A DSA or suspension warning on a European car should be inspected promptly because it can reflect an air-suspension leak, compressor, level sensor, damper, wiring, or control fault that compromises handling. Manufacturer-specific diagnostics are needed to identify the cause.
A 2006 Porsche 911 Cabriolet convertible top may stop operating when leaking hydraulic cylinders lose system pressure.
