Retractable roof diagnosis
Roof systems use multiple position switches, latches, hydraulic or electric drives and interlocks. Record the precise point at which operation stops; inspect battery voltage, luggage divider switches, hydraulic fluid leakage where fitted, and latch position data. Avoid forcing a stalled mechanism because linkage or glass damage can result.
Repair decisions and verification
Run complete open and close cycles while confirming seal alignment and latch status.
A roof that stops mid-cycle, leaks or reports a fault may involve hydraulic pressure, switches, position sensors or mechanical binding.
How the problem should be evaluated
Inspect fluid leakage, check sensor status and confirm the roof sequence before replacing a pump or cylinder.
Why the model and engine matter: Roof designs and components differ between SL generations.
