The electronic oil level sensor is giving a faulty indication, by using E 20 engine flush chemical, can I clean the sensor and clear the fault?

  • Looks like dude just asked if you can use E20 flush to clean an oil level sensor in a 525i. That's what I got, anyway.

  • Clean the sensor and check the connections - if the fault is still there then cleaning did not work... Replace...

You will need to replace the oil level sensor, the sensors go bad internally and cleaning will not fix it, do a google search and you will see that it's a common problem.
