Hi mates
is there a chance that i can still repair rear right side air suspension? Lately I can hear pump working when I do morning start of the car.

 

Is one side sitting lower than the other in the morning? You probably have a slow leak in the system somewhere, your airbags look original - it could be one of the bags has a slow leak and is on its way out. They are pretty simple to replace. In my case - I had a air bag blow out on the highway - lost all the air in a matter of seconds, and the compressor wasn't able to keep the system pressurized, so I drove home on a flat suspension.
