2008 GL 450. WE'VE HAD ISSUES W/ SUSPENSION.
STARTED 2 YEARS AGO. DEALER REPLACED SHOCKS IN BACK. LAST YEAR, I REPLACED STRUTS IN FRONT. MALFUNCTION LIGHT CONTINUES TO GO ON AND OFF..MAINLY STAYS ON. THE CAR ALWAYS SEEMS TO BOUNCE OVER ROAD. MAYBE COMPRESSOR RESERVOIR HAS CRACK ?? PISTON RING WORN OUT ?? I HAVE A MECHANIC THAT HAS DONE WORK ON BOTH MY CARS. I THINK I TRUST HIM. MIGHT BE TIME TO GO BACK TO THE DEALER AND CHECK SYSTEM WITH ON BOARD DIAGNOSTIC TESTER. ANY OTHER HELP ?>?>?

you need someone with a star diagnostic tool to check system for errors
there is also an air block that can leak causing compressor to run a lot and overheat
you need to check for leaks with soapy water and stop them if any

ok guys here we go.. i opened the wheel well last night on my 2008 gl450. to expose the air compressor. when i started the truck the compressor kicked in. i decided to press the button inside that raises the truck. as its blinking and to raise..nothing happens. compressor still on...i squeezed the hose from compressor and its not putting any air out.. and a minute later the display showed compressor cooling down. arnott told me you shouldnt be able to sqeeze it if its on. it should be hard as a rock...sounds like compressor.. i also drove to a benz dealer to ask about replacing the relay..nothing wrong with the relay. the truck is at its lowest right now. doesnt raise at all. i am getting diagnostic test next thursday..$150 prob worth it. im told they replace old parts with new ones during the test to check off which parts are good/bad. wish me luck
