Hi I'm a new member and am seeking some help with the dreaded air suspension. My 2004 cdi 270 elegance estate started dropping on the rear, drivers side whilst parked. It wouldn't do it all the time but once every 3 to 5 days. As soon as You started the engine the compressor would cut in and raise the car it wasn't low enough for a warning light on the dash but it was obviously noticeable. I took it to my Mercedes mechanic who put it on a machine to test and he said the air bag had a leak and would need replacing. Merc do a reconditioned option for £340 so I told him to order it. But before I could take the car back the other side started dropping and it was low enough to give the red warning notice car too low. Again once started the compressor would raise the car and it is fine to drive. I called my mechanic and told him the other side was now also going down he said it would be better to replace both bags. Now that would cost around £1000 including labour so I've decided not to have the work done and have gone and purchased a 2007 280 cdi sport estate. The funny thing is that in the last two weeks the 270 cdi has not dropped at all. Which has me scratching my head, surely if the airbag or bags had a leak it would always be dropping not occasionally ?? . Or is it just a sensor fault ??. I've used this merc mechanic over the last two years and never really had any cause to doubt him but this issue has me wondering. Can anyone out their confirm that a air bag leak can cause a intermittent fault.
