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.

Sounds like your pump is fried.

Yeah, you probably should have purchased an Infinity or maybe you should look at the shock and spring conversion kits so you won't have to replace the air components again. With that said, the air.compressor should be less.expensive than the conversion to a standard suspension.

thx for response...instead of going to the dealer, i have a local guy i think i can trust. he installed the front struts for a very fair price. much less that dealer price. i'll feel better after the diag test results next week...i'll keep everyone posted.

When an air strut fails, make sure to get the replacement from Arnott. Lifetime warranty and very good returns procedure. They pay for shipping and the return of the old unit. Great company.

I would recommend replacing the valve manifold at the same time as the compressor. It is know to fail as well.
