ABC hoses
Best to my fellow w215 ABC forum friends.
There are at least ten abc hoses and all of them are past their life expectancy waiting to fail. It's not a matter of preventive maintenance , Mercedes was never going to suggest to owners that all hoses should be replaced every two years . Frequent inspection and immediate replacement of any leaking hoses is key
You can't just drive the car with a abc leak , like you can with a long term small engine oil orvtranny leak and just live with it
I watched all the hydraulic fluid spray out from the bottom of my car. When I
eventually towed it to my Mechanic, he quoted me over $1000 to replace that
specific hose. Plus it also looked like the rest of them were on their way out too. Mercedes quoted over $4000 for the complete parts/hoses that I would need to rebuild my ABC. That did not include labor & any other misc. parts.
That's when I had to make a decision to go full conversion strut coil? Or just get rid of the car? I was not in my right mind to blow over $5000 on a 13 yr old car.
My car is full strut coil conversion (Strutmasters). I did the complete install
myself and eventually replaced the ABC pump to a conventional power steering pump.
Its bad news when an ABC hose fails, and it happened to me three years ago. In hindsight I could have avoided it by inspecting all the vulnerable hoses.
"Vulnerable" means anything in the oven - er - engine compartment, and "inspect" means take the covers off and do a quick visual.
If a hose is damp around the crimped joint, its telling you that it's about to fail. Sure enough my pulsation damper hose seeped, and I ignored it , and it failed.
Surprise.
There's lots you can do to manage ABC, besides go the MB dealer. Like read my thread below

The only way to repair them cheaply is to diy or use an Indy mechanic willing to cut off the metal ends and repair the hoses rather than replace them using generic hydraulic hose from a hydraulics /forklift shop
See welwynnick thread that's what he did

You can get a hydraulics / forklift shop to fabricate them?Well over 2000 psi running through the hoses when under pressure.
I just don't want my Mercedes Brothers to think that you could just get
hydraulic hoses and install fittings using hose clamps. It will not work..
Trust me....lol..They will burst.....The fittings have to be crimped on the hose with special machines.....
Mercedes OEM Hoses are very expensive here in Toronto Canada.
I was quoted over $4000
I actually had one hose fabricated by a local hydraulics shop and it worked amazing great.
The problem with my CL55 is that the whole ABC system was starting to deteriorate.....plus my pump was starting to go again for the second time.

I actually think the suspension & handling is fine.
If I was going to be tracking my CL, I'd consider doing some kind of mod
but for now my car's suspension is great. Only problem is that I don't
have the option of lowering my car like before......and my front end is a bit high......Other than that, I'm happy overall with Strutmasters....
The yellow speed coil overs should allow lowering
No one has tried them yet and posted about it

Dirt cheap, industry standard, 3/8" two-wire hydraulic hoses off the shelf of any hydraulic shop anywhere in the World will work just fine. And you can use compression hose fittings, so no need for custom pipework. Reliable.

You have individually cut the necks off all your existing hoses , take them to the hydraulics shop , then attach them to the cut down metal necks of the oem hoses. The hydraulics shop isn't going to do that to your car for you , that's all labor you need to do yourself
There are ten of those, and I replace all mine for about £300.
The flexible hoses at the back of the car are much less likely to fail.

I don’t want anyone to get me wrong, the CL’s Active Body Control is amazing technology but when our cars become a bit older this stuff breaks down.
There is tons of preventative maintenance you can do but hoses/valve blocks/ABC pump & filters/fluid inevitably will fail as our cars age…..
I met this older gentleman at a gas station last Summer. As he was admiring my CL55, he approached me and said, “I respect you for driving this car”!
He told me that in 2003 he bought a brand new CL55. The car at the time was sold to him for over $125,000 CND from Mercedes. He said that it was
his favorite car of all time and that he had to purchase it. For the first 3-4 years of ownership the CL was fabulous. Thereafter the car’s
maintenance was unreal…..Not wanted to give up on his dream car, he paid over $25,000 trying to maintain & keep his car on the road. Finally 5 years, he
gave up & sold it for peanuts.
He told me that he didn’t regret buying it because he loved the power and style but eventually maintenance costs killed it for him!
He’s now driving a newer E63 Wagon……….. “Atleast he’s 100% Mercedes Loyal”……..lol

If this car had a coil spring suspension from the factory it's resale value would be double . But aftermarket coil conversions do not help with value
My 1991 Lexus Soarer is the first production car with active suspension, but the active option cost almost as much as the car, and they only made a few hundred.
The W215/220 were the first MASS production cars with active suspension, and we're all guinea pigs here.
Old S600's are certainly troublesome, but if they were that bad, they'd be worth less than V8's, and I don't think that's true.
If they had coil spring suspension, I'd be driving something else.
