It’s great to hear about the user Ghoti’s successful resolution to their convertible top issue! Often, when a Mercedes CLK430 convertible top malfunctions, the immediate assumption is cable trouble. However, as Ghoti discovered with their 2002 Mercedes Clk430, the solution can sometimes be simpler and unexpected.
Ghoti’s update revealed that the convertible top issue wasn’t due to cables at all, but rather a loose manual override valve screw on the hydraulic pump. This valve, accessible in the trunk and operated with a flat screwdriver for manual top operation, wasn’t tightened sufficiently after hydraulic cylinder work. This seemingly minor oversight prevented the top from completing its cycle.
This case highlights a crucial point for 2002 Mercedes CLK430 owners experiencing convertible top problems. While cable issues are common culprits, especially concerning the top’s retraction from the windshield due to frame leverage, other factors are at play. The hydraulic system, particularly in older models like the 2002 CLK430, is prone to leaks, especially in the rear lock cylinders. These leaks, along with a potentially weakening hydraulic pump motor, can also mimic cable problems.
Before assuming cable replacement is necessary for your 2002 Mercedes CLK430 convertible top, consider checking the manual valve screw tightness.
