L322 new dunlop airbags front noise

Bought my car 2 months ago, Car had orig. airbags. 100000 miles. Was some noise from shocks front .not much. Got a complete set new airbags with car. Dunlop. Changed both front. Now it is terrible noise when i drive over small holes in road and "speed stops". Last owner both them in England. What is wrong? Are shocks empt ? No oil/gas? Have to put old ones back. No dtc,new compressor. All eas ok.

Dunlops are known to make odd noises on fitment, ask @holidaychicken he has experienced this....

Will do. Have sent mails to dunlop and uk seller.
