Specifically:

(4) Accumulators intended to function as shock absorbers, struts, gas springs, pneumatic springs or other impact or energy-absorbing devices are not subject to the requirements of this subchapter provided each:

(i) Has a gas space capacity not exceeding 1.6 L and a charge pressure not exceeding 280 bar, where the product of the capacity expressed in liters and charge pressure expressed in bars does not exceed 80 (for example, 0.5 L gas space and 160 bar charge pressure);

(ii) Has a minimum burst pressure of 4 times the charge pressure at 20 C for products not exceeding 0.5 L gas space capacity and 5 times the charge pressure for products greater than 0.5 L gas space capacity;

(iii) Design type has been subjected to a fire test demonstrating that the article relieves its pressure by means of a fire degradable seal or other pressure relief device, such that the article will not fragment and that the article does not rocket; and

(iv) Accumulators must be manufactured under a written quality assurance program which monitors parameters controlling burst strength, burst mode and performance in a fire situation as specified in paragraphs (f)(4)(i) through (f)(4)(iii) of this section. A copy of the quality assurance program must be maintained at each facility at which the accumulators are manufactured.

I have just received from parts4export 3 front accumulators which are advertised as Lemforder but are actually Febi with the number 03279 space whith a H encircled then number 00378016/75. From the discussion above these sound inferior to the Lemforder advertised. My question is should I fit these? Any help would be appreciated.

Welcome to TK Peter, I don't have an answer to your question but others more voiced in 6.9 matters will chime in (I have a 6.3 and a 450SE so they let me play here).
We are almost neighbours, I live in East Kurrajong

Hi Peter,

As far as I know, Febi and Lemfoerder are as good as each other...
Only the Godfather (STYRIA) might be able to correct me on this one.

Peter, if you've bought them, by all means fit them. I mean really, what else can you do? They are really too expensive an item not to utilise them. Personally speaking from past experience, I have found the longevity factor applicable quite disappointing - after about two to three years (3 max.), you're starting to notice that ride quality is being affected. In the olden days, you'd count on a working life of about eight to ten years - that was the time when 6.9 units carried their own part number. What you're buying today are W126 units. In closing, Lemfoerders are my preference. Regards, Styria

Thanks abl567, Michel and Styria,
I have ordered rears also and when I receive these I will fit them all.
Previously the rears were replaced in 2007. The car presently drives like a pogo stick in motion. I will let you now what the rears were when I remove them.
Regards,
Peter

I'm pleased the air bellows for the far superior air suspension on the legendary 109 chassis automobiles last much longer than that

I have received the rear accumulators, these were Lemforders. I am about to start the replacement. The advice I have received indicates I should clean the reservoir. My question is can I reclaim some of the fluid to reuse?
Regards

Further to reusing the hydraulic fluid, if I want to replace all the fluid @ $60/litre for genuine MB fluid it could be quite costly. Penrite have equivalent MB343 and MB345 but the MB manual quotes MB344, what is the recommendation by those who know?

You could save fluid, but it will more than likely be aerated. Once you crack the lines, you will probably lose most of the stuff anyway. The little you might save is not worth hanging on to. The Reservoir - to clean that properly, you will need to remove it from the car altogether. It is surprising how much sludge you're likely to find in the bottom, usually reachable by swilling it out several times, probably with Kerosene.

In order to remove the reservoir, you will have to disconnect the hosing from under the front guard, and leave it attached to the reservoir. There is no way that you can disconnect the hose from the reservoir whilst in situ. Get yourself some new hosing whilst you are at it - the old staff will be hard and brittle. Good luck with the job.
