Having trouble with this system; airmatic malfunction warning followed by rear suspension raising to full extend and staying there. Dealer replaced airmatic compressor and valves. Now there is a thump and sometimes a flutter coming from engine area when starting out and compressor starts. Dealer replaced airmatic suspension relay that is believed to be faulty. Thumps and flutter still occur and plan to return vehicle again for repair. Any ideas on what this is or has this happened to anyone else?
