there is a special oil for the self levelling system. You can buy it either from a dealer or at any german and swedish branch (£4.70 pe litre) . call me if you want to know your closest

thanks Dave
                  but like a fool i have just paid £7.15 for a litre for my local merc dealer it came with the code zh-m which means little to me, all i need is the spec and i will be able to find it at any motor store.
my problem is still how to go about bleeding the system to get rid of the old oil  the main valve at the rear has a bleed ponit but do the struts? also is it possable to recharge the two accumulators in the system or is this a case of hand in pocket tp replace them.
any one got any ideas
thnaks
