Where is pulsation dampener on Mercedes Benz W215?

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.

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.

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!!!!

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.
