Where is the ABC pump on a Mercedes Benz?
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. 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.
What do you need to remove ABC pump?
Disconnect the electrical connector from the ABC pump. Remove the 2 etorx bolts on the front of the ABC pump.

How can you tell if your ABS pump is failing?
This is the most obvious sign on our list, and is by far and away the most common sign that your ABS is suffering from problems. On newer cars look for a dedicated warning light that is usually orange or amber in colour and has an ABS mark on it. Older cars may use the check engine warning light to indicate problems with this system.
How is the ABC pump held in place?
The rear of the pump is held in place with a nut through an engine bracket onto a captive stud in the pump. In order to access this nut, you need to remove the cylinder that the banjo bolts go into from the ABC pump. It is held in place by 2 etorx bolts which are not so easy to access.

-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.
When to replace an accumulator in a Mercedes Benz?
If it starts to drop and the messages start coming more frequently, then you have blown an accumulator. Pull and inspect the front and rear axle accumulators – each are part number 2203270115 (the large ones). It’s likely both are blown. Replace as necessary. The life expectancy of these accumulators is around 10 years or so.
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.

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.
