CL500 ABC Problem in 2004

[DreamCatcher88]

Greetings everyone;

As I rounded a bend on my way home this evening, the words "ABC Visit Workshop!" flashed on my dashboard. Now I'm a little confused.


Worryingly, I felt the vehicle begin to bounce and feel extremely floaty the second I received the message.

Fortunately, I was rather close to my house, so I sprang out of the running car as soon as I pulled onto the driveway and saw it sitting proudly on its highest suspension point.

As soon as I applied pressure to the vehicle, its body effortlessly jumped up and down.

I returned to the vehicle, shook off the shock, and then shut off the engine, waiting a minute or two before starting it again. The automobile rose up without a hitch when I clicked the raise button; but, when I got out, it was obvious that the suspension was still set to its highest setting, and the bounce was still present.

There were no longer any cautions because the ABC message on the dashboard had vanished.

The original warning had white text instead of red. If anyone has any suggestions, I would greatly appreciate it because I had the rear shocks changed approximately four months ago.

The vehicle's front and rear ends are still elevated.

Much obliged.

There were instances where valves had to be replaced due to struts being jammed when the ABC-system was implemented. Mercedes came up with the "Rodeo test" after giving it some thought.
Using Xentry, we subject the system to stress by jolting the vehicle and listening to its vibrations.

problem codes. By evaluating the ABC system's capabilities, any malfunctions are exposed.

Additionally, the rodeo test "lubricates" the struts and valves and removes any dirt from the oil system.

Changing the ABC oil (and filter) at normal intervals is crucial. There was absolutely no interval mentioned on the M/Y2000, at least! In its original state, hydraulic oil is odourless, translucent, and verdant. The time for changing has come if the oil is cloudy, smells bad, and has a greyish hue. The filler cap is where you can find the filter. Upon completion, it turns white (or a pale green).

The pulsation damper is likely to be worn out after around 10,000 kilometres. Testing it is a breeze.
Turn the engine over while it is at a complete stop in neutral gear. To replace the pulsation damper, listen for a rumbling sound that goes away when the engine speed reaches around 1800 RPM.

Making sure the ABC system is in good working order is crucial. Metal fragments might enter the system if the pump were to break due to contaminated oil. Fixing it will cost a big penny. Before anything else, make sure the oil is clean on any CL (or prospective purchase).

Parking a vehicle that gradually lowers itself is OK, but only up to a certain point. I raised my CL, placed a bundle of wood blocks behind the service pads, and then dropped it to store it for the winter. Therefore, there was no strain on the struts and the tires did not become flat.

An ex-MB technician named Alex from legitstreetcars.com is currently tackling a V12. You may find his work on the ABC system and how to remove and strip down an engine to replace a £1 'o' ring in his content.


Although you can jump to the parts concerning ABC, it is worth watching all of his films that deal with the CLK.

Not everyone is brave enough to deal with issues with earlier ABC systems. My wish is that you uncover the truth.

I noticed the body was sitting at its normal height the second I stepped outside today, so I went ahead and checked to see if it would bounce. It did not!


I started the engine carefully and saw no warnings, so I went for a short run to make sure everything was OK.

The car handled and drove perfectly without my touching the height/lower or sport settings; I figured it was best to just let it be.

Upon returning home, I verified that the ABC fluid level was sufficient; nevertheless, it appeared somewhat low on the dipstick, not quite full but not quite empty either. Is it possible that this is the source of the problem? If so, which oil or fluid should I get to replenish it? I was searching online, but there seem to be a lot of options.

Much obliged.

A fluid checker is available on the Opie Oils website.
It's called CHF11s or something similar, and MB Parts will sell you a litre of it.

Would this be the one?

This is where I purchased mine from the MB dealer. The name you should ask for is pentosin.

I posted a video of Legitstreetcars; you should watch it. You can see the oil can that Alex uses.
