I recently gave in and got help R&R ing the rear ABC lines. The tech removed them and put them back in. I sent them to the hydraulic line rebuild shop and gave them back to the tech. Now when I go program the ride hight the rear suspension is reversed. I try to level the right rear and I have to use the left rear buttons to do so. When I try to drive the car it either forgets the level and defaults back into the right side jacked up and the left slammed, or the sensors freak out knowing the lines are reversed. The question here today is, did the tech reverse the lines or did he reverse the "plugs".

I just did the front ABC block rebuild and made the same mistake. The car would slam down on one side. Then I switched the plugs that go into the block and it was good until I blew out the rear hose(s). Is it the same thing?

Take a look under there and see if they are swapped?

I didn't take them down and wouldn't know if they are reversed. I'm going by the fact that I need to hit the "left rear" button to raise the right rear as an indicator. Is there something else that would cause this? The tech said he didn't disconnect the plugs.

Some of the lines have colored bands that line up with the respective solenoid. The connectors on the valve block are interchangeable so if you have enough slack you can easily swap those around and leave the lines. This pic is what it looks like, you can follow the lines to see where the other end is

THANK YOU! Wow that is a clean car... I wondered if swapping the plugs on the solenoids would work We went ahead and swapped the lines. The car is back in action! Man I miss driving that car. Only issue now is that on very bump I'm waiting for the "pop, hiss and tow". I did have all the rear hoses rebuilt so that's done. I'm praying the remaining ones on the front will hold out for a while. I really really appreciate everyone here who helps us MB fiends keep the thrill going.
