The only problem is I'm in Australia, and I want to get the car back on the road before easter.
But if I have trouble locating a hose here I would be interested in buying yours.
Also did you see the restrictors that were pulled out of the old hose?
Thanks,
Grant.

They were a series of plastic tubes with a small orifice at one end and radial protrusions on the other to keep them centered in the hose. I think they went from end to end. Each one was about 3/4" long. Not sure, it was a number of years back.

OK went to a hydraulic hose place today (Pirtek) and the guy behind the counter knew all about the hoses on the self levelling suspension. It took 1.5 hours and $100aud and I had a new hose.
I was over joyed as MB quoted me $715aud for the hose.
Unfortunately after fitting the new hose the car now has a buzz or vibration at 2000-3000rpm and I think it's from the new hose.
Moral of story buy genuine when that's all there is, as there's probably a good reason.:(

I did find my genuine MB hose, it has been gathering dust since my rebuilt hose works fine. I am convinced the buzz you and others have described it due to the lack of orifice inserts (lack of a better name) in the rebuilt hoses. Notwithstanding, I would put up with some buzzing if it cost me 1/7 the cost of a new hose. If you are interested in the genuine article, let me know. It is available.
