Repair Summary
The following article gives detailed instructions on performing an oil level sensor repair on a BMW E60 5 series car. Even though we have used a 2005 BMW E60 530i to perform this repair, this article can be applied to all BMW E60 and E61 5 series vehicles with minor modifications.

A common maintenance issue on the BMW E60 5 series is failure of the vehicle’s engine oil sensor requiring an oil level sensor repair. If your engine oil is at the proper level but your vehicle is still displaying  error messages and lights, your BMW E60 oil level sensor has failed. A failed oil level sensor will also generate a 27C3 fault code on your diagnostic scanner.

Sensors….sensors…and more sensors. Our BMWs are loaded with them. And as we precariously cruise through the 10 year anniversaries of our wonderfully eccentric E60 5 series cars, those sensors will start to fail. More and more error lights and messages start to appear causing anxiety and that nagging voice in our head starts asking…”should I sell this damn car before anything else happens?”. Unfortunately the BMW Repair Guide can’t make that call for you (personally we love E60s and prefer to fix them); but what we can do is teach you how to repair many of those sensors without paying a fortune at the dealership. Maybe that will sway your decision.

If you know that your engine oil level is ok and your iDrive is displaying an “Engine oil level below minimum!” warning and the dashboard oil light is illuminated, then you most likely need an oil level sensor repair.IDrive message and dashboard warning for low oil levels may be due to a faulty oil level sensor.

If you are using a diagnostic scanner, you should also show a 27C3 fault code verifying the sensor is not responding. A 27C3 fault code means you will need an oil level sensor repair on your vehicle.Typical fault codes for a faulty oil level sensor

The BMW Repair Guide highly recommends the use of a diagnostic scanner to help identify and fix issues with your BMW automobile. A good BMW diagnostic scanner is inexpensive, easy to use, and helps take the “guess work” out of diagnosing repair issues with your vehicle. The investment in a diagnostic scanner will usually pay for itself after one repair. If you are interested in using the same diagnostic scanner we use, please click here.
