ACTIVE Suspension 1/2 Alive - Left side Dead - Right Side Alive

[lino]

My car is riding on a slant now. My passenger side is higher than normal height and the driver's side is lower than normal height. I don't know why this has happened.

Here is a pic

Lino.... I am moving this to IOM. One, because it is where it belongs. Two, because Keith frequents IOM more often, and you really need help from him.

Did you run self diagnosis yet?

Sorry, I didn't mean to post here and thanks for moving it.

Self diagnosis this morning came back with code #11.Self diagnosis this evening after topping off Hydraulic Fluid and swapping instrument cluster came back code #55.

When I run low on fluid... it ALWAYS takes my system a day or two before it gets all worked out.

I get lots of funny level changes, creaks, groans, and tilted driving. Usually, though, a day or two later it is fixed.

Also, I find that letting it idle on a level surface without driving it for 15 minutes will help the system get back to normal.

Finally, my system seems to react VERY slowly when it get truly cold outside. When it was -10 last week... it felt like my suspension was moving in s-l-o-w m-o-t-i-o-n.

Every time I top off the fluid, the suspension comes alive on the spot. The lifts up right away. That's how it's been for me.

Well I hope that's the case for me. Today is day 2 and still no change. The green light in the dash lights up when I switch to high, but I just switch it back, because the left side of the car is too low.

I do have groaning from my multivalve unit. I think I'm going to get ready to replace it since I already bought a spare unit. I hope this doesn't require a lot of work.

Also, I find that letting it idle on a level surface without driving it for 15 minutes will help the system get back to normal.

I'll try that. I let it say for 10 minutes this morning, maybe I should give it more time. My car always sits on a level surface. I park it in my garage evey time I come home, and that's where it spends most of its time.

.Finally, my system seems to react VERY slowly when it get truly cold outside. When it was -10 last week... it felt like my suspension was moving in s-l-o-w m-o-t-i-o-n.

I never noticed if my suspension does that. We've been fortunate up here with the weather. Today 28° and tomorrow 37° and no snow. Truly unbelievable!

The thing that I notice is after approximately 3 seconds of turning off my car, the front right of the car drops suddenly and then the car is level, but lower than normal.

TexasOil and Q45tech have mentioned it takes several cycles to get the air out of the system.

Lino, souonds like a vavle problem to me on your front end.

Fill out your profile and it will help Everyone diagnose your problems.

did the groaning from MV just start, or has it been a while? MV *could* be groaning because of the pressure imbalance in system. MV could also be bad. I've replaced 1 and will do the second pretty soon.is there a height ofset when car off? does the 'H' position raise all 4 corners the same amount (offset remains)?talk to Keith--he will prolly suggest a few things before you change the MV.

The multivalve groan has been intermittent from before this problem. I rememer it happening the day I changed all of my accumulators and flushing the Fluid A. When it happens it only lasts for like 5 seconds. Somtimes it happens twice a day, sometimes not even once a week. It's an awful sound though.

I bought what was supposed to be a multivalve unit recently from someone in Florida, but it turns out the person sold me the front control unit. I just realized this yesterday. Keith confirmed it.

is there a height ofset when car off? does the 'H' position raise all 4 corners the same amount (offset remains)?

There is a slight height offset when the car is off.No, the "H" position does not raise all 4 corners the same amount. Wha happens is this:

Car off:

Front Left 3 finger gapRear Left 2 1/2 finger gapFront Right 3 finger gapRear Right 2 1/2 finger gap

Car running:

Front Left 3 finger gapRear Left 1 finger gapFront Right 5 finger gapRear Right 3 finger gap

talk to Keith--he will prolly suggest a few things before you change the MV.

I've been talking to Keith and he had me to some tests and then asked me to check the height senor on my front right to make sure it is not loose or on a higher-than-normal setting. Also, he suggested buying some LubeGard Red and using half a pint in the system. I already added the LubeGard yesterday afternoon.

I know this is redundant... but, I just want to make sure.

Are you checking the self diagnosis each step of the way? Also, are you following FSM instruction for clearing the diagnosis. IIRC, the computer will continue to give you the same errors even after you have fixed them unless you clear the computer.

If this were happening only while the car were running, I'd be inclined to think that this was a G sensor issue. But, since it stays that way when engine is off..it must be something to do with the way the system is channeling pressure to the different units.

The problem, though, is that if you have a bad multivalve unit and it is supplying too much pressure to front left, and not enough to right rear...your computer should still pick that up with the sensors. You'd think the system would be rasing and lowering all the time as the computer fought to get the car level based on what the G sensors were telling it.

I'm getting a code 55. That's the only code I'm getting now.

Just to remind you of the parts I already changed:

9 accumulators courtesy of KeithFront Vertical G SENSOR - Brand NewFront Lateral G SENSOR - Brand NewFront Fore and Aft G SENSOR - Brand NewRear Lateral G SENSOR - Brand New

Also, I found the spare multivalve unit that I thought that I didn't have. Maybe if all goes well, I'll get it installed tomorrow morning when I go to check my Height Senors.

This is what it looks like:
