Dynamic seat side bolster/bladder deflates

Recently I bought my MB E350 Coupe and I noticed that driver and passenger bolsters are not working properly. As you start car pump is pumping air into the seat then it deflates right away. I read that other MB older versions had this issue. I have purchased 2 units A 000 910 3175 and would like to replace them. If somebody can share how to do it it will be great. Seat also indicates that it has Airbag what precautions should I take not to trigger airbag. On a diagram that part is # 420. Thank you

Do you have by any chance install instructions for Dynamic Seat Vacuum Pump and Reservoir replacement ?
Also, do you know if two front seats have two independent pumps or one pump is for two seats?
Appreciate your help !
