2007 Cayman XL 36 ft loss of air….

[UK_Steve]

Hi all, just taken out Cayman out of winter storage and have two problems, the first being the rapid time in which she loses air from the suspension and air tanks.

From full tanks to air bags flat at the rear and almost flat at the front in approximately 30 to 36 hours, I don’t recall last year it going down that fast, does that sound about right or do I need to go looking for a leak?

When the air bags are flat the tanks (both) then happily hold at around 50 to 60 PSI without losing more air.

Many thanks in advance for any help anyone can offer.

Kind regards
Steve

Yes Steve, it seems that something has happened. You need to charge the air system up and shut it down and go under(jacks down)and listen for leaks, a spray bottle with soap in it will aid you in finding the leak. Look at the dump valves (solenoids)
for the air ride leveling system. If it is quite where you are at you might be able to hear the leak.

Hiya palehorse89,

I feared that may be the answer, have two things I now need to do (this and replace the alternator), next weekend is busy the weekend after is now a coach weekend.



Where she is in storage it can be very quite, so I may be able to hear it, more than likely will find it with soap spray, I guess the backend is the best place to start as the back end goes down fastest.

Many thanks for confirming what I suspected.

Cheers
