Recently i thought my steering was getting heavy, which might be a sign for the pump wearing out, which is not good as it shares the pump with the suspension.
Had a Rodeo test on it and it showed everything to be perfect. Its the best thing you can do for yours, it will show just how quick the pressure drops and how long it takes for it to build back up again.
Mine was taking a long time to drop but then only taking seconds to build back up again. If it was the other way round i think i would have sat in a corner and cried like a little girl.

Interesting to read. Please keep us updated.
My driver rear strut is leaking a bit. I'm trying to hold off a bit til I can replace it. I'd like to be able to just replace the whole system when I can get the money next year.

You most likely have a rear valve block issue. At my indy, I was charged 1550 for replacing the block. Currently my ABC is leaking (leaving oil residue on the ground) and is in the shop for repairs. 1k To repair that lol.
The car is not slammed but steering is much harder, and this is why I suspect you have a rear valve block issue. Have a professional replace, top fluid and perform rodeo!

Did you look under the car and see exactly where the leak is coming from?
The valve block overhaul is an easy DIY, cleaning and O-ring change.
If the strut is leaking, then you have to exchange it - i've seen on ebay

with core exchange its 2K. Not a bad price if you ask me.

At the dealer you're likely to pay around $1300 per strut.
Only issue I see here - S55/S65 AMG's have AMG tuned ABC struts that are different than those on the regular S-Class. I doubt this company would provide you with AMG tuned ABC struts.

AMG cars have an "AMG" logo on the bottom of the strut.
Regarding the part numbers, they are different.
