Once again, never ending problems with 2004 Mercedes s600. I have replaced a ton of **** since the day I purchased it. Today I had leak from back, which I think is Part # A2203200054, the hose that goes from the rear valve to the damper. Can somebody confirm this and have any idea how to replace it and if its possible without removing the frame?

I think that this line can be done with the subframe intact. The line for the left rear strut requires moving the subframe.

You'll have to remove the exhaust system to get at that accumulator. Since you're replacing the line, I would do the accumulator at the same time.

Exhaust system is heavy and bulky, but not hard. Left muffler requires removing one clamp, the disconnecting from hangars. Right muffler (the one blocking access) requires removing a support plate (4 bolts) and the three bolts for each converter output pipe (6 total).

Looks like this once it's out. Personally, I had to cut all six clamp bolts on the converter connections. Fastenal was less than half the price of MB for flanged 10.9 metric bolts.

Astro14 appreciate the assist, I was able to get it done with out removing the muffler, and yes it was a PAIN. Removing the damper was kinda tough with the muffler in way and since i was replacing the hose which was about 3-4ft long i ended up cutting it into 3 pieces to remove it easier. Putting it back in took a lot of magic but with persistence I was able to put it back in place tighten the end to the dumper and no leaks so far. I do have picture of everything, so if somebody runs into this problem I'd gladly post it up.

I spent 4 hours yesterday trying to get this line out yesterday. Mine is a CL55 which I think means the exhaust and axles are larger, possibly the differential too. Wow what a maze of geometry. If you still have those photos I'd be interested in comparing.

On the CL55, removing the exhaust was mandatory. I tried to do it without removing the right rear muffler but to no avail. So the procedure seems to be.

• Remove exhuast from behind the cats
• Disconnect the parking brake lines from the parking break tensioner. This video shows how to release the parking brake cable tension
  You Tube
• (optional) drop the Drive Shaft. Do this if your flex discs are due for replacement. Makes it a bit easier
• Undo all the mounts for the accumulator hydraulic line you are replacing as well as the right rear side hydraulic line. This gives you the slack you need. You'll use every 10mm special tool in your kit (u-jointed, flat box-in ratchet wrench, regular socket with extension, regular box-in wrench...)
• Undo both sides of the rear accumulator hydraulic line
• Work the end of the hydraulic line by the fuel pump towards the center away from the fuel lines and other hydraulic lines
• Work the end of the hydraulic line by the accumulator forward over the axle/suspension frame. Takes some persuading...
• Slip the line out over the nose of the differential.

My pump pressurized the system despite my wife driving on it without fluid for 5 miles. Current pump has 10k miles on it so its probably going to fail prematurely, but seems to work now. Waiting on exhaust pipe gaskets currently. Damn that AMG exhaust is huge

I did all three lines without disconnecting the differential, but with removing the exhaust and lowering the subframe. The subframe is held on by stretch bolts that need to be replaced.

Still scratching my head how I can get the hose feeding the accumulator out. It requires some magic.

[edit]

Now that I think about it, I might have disconnected the e-brakes and differential for one of the lines, but I'm not 100% sure.

If anyone needs the cl500 /cl600 abc hose going to the pressure dampener I have that hose brand new as I only needed the pressure damper and Mercedes only sold it as a combined part with the hose . So I am just selling the hose without damper
