Allroad 3.0 TDI air suspension - what else should I possibly replace ! (At end of my tether)

[Upanddownv6]

Car in next week for repairs. A previous bag had burst (hole) out of the side and another had leaked from the seal.

I have now decided to go down another route, as I have replaced multiple rear airbags, had lines checked for leaks, sensors etc checked for faults etc. Now the garage can find no leaks but the spring is going down. It makes no sense.

Now I have come to the conclusion to replace the rear strut shock absorbers. My logic is that when shock absorbers reach end of life, normal steel springs take the strain, but with air springs they can only do this for a limited amount of time before they fail or leak themselves.

I have no other ideas before the car gets turned into street art. It is the most unreliable system I have had in any car I have owned or run, and I have had 100.
