Things To Know Before Repairing A BMW Active Grille

BMW’s active grille found in certain cars from the vehicle manufacturer should improve aerodynamics when needed. Plus, it may also help increase fuel economy by reducing drag. The grille also helps in controlling the car’s climate control to provide optimal comfort for the people in the cabin.

However, attempting repairs to this feature if it malfunctions or breaks often requires following proper safety protocols. Abiding with preventive measures can reduce the risks of accidents and injuries before, during, and after fixing the issue with the active grille.

Some safety measures that should be in place are:

  • Always wear gloves. You’re going to work with parts near the engine, and gloves can help reduce the risks of burns and cuts while repairing the active grille.
  • Avoid smoking. If you need to smoke, go away from the work site and only return when you finish.
  • Don’t bring flammable items near the repair site. The heat near the engine may cause these objects to ignite.
  • Organize your equipment and materials as you work. Don’t leave items scattered in and around the job site to avoid slips and falls.
  • Clean spills immediately. Leaving fluid leaks on the floor may put passers-by at risk of slipping and falling.
  • Remove accessories like rings and bracelets. These items may snag into certain parts as you're working with the vehicle. 

Also, assess your current knowledge and skill concerning automotive repairs. Request help from reliable industry professionals if you believe that you're not up to going through this repair procedure using DIY techniques.

DIY Instructions To Replace The Actuator Of A BMW Active Grille

Step #1: Secure The Vehicle

Park your BMW on a site with flat and level ground. Engage its hand, parking, or emergency brake afterward. Also, don’t forget to turn off the engine. You may also chock the wheels if you want the added security of preventing the car from rolling while you’re working on it.

Step #2: Remove The Grille

Open the hood and use a panel remover to press the three clips on top of the grille. Applying sufficient pressure to these clips should loosen the grille from its mounting position. Then, pull out the grille and set it aside temporarily.

Note: Removing the grille from its mount may require some amount of strength. Request the help of a stronger individual if you’re having difficulty pulling out the grille from the vehicle.

Step #3: Expose The Actuator

Remove the clips securing the cover above the aluminum panel in the engine block. Unthread the bolts securing the aluminum panel and pull out the rod on top of it. Remove the panel and set it aside temporarily afterward.

You should now be looking at a long hard plastic cover. Pull out that encasement and set it aside. Next, insert your arm into the small gap and feel around for the actuator. Pull the actuator out of that small space carefully.

Tip: Use a borescope if you’re having trouble finding the active grille actuator.

Step #4: Replace The Old Actuator

Press the two tabs on both sides of the old actuator assembly to release the motor from its mount. Install the new actuator into the mount and secure it in place. Return the actuator assembly to its original position.

Step #5: Reassemble And Test

Return the parts you removed earlier and secure them. Once you reassemble your BMW’s active grille, turn on the car’s engine. Next, check if the active grille is now working as intended.

Take note that you may need to program the new BMW active grille actuator for the assembly to work. If you need to go through this extra step, watch this video if you need help in using the BMW ISTA+ program with a car diagnostic scanner to aid you in programming the module:

Ford Focus

Ford Focus models made from 2012 and beyond typically have active grille shutters. Unlike the active shutters in the BMW, Ford's grilles function differently. This assembly opens when the vehicle moves slowly. That way, the opening can let in additional air to help cool the engine.

Chevy Cruze

The Chevrolet Cruze’s active grille shutters work similarly when compared to the assembly in a Ford Focus. It also opens and closes depending on the sedan’s current speed. But Chevy's active grille may also open or close depending on the engine's current temperature.
