Mercedes R230 SL: roof cycle stops with the trunk lid raised
Tom Diab reported a roof cycle that would finish only after he gently pushed the trunk lid down. Members considered limit switches and hydraulics, but the thread ends without a confirmed diagnosis or repair.
The roof cycle stops at the final close
In a thread titled for a 2006 R230 SL, Tom Diab reported that the final trunk-lid closing step failed during both roof opening and closing. He said he would gently push the lid down, return to the car and complete the cycle, after which the trunk locked. This describes the owner’s workaround, rather than an established repair.
Replies leave the cause unresolved
Rudeney thought the symptom pointed more toward a weak hydraulic cylinder than a limit-switch fault, while still suggesting that the switches were worth testing. Diab asked whether the switch or “pump #8” was responsible; Rudeney’s earlier guess had referred to cylinder #8. Those two labels do not establish the same component. bobterry99 discussed a valve fault or an internally leaking cylinder as possibilities if the pump ran without movement. Rudeney added that the lid push would not affect the windshield-header switches. These remained the contributors’ explanations, rather than a demonstrated fault on Diab’s car.
No verified repair result
The discussion ends without a confirmed faulty part, completed repair or later result from the owner. It therefore documents a specific symptom and the members’ diagnostic reasoning, rather than a successful fix.
