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 partway can have interlock, hydraulic, sensor or latch-related causes.

How the problem should be evaluated

Check trunk partition and safety interlocks, battery voltage, relevant switch states and hydraulic operation where applicable.

Why the model and engine matter: Do not force a stalled roof mechanism.
