Eurocharged Canada is having issues diagnosing my rear suspension leak. They have had the car a week and are telling me it's not easy to figure the leaks out. Is there any direction I can give these guys on helping to narrow down the source of the leak or is it just a PITA to diagnose?

Hulk

If you are sure your pump and bags are good then it's a matter of narrowing down to the plastic air lines and valveblock, soapy water ,wait and see.

Hotsauce55

Not sure what they are doing then. They did replace some fittings from the compressor block but car sank again.

Hulk

If it keeps on dropping when car is off most likely the bags or reservoir. Better off changing the bags for arnotts that's have no reservoir.

What is star saying?

Hotsauce55

Not sure they are using STAR. I keep asking but no feedback really. What's testate do they need to run?

Hulk

When you run an airmatic test in star the first thing that gets checked is the pump and then from there it goes to every corner etc

tell them to put it in comfort mode ad see if it drops,, mine would drop a little in cold weather and selected sport II and it has been steady... my understanding sport setting eliminates the reservoir --

Hulk

sport mode stiffens the shocks(struts in the rear)

Hotsauce55

Is there 1 or 2 ŕeservoirs for the rear bags? Both sides fall at basically the same rate.

there are 2 ,,, one on each side - both dropping together to me would indicate a line or fitting has a slow leak -- good luck or bite the bullet and replace them will arnotts air coils or the strutmaster coilover kit

Hulk

Are they both dropping equally? Sometimes one side drops and the other side drops slightly because of that. If you go Arnott you should change both together anyway because they don't use a reservoir anymore.

Probably the rear air springs leaking. Mine had same issue. Bought arnotts and good to go. Now my fronts went out. But, I thought they would because they are 10 years old originals.

GL, let us know what it was.

Just drop ALL of the air and go coils. Problem solved

Hotsauce55

They found the line leaking from bag to reservoir. Would have went coils but with at least 1 member getting squeaking issues it was a no go for me.

When I park my E55 for 3 days, both rear just sit on the ground. This never happened before until last month. I am buying BC BR coil over now... Don't want to deal with the front air suspension in the future.

2 mins after driving away from EC Canada the check suspension warning came up lol. Arghhh! Right side of car seems to respond normally to height adjustment ie. Sport 2 vs comfort. Drivers side not so much.

Hulk

White warning or red?

i'm gonna keep airmatic till i die. factory airmatic has built in adjustable dampening with suspension setting. I love it!

Hotsauce55

the white... red probably to come lol

​​​​​​I agree and don't plan to buy another car without it.

Hulk

Do a star test and it will show you the problem

Hotsauce55

Yah gotta pull the trigger on a star system soon!

Did they check the rear level sensor? If it's not adjusted properly it won't ride level even if everything else is 100% right. Also I have found the system to be erratic. Sometimes it leaks sometimes not. Sometime it dips on different sides. I'm on a 6 month stretch of no leaking at all. Other times it's overnight. On mine going into sport then back to comfort put the leak in remission. It's not leaking enough to ever find it.

Hi! Have this error-message "arrow up, visit workshop" after a few minutes driving. Im not able to see if the car is lowered, like it was when my front struts or rear tanks were leaking, so i do think there is something else. When stopping the car i occationaly hear a air-leaking sound from my left front. Makes me think it might be a leak in the compressor. Does this seem right to you experts? And if it is a leak in the compressor, should i change it now, or wait till its competely dead?

Keep in mind that your rear bags are rubber, and over time the rubber gets brittle and develop cracks, well these tiny cracks will leak. But, if your sure that your front struts and rear bags aren't leaking, then it's probably the air distribution block located just behind the air compressor.
