Hi

Is it the thumping noise that you get when you go over bumps like a loose parcel shelf type of noise??

Hi

Keep me posted how you get on. I intend to change the oil in my power steering/ self levelling system soon and if changing the spheres gets rid of the thumping i could replace them when the system is drained down.

Assuming it can be diagnosed on STAR why not start there? My self-leveling failed at around 90K, with the identical symptom you describe and it was a control valve at around £200. Then it failed again after another 10k with the same symptoms and it was the suspension ECU at around £700.
If it pumps up hard the spheres are holding pressure so why assume they're involved?

hi 230 yep il keep ya posted on future developments..

Hi,
You have opened an 11 year old thread, and not really asked a question. Due to the lateness of the hour, have a look at this and see what you have done and have not done.

My SLS fluid was in the same state.
A couple of months after I changed the spheres and fluid, the steering rack started leaking and had to be changed (it shares the SLS fluid).

The hard ride is caused by the Nitrogen leaking out past the diaphragm, so the entire sphere fills with SLS (a low fluid level is a clue as to what's happened)

I had the same issue on my 124 4-Matic Wagon. Replaced the spheres and flushed the fluid (smart ****) now my tandem pump is leaking. She laughs at me, mocking my attempts to keep her sweet and healthy.
