MB’s of all kinds.
First thing is to stop driving the car and get it towed. That is a large amount of oil and you do not want to ruin the engine or hydraulic system. It’s very clear you have a leak and it needs to be fixed asap. Did you start simple by opening the hood to see where it is coming from as it could provide some easier insight? What are the codes? What warning lights come up on the dash? Is the car sitting normal?

No hydraulic fluid means it’s a ABC issue. Active Body Control. I am assuming based on post and pics that a ABC line has blown.

It's your abc accumulator near the fuel pump. Replace all 4 of them if you haven't recently and get a abc flush and new filter. Should cost about $4000 with labor.

These are the pictures of plastic cover, under this cover you have ABC hoses and fuel filter. That hoses are old and rusted, it's not too long too. My car stayed put, until I found a solution to change that little bit hose which was busted and all ABC oil was leaking out from it. I think I put here how I fixed it. I bought a $800 tool to do it though.

Its actually good news that whatever blew, it most likely blew everything to the outside. If the accumulator blows and throws metal and plastic inside the system, its a lot worse.

Thats how you fix it

If you don't want to take down or lower your back subframe,you need to cut the crimp of blown hydraulic hose from the car end carefully with a Dremel tool don't mess the pipe inside, and unscrew the reverse flange end from valve body, FB1 or FB2, or maybe the third line goes under SP. Then put a new hose with the flange end, you have to cut that crimp also but its easier because it's out of the car now. Don't crimp the new one yet make sure it's adjusted to the valve body with a new hose. Then look at my picture, that is the way to crimp high pressure hose crimps under the car.

Very lucky line

You are very blessed, that line is long but it is possible to get it out of under the vehicle. If you had one of the back side shocks and suspension tank hoses busted. You can't get those lines out without lowering rear subframe. This line can be fixed with a hydraulic shop.

Yes indeed! I tried a hydraulic shop but they wouldn't touch it so I just brought a brand new line and the self leveling filters!

Good move, replace all 4 hydraulic spheres. one on rear valve block, one on driver's side front, 2 big ones (same part number on these) for suspension. The smaller ones prevent damage to your lines from the ABC pump. If you don't replace those you will continue to have lines blow out.

Yup, on looks kind of like an old lightbulb, one has a square piece of metal on it. You'll have to google since I don't remember the numbers, shouldn't be too bad.

I usually just google for threads other people have made that have good pictures. Some have nice full-car diagrams for the ABC system.

Also I forgot to mention in last post, there is one on the passenger side front where the 2 covered lines run under the engine/trans and connect to a metal thing, which has the dampener attached to it. it's like right behind the wheel.
