  • Parking Brake Actuator - Gear inside the parking brake actuator can break. A common problem on BMW with electronic brakes that triggers the yellow PARK light to stay on.
  • Software issue -  BMW parking brake problem in some cases can be fixed by performing a software update at the dealer.
  • Loose connector - Examine the connector to the parking brake module actuator. A corroded wire can trigger intermittent parking brake errors.
  • Weak battery - A weak battery can prevent the parking brake from releasing. You most likely experience other electrical problems as well if your BMW is not holding a charge. Follow this guide to learn how to replace a BMW battery. 

Troubleshooting BMW Parking Brake Malfunction

First, try a soft reset of BMW Parking Brake.

Continue reading to learn what you will need and the steps required to perform this repair yourself. 

​​​​​What you will need

Before you begin

  • Disconnect the battery - Battery will be located in the trunk.
  • Don't operate the parking brakes if you have BMW Parking Brake Actuator module removed for repair.

Instructions

  1. Remove the parking brake actuator from the trunk. 
  2. Open the parking brake actuator housing and replace the broken gear. Use a metal gear that includes the shaft. If you buy a kit that has only the plastic gear, you will need to use the old shaft. The procedure is slightly more difficult and requires a press. See these instructions if you are installing a plastic gear
  3. Install the parking brake actuator and use a BMW scanner to reset BMW Parking Brake Fault Codes.

Further troubleshooting 

If none of the solutions mentioned above worked, the next step is to read the fault codes from the Electronic Parking module. A generic OBD2 scanner will not allow you to read fault codes related to the parking brake.

You will need a BMW specific scanner that is able to read the Parking Brake / Electromechanical module. 

Another common problem is a defective ABS module. Read the codes from the ABS, DSC module or perform a full system scan.

Follow instructions on this guide to learn how to read BMW fault codes.

Frequently Asked Questions

I checked the gear inside the parking brake module and it is not damaged, what could be wrong? 

  • If the gear is not the problem, check power going to the parking module motor as well. The problem could be the ABS module as well located in the engine bay, passenger side. To further troubleshoot this problem, we recommend read fault codes from the DSC module. Learn how to read BMW fault codes. 

Why does my OBD2 scanner show no fault code for the parking brake? 

  • Many BMW owners try to read parking brake faults, using generic OBD2 scanners. These basic scanners can only read Engine Control Unit codes. Parking brake fault codes are not stored in the ECU they are stored in the EMF module. To read BMW parking brake codes, you will need a BMW specific scanner.

Where is BMW parking brake unit located? 

  • In the trunk. Lift the carpet in the trunk. Parking module is towards the front, behind the rear seat. On some models, it is located under the trunk, next to the rear differential. 

Does BMW parking module need to be programmed? 

  • No. But fault codes will need to be cleared with a BMW scanner to reset the yellow brake light on the BMW dashboard. 

Why am I getting BMW parking brake malfunction after changing the brake pads? 

  • If you replaced the rear brake pads, you may get parking light warning on the dashboard. Start the car and pump the brake pedal a few times. Next check the brake fluid level. Once you have completed these two tasks, operate the parking brakes a few times. That would normally rest your BMW parking brakes. If not, check the sensor at the rear wheels and the cable for the parking brakes.
