S124 W124 Rear Self Levelling Suspension Position Valve Rebuild

[beagle2]

Hello,

Has anyone rebuilt this valve - 124 328 0031?

I’ve found a guide for a similar part on a W123 but it looks slightly different.

To get the valve new from Mercedes is ~ £400, so I’d rather rebuild if possible. Mine is weeping a bit so I’m hoping it can be rebuilt.

MB don’t offer a rebuild kit.

Thanks
