How to study & Clear Code for Checking BMW’s Engine Lights

The following instruction shows how to diagnose a BMW’s check engine lights. The YOUCANIC Full System Scanner or another OBD-II scanner that can read BMW-specific fault codes is preferred for diagnosing the check engine light on your BMW.


1: Find your BMW’s diagnostic ports on the driver’s side; this port is below the dash.

  1. Connect the scanner to the OBD2 connector. When you press your start buttons without you pressing your brake pedal will turn on the ignition.
  2. Allow your scanner to start up.
  3. To study code from the DME Module, press read/enter.
  4. Upon completion, please record the codes & remove them.
  5. You can only read & clear code from your ECU, DME, and DDE using this method. If you have other issues, an ordinary OBD2 scanner would not be able to read the codes and clear them.

To put it another way, a standard OBD2 scanner can only read & clear code from your ECU, not the SRS, DSC, EGS Transmission, ABS, Airbag, Stability Control, etc. modules. Keep in mind that while you are able to study the codes, you will not be able to remove them unless the issue that triggered them is resolved. If you don’t address the underlying issue, both the light & the codes will return. In some cases, it returns instantly, while in others, it may take up to two days.

Driving your vehicle at a steady speed for approximately 50 miles is another method for resetting your check engine lights. The check engine light should go out as a result of this, which will enable the sensor to recalibrate.
