Disco 3 Air Suspension

Hi, I am a new Land Rover owner, and have just taken delivery of a Discovery 3 TDV6 S. What a fabulous bi8t of kit this is......except......I have a recurring Suspension Fault problem. I have had the car for four weeks, it has now been back to the dealer three times, and I have been told today that it needs a new compressor.....anyone out there had or got a similar problem? Incredibly frustrating; keeps vehicle at Normal Height, doesn't allow for adjustment, but after switch off - switch on, can be absoultely fine for 50 miles...or 5 miles; no pattern. Any other experiences? - and if so, how did your dealer sort it?
