What's wrong?
The cylinder head cover on the 2024 BMW 430I sits on top of the engine and seals the valve train, the moving parts that open and close the engine's intake and exhaust valves. Its job is to keep engine oil inside the cover while the engine runs and oil circulates under pressure.
In NHTSA campaign 23V863, BMW says the cover was not produced to specification during supplier injection molding. Unwanted wall-thickness variation can leave weak areas in the cover. Over time, those weak areas can form hairline cracks, letting oil leak into the engine compartment instead of staying contained in the engine.
The warning sign is a message in the instrument cluster. If that message appears, treat it as a sign that the cover has started to leak or the engine has detected a related fault.

What happens at the repair
At the dealer, a BMW technician inspects the cylinder head cover and replaces it if cracks are found or replacement is needed. The recall repair is free, with parts and labor covered. Out-of-pocket repairs already paid are handled through the BMW New Vehicle Limited Warranty, not through a separate reimbursement program. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
