Description
The Mercedes-Benz Oil Level Sensor O-Ring (Part Number: A0249977445) is a genuine OEM sealing component designed to provide a leak-free seal between the oil level sensor and the oil pan. It prevents engine oil leaks while ensuring the oil level sensor remains properly seated for accurate readings.
Manufactured to Mercedes-Benz factory specifications, this O-ring offers excellent resistance to heat, oil, and engine chemicals. A worn, flattened, or hardened O-ring can cause oil seepage and inaccurate sensor readings. Replacing it with an OEM-quality O-ring restores proper sealing and helps maintain reliable oil level monitoring.
