Noise suspension after installing bilstein b4

Hello everyone,

I'm desperate, after installing all 4 shocks bilstein b4 a noise comes when passing from certain holes, déformations....little knock from all 4 shocks! Everything is new arms, shocks, adaptation(module 14) is done! Sometimes the shocks sims loose! Every bolt is ok Everything sims ok, but that noise... skoda superb 2017 2.0 tsi L&K 280cv 4x4! H&R installed! With oem shocks Everything is ok......
