Hello all, is there a quick and easy fix to level my 2011 R230, 550Sl? Left side is higher then right side.

On the front you can remove, rebuild, and replace the blocking valve that revents sag on that side very easily without removing any hoses. Not sure about the rear.

Just saw a video on swinging the rear valve block assembly out so it can be removed, but you don't have to remove it if you only want to take out and rebuild the blocking valve.

Above are for the R230 as on my 2004 SL500

Thanks!

In my humble opinion, age has more influence than miles. The age causes the seal to harden and the rubber to swell and as this system has plenty of these components, the failures will come with the time..! But, if you like the system, rebuild and be happy...!
