Hello I have a 02 cl500 with suspension issues trying to figure out this weird problem . Front right passenger along with right rear goes down within an hour when I start car does not lift on that side unless I put in gear no warning lights are on????

Have it tested. It is more than likely an accumulator or the auxiliary pump or one of your struts may have failed or it could be a sensor or even a block. That is why you spend the 125.00 for the diagnosis. Then take it to a reputable repair shop, that has worked on these cars before and can do a Rodeo on it, once the parts are replaced. If you keep driving as is, you are bound to damage more and more parts, even shout out the main pump.

Pump has been replaced ..front and rear block been replaced rightt front and rear struts replaced but was used..

classyma

What type of auxiliary pump are u saying it might need? Water pump replaced too

This is the full layout of the system. There are 4 accumulators They all hold pressure and are filled with Nitrogen (which deplete over time) due to varying factors.


1) at trunk
1) at front block
1) at rear block
1) at dampener

The front right passenger accumalator has been replaced that sits close to the tire wheel..When I replaced rear block it came with one but I dont remember replacing the one on front block near left tire wheel nor the rear air cells.. one how many in all are on this car?

I dont think it is the Accumulators, they are only there to absorb heavy spikes in the pressure of the fluid. A no functional Accumulator will normally give you a red light when going over big bumps and then go away.


Since it is both front and rear, I think it sounds like a abc block that needs to be cleaned.

Unless, he finds someone to do it, most wont. I don't think he would spend the time to do it himself. Plus you have to have a lot of tools to do this big of a job, then it would need to be put on a Rodeo. Like I said, I would take it to the dealer and let them deal with it or at least tell him what is wrong. I personally think the fluid in the system should be flushed every so often and a new filter replaced. I find this will keep debris from contaminating the system. It could be very minor or it could be something major. If he can get out for less than 1,500.00 he should count is prayers.

Sorry guys i am a female. Let me tell you what i have replaced since i had this car.. front an rear blocks, front right accumalator and front right passenger and rear struts, the pump has also been replaced.. i did take car over the weekend to a shop a friend referred me to a RODEO was done to try to determine why after an hour or so the car start to lean on right side and i was told the front right side was a -6 in the the readings from the rodeo being done not really sure what that means said it also gave a pump code but he said it was not showing any systems of a bad pump so he will have to put it up on rack and take those wheels off on that side to further diagnsos problem..I came to this site cause im sure im not the only one with issue like im experiencing so any input is well appreciated

biker349

you say you replaced both valve blocks, but it sounds like that is the problem. anxiously awaiting results.

classyma

yes i did replace both and system was drained and RODEO redone

classyma

i changed out the front and rear block because it use to give a code on the right front and rear of strut still moves even thought valve is closed

classyma

Prior to changing out the blocks the car would still lift on the right side even thought it was leaning but it also gave the red car too low light at start up now it wont lift on that side at start up only when put in gear or with lift button inside car no Red lights. .

If Mercedes cant figure it out change dealerships. Hope you have another one as close to where you are. We have MANY to choose from here. You have to get a tech who knows what he is doing and has done a lot of these. It could be electrical but I am thinking you have a bad body sensor that isn't showing up enough to send a signal. I am sure at this point you are frustrated as I was. Leave it a day or so, so they can put the computer on it while it is on the ground and then see what codes come up. I think that is your only option at this point.

You said you replaced the struts with used struts - that can be the problem

Did you replace the valve blocks with used valve blocks too?

As others have said you need to stop going to a independent mechanic who puts in used parts and go to the dealer

classyma

Struts was used with warranty EBAY ...valves rebuilt got parts own my on not shops fault! Sometimes the cheap way is not the best way and not all used parts are good parts a learning process for me that is why i got on here car drives great other than the leaning issue which will soon be resolved..

Used parts are always a bad thing. Rebuilt blocks are just as good as new. The replacement blocks are the redesigned ones from the W216 and they are for the most part trouble free. The struts from Arnott are the way to go if they need replacing. They warranty them and they use a better seal on the strut cylinders. If you buy used blocks or rebuilt blocks buy the later version ones. Let us know what MBZ has to say. Best of luck!
