ABC Suspension Schematic
Hello,
Does anyone have a schematic and pictures of the entire ABC system on a late model W221? I was informed of a rear shock blowout by the dealer. I want to know the functionality, all parts and components involved, and expected costs. I just picked up this car a few weeks ago and am now dealing with the repairs.

2007 S600, 2007 Chrysler 300 SRT8, 2000 C5 Corvette, 2017 Mustang GT, 2023 300C, and a 2019 Lincoln
So I have ABC on my 2007 S600 now with 104K miles. When I bought the car in 2019 with 55K miles, I spent a fair amount of money on a new ABC hose, a new ABC valve block, and I flushed the green fluid several times each with a new filter. Once I got it maintained properly, I simply changed the fluid and filter every two years and watched for leaks at the shock struts. Finally after six years, the two front shock struts were replaced. I expect to have to do the rear shocks this year. The shocks were about $1400 each and the green Pentocin fluid was $20 a liter.
I had the benefit when I bought it in 2019 (an Embassy car used to chauffer the Ambassador's wife) of also buying a warranty. That warranty has now expired. Typical costs to repair a leaking ABC system run right around $6K using OEM parts if the car has been neglected. Expensive? Of course, but what mistress isn't expensive. And of course, I love mine very much. And like any good mistress, I derive a lot of pleasure. But I pay the price!
I would only comment that these cars really need regular maintenance. The ABC system is not unlike an aircraft's hydraulic system for wing flaps and slats; and they work best when well maintained with clean fluid and not allowed to sit idle for long periods of time.
And in my opinion, a well maintained W221 is the finest motorcar in the World.
Start by checking for codes and keep us posted.

So I did the entire front suspension components and control arms using an FCP Euro kit because of the lifetime warranty and then did the front ABC shock struts using OEM which are all remanufactured. After installation the car drove really well. I did need to refurbish two wheels and that was the cherry on top for the nicest drive of 1100 miles to FL ever. Next up is the rear ABC shock struts and then I am taking a hard look at that rear end carrier.
