Where is the pulsation dampener on a Mercedes Benz?
The ABC component most likely to cause this noise is the pulsation dampener. The location varies by model and year. On the R230 it is located in the front-left wheel well. On the W215 it is attached to the undercarriage near the transmission. On later models with the updated ABC system (2007+), the pulsation dampener is on the ABC pump.
What should I do if my ABC pump stops working?
If so, do not start the car again until you have added more fluid and restored normal pump operation. If you attempt to drive the car without adequate fluid, the pump will be destroyed in very quick order (a $2,500 repair), while shedding metal debris into the system that will damage other components as well.

On later models with the updated ABC system (2007+), the pulsation dampener is on the ABC pump. Replace the dampener. Cost is around $175 and is a relatively simple DIY project. Or around $600-800 if you have a shop do it.
Where is the ABC pressure limiting valve located?
On the bottom of the ABC pressure limiting valve is the oil pressure sensor and on top a pulsation damper which smoothens out the pressure fluctuations of the system.

When did the ABC system start on my Mercedes SL500?
In July of 2014, I purchased a used 2003 Mercedes SL500 with 80,000 miles on it. And within days the infamous “ABC Drive Carefully” message started appearing on the dash.
Where is the pulsation damper and return accumulator located?
QUOTE=Deplore;15152057]Ditto to above — two accumulators in the rear are both on the valve block, one accumulator is on the front valve block, and the pulsation dampener is behind the left front wheel, accessible by removing the fender liner. The ABC pressure sensor is also located there, so it’ll be obvious.
What happens if I Drive my Mercedes without the ABC pump?
If you attempt to drive the car without adequate fluid, the pump will be destroyed in very quick order (a $2,500 repair), while shedding metal debris into the system that will damage other components as well. It is NOT worth trying to drive the rest of the way home!!!!

Why is my ABC system not working properly?
Stopping and starting the car sometimes resets things back to normal for a while. The pump is weak, resulting in inconsistent performance. Sometimes the ABC system reaches operating pressure, sometimes not. A strut travel sensor or ride height sensor may be going bad. Some motion from driving gets it working again.

How much does it cost to replace ABC pump?
-Inconsistent and vague suspension. Mercedes here quoted $7k for the ABC pump, plus $850 to flush the fluid. They also wanted $3k for the pressure accumulators and $2750 for the front left strut. I replaced all the pressure accumulators for around $600 but still got the ABC warning.
What’s the problem with Mercedes Benz ABC system?
The ABC system noticed a problem when starting up and has disabled itself, locking the struts in their current position. This may result in what many people describe as a “tuna boat” ride (very bouncy). The system has a fluid leak and the fluid level in the reservoir is extremely low, preventing the system from getting up to operating pressure.

Why does my Mercedes Benz make a whine when out of gear?
You can hear a hum or whine under 2000 rpm. Is present both in gear and out of gear. The pulsation dampener has worn out. There are lots of pumps and other non-ABC components that produce noises like this on these vehicles, so try to located the source of the noise using a stethoscope or long screwdriver.
