• No oil warning alarm during test

• Intermittent warning horn

• Warning horn stays on with correct oil level

• Damaged or corroded module wiring

• Oil warning function returns when a known-good module is fitted

• Module replacement required after oil-injection warning-system diagnosis

📦 Condition
