Hmm, not much info to go on. What do you mean by "air seals". And you say car can be driven but is "rough". What do you mean by this. What fault message have you got on the dash ? If you have a fault message, have you had the fault codes read. You say the driver's side air spring has been replaced. What has it been replaced with ? Originals were Bilstein, and these are available as OEM on the aftermarket.

Mileage is not huge. Many of these cars get to 200,000 and more. However the air compressor for the air suspension would probably need repair or replacing by now. Do you know what work has been done on the suspension ? The bushes in the suspension are not long lived nor are the air spring lower bushes. How long have you had the car ?
