In this step-by-step guide, you will find instructions on how to replace the convertible pump on Mercedes-Benz soft-top and hard-top convertibles such as CLK, SLK, SL, E Class convertible, etc.
Common symptoms indicating the convertible pump needs to be replaced:
Hydraulic lines completely disconnected.
You do not need to bleed the air from the cylinders or lines. The system will return the air back to the reservoir as you cycle the convertible top a few times. Top off the convertible top fluid level and add more fluid if the level drops below the min level.
