expertise/knowledge - every suspension mechanic I have spoken with says that it sounds like a faulty or leaking strut unit - an easy fix.

: the contact stated that while driving at low speeds of 0-5mph the engine jumps to rpm's of 900 to 1000 rpm's causing the vehicle to lunge forward. This occurs more often when the vehicle has been running for a while and the engine is hot. The rpm's go down only when the engine is placed in neutral and the motor is revved up, or when the vehicle shifts into second gear. The vehicle idles roughly and hesitates. While stopped at a light or stop sign, there is lag between when the accelerator is depressed and the when the engine kicks into gear. When this occurs, the vehicle lunges forward. The dealership cannot duplicate the problem. While parked, at low speeds, or turning the vehicle right or left, there is a grinding sound coming from the right suspension area. The dealership replaced the right front passenger strut bearing which seemed to help for a while, but now the grinding sound is back. The grinding sound is now coming from the left suspension area.
