97. E-300. Td. 7 seat. Est. Rear suspen. Bumpy ?

[HERBIEMERCMAN]

hi everyone, my vehicle has a hydraulic self leveling suspension system with oil resavoir and a belt driven pump. recently the oil level in the oil supply resavoir has risen 2cm.above the max mark, the rear suspension seems to have lost it's cushion effect, it's bumpy. history,some months ago prior to me having any problems my local garage changed all the hydraulic pipes as one of their mechanics mistook them for brake pipes and destroyed them. he also sent a veh. out without gearbox oil and was dismissed. the cost of new pipes and fluid cost me £150. and some messing about, merc. won't supply the pipes, and we tried copper pipe, which leaks due to diff. expansion. as the pipes get hot, had to order 6mm bundy and make a flaring tool. as far as i know my garage, who are very good, bled the system at the valve just above the rear axle. does anyone know what could have gone wrong shortly after the work was done ? herbiemercman.

I will have a look to see if there is any special way to fill it

As the rear sink,then it will push the fluid back to the filler tank, so the pump is not pumping.

Are the pipes all good at this point in time

hi malcolm, all pipes are good with the majority replaced last year. could the system just need bleeding? presumably this would have to be done with the engine running. when the system was working prior to the pipes being changed they used to get quite hot, so i suppose i could check if the pump is working by feeling at the pipes.herbiemercman.

hi malcolm, my local garage friend tells me the spheres are gone, i contacted my friend at dronsfields and he said for the cost differece he would fit new ones, it is also not possible to test secondhand sheres other than driving the car. i have ordered them from mb main dealer. £110. inc. vat. each. ian. herbiemercman.

Changing My rear spheres as well

My 93 220TE is getting its spheres replaced this weekend ( if weather is dry ) by myself, following the procedure posted by Andy _k I've ordered the spheres, 2 new pipes ( the ones from the sphere to the levelling unit ) ie not the expensive ones. and some seals. got a shopping list for nuts spanners etc
So would be interested to hear any additional feedback from anyone who has done this job.
Thanks
