Mercedes Sprinter Engine Oil Level Sensor – Genuine OEM | NCV3 & VS30 OM642 & OM651 | #0009050401 (2010–2022)

A failed engine oil level sensor on a Sprinter removes the early warning system that alerts the driver when oil drops below the safe threshold — leaving the engine running without any indication of oil loss until it's too late to prevent damage. This is the Genuine Mercedes-Benz OEM engine oil level sensor for NCV3 and VS30 Sprinters equipped with the 3.0L OM642 or 2.1L OM651 diesel engine, a direct replacement that restores accurate oil level monitoring and proper dashboard warning function.

What This Part Does

The engine oil level sensor mounts in the oil pan and uses a float or capacitive sensing element to continuously monitor the depth of oil in the sump. It reports this data to the instrument cluster and ECU, which use it to trigger the oil level warning light when the oil level drops below the minimum threshold. Unlike a mechanical dipstick, the electronic sensor provides a real-time, driver-facing warning that activates before the level drops to the point where oil pressure is affected — giving the driver time to add oil before engine damage occurs. The sensor also measures oil temperature on some configurations, providing combined oil condition data to the service interval system. When the sensor's internal float mechanism fails, its electrical connection degrades, or its sealing o-ring leaks, the warning light illuminates with incorrect or no data — and the driver loses confidence that the warning system is functioning.

Common Symptoms of a Failing Oil Level Sensor

• Oil level warning light that illuminates despite the oil being at the correct level on the dipstick
• Oil level warning that stays on after an oil change and reset — indicating a sensor fault rather than low oil
• Intermittent or absent oil level warning when the level is genuinely low
• Oil leak at the sensor mounting point in the oil pan from a degraded sealing o-ring
• Fault codes related to oil level sensor circuit or plausibility stored in the ECU

When to Replace

Replace when the oil level warning cannot be cleared after confirming the oil level is correct, or when fault codes confirm a sensor circuit fault. Also replace when the oil pan is being serviced and the sensor o-ring shows wear or damage. Always replace the sensor sealing o-ring at the same time if not included with the sensor.
