All of the threads on here about airmatic and ABC problems got me thinking - is there any special maintenance required to help prolong the life of the airmatic system? And if so, will that maintenance be included in normal 'B' services? I'm thinking of jobs like checking hoses for wear, replacing fluids (are there any? probably not on airmatic) and changing the compressor intake filter. I'd hate to think I was missing out on some simple maintenance that could reduce the risk of expensive future failures. Thanks in advance for any advice from those in the know!
