Problem with shaking car
I have a problem with my car...
Its lowered with links.
And in the lowest mode the car is shaking when i accelerate and brake...
If i put the car in "lift" about everything is gone...
What can this be?
I have Air Suspension Sport on the car.

On the guess side and w/ very little info to go on, my first and usual instinct for a D3 would be upper control arm bushings. A "when" not an "if" for all D3's.

Ok.
Then the guess is upper control arms/bushings?
It started for about 6 months ago...
I have driven the car for 2 years now without any problems, so maybe its time now...

Sorry can't help but respond to the title in the post, makes me think of Shaken Car Syndrome, which makes me also think of the following:
I know this is not a helpful reply, but I sure thought it was funny.

I did check the documents, all 4 upper control arms in the front was changed before i got the car from the shop.
Can they be worn out already?

They could be worn out already yes, would depend upon a few things and the lowering links could accelerate the wear. Would be good to know the parts (control arms) that were used, Lemforders, Original Audi parts or lesser knockoff replacement parts. Would also be dependent on how the CA's were installed, meaning was everything torqued to spec with weight on the suspension vs in the air with the suspension hanging. A visual inspection of the control arm bushings should tell you if they are worn. Lot's of control arm articles posted on this forum, search and you should find all the information you need.

Control arms won't fix your vibration, check your ca by remove the CA from the pinch bolt and test. I used to have vibrations, replaced all CA and nothing changed until I got new tires, new wheel inserts and high speed balancing, then the vibration was gone. Btw, I didn't have vibration when accelerating only high speed braking.
I would bet the 2 c-links sway bar are shot.
