Car got really bumpy...
So i just came from trip to San Antonio, and my car got really bumpy on the road, like if there is small bump on the road it feels that i am driving somewhere offroad, so went shop to do diagnostics and they didnt find anything wrong with, so guys i need ur opinion what could be wrong, and what parts of the suspension responsible for the comfort/softness of the ride?

The Airshocks are directly responsible... are yours originals? I notice this sometimes in my car when it hasnt been driven in a few days so i tell the airmatic to raise and then lower back down to normal to make sure everythings at the right level... seems to help

I tried before but it didnt help, front left shock replaced about 9 months ago, right one about 14 months ago, left one is bilstein right is oem.
I mean it should be bumpy because my car is dropped, but it just feels like someone is sitting under my car with a big hammer and hit my shocks on every bump.
Is ur car dropped?

Three alternatives that come to mind are: 1) Your ride control switch is in Sport 2 (2 red lights illuminated); or 2) You have lost pressure and your struts have gone into the "safe" mode (to keep from bottoming out) - this is usually accompanied by dashboard warnings and stiff steering, plus the car will be noticeably low; and 3) your airmatic relay is failing in the "on" position and overpressurizing your system. One would expect to hear pressure releases periodically, if the last event is occurring. If it is, the failure will soon burn out your airmatic pump.

2)- No
3)- Yes, i do have pressure releases periodically.
So what should i do now, i replaced suspension compressor couple of weeks ago and they replaced relay also, sorry for my english but "airmatic pump" and "airmatic suspension compressor" is the same thing? if yes what should i do then?

They are the same thing, and I would take it back to the shop that did the work, and tell them that this problem occurred after they did their work - they should fix it.
