The BMW F10’s oil level sensor is a critical component for maintaining engine health. A faulty sensor can provide inaccurate readings, leading to potential engine damage. This guide provides a step-by-step walkthrough for replacing the oil level sensor in your BMW F10.
Replacing the sensor yourself can save on labor costs and ensure the job is done correctly. While the process requires some technical knowledge, this guide aims to simplify the procedure. This specific replacement was performed on a vehicle with only 600 miles on the current oil, highlighting the importance of addressing a faulty sensor promptly.
Replacing the BMW F10 Oil Level Sensor
Before starting, gather the necessary tools and parts:
- New Oil Level Sensor: BMW part number 12617607910 is recommended. Sourcing from a reputable supplier with a good warranty is advisable.
- Fresh Engine Oil: Approximately 9.5 quarts will be needed.
- New Oil Filter: Replacing the oil filter during this process is standard practice.
- 10mm Socket: For removing the sensor retaining nuts.
- Tools for removing the oil filter housing and drain plug.
- Tools for removing the metal undertray protecting the oil pan.
Here’s a detailed breakdown of the replacement process:
Draining the Engine Oil
- Warm Up the Engine: Allowing the engine to warm up slightly will help the oil flow more freely.
- Remove Oil Drain Plug: Loosen and remove the oil drain plug from the oil pan, allowing the oil to drain completely. Loosely reinstall the plug.
- Remove Oil Filter Housing: Remove the oil filter housing to further drain the remaining oil. Loosely reinstall the housing.
Accessing the Oil Level Sensor
- Remove Undertray: Remove the bolts securing the metal plate protecting the oil pan. Removing all but one bolt can allow enough flexibility to access the sensor without completely detaching the plate. Note that some bolts securing a plastic shield may also need removal.
Replacing the Sensor
-
Remove Sensor Retaining Nuts: Using a 10mm socket, remove the three nuts holding the oil level sensor in place. Expect some oil spillage during this step.
-
Disconnect Electrical Connector: Press the tabs on the electrical connector and gently pull to unplug it from the sensor.
-
Install New Sensor: Connect the electrical connector to the new sensor. Secure the sensor to the engine using the three retaining nuts.
-
Reinstall Undertray: Reinstall the metal plate and any plastic shields removed earlier.
Refilling Engine Oil
- Replace Drain Plug: Remove the drain plug again to drain any accumulated oil. Install a new drain plug with a new crush washer and tighten to the specified torque.
- Install New Oil Filter: Install the new oil filter and secure the oil filter housing.
- Add Oil: Lower the vehicle and add approximately 9 quarts of fresh engine oil.
- Check Oil Level: Warm up the engine and check the oil level using the dipstick. Add oil as needed to reach the maximum level, typically requiring about an additional 0.5 quarts.
Conclusion
Replacing the Bmw F10 Oil Level Sensor is a manageable DIY task with the right tools and guidance. This guide provides a comprehensive approach to ensure a successful replacement. Always consult your vehicle’s service manual for specific torque specifications and recommended oil types. Regularly checking your oil level, even with a new sensor, is crucial for maintaining your BMW F10’s engine health and longevity.
