The door check keeps the door on your X3 from opening too far and allows the door to hold an open position. When door checks begin to fail, the door will no longer stay open and tends to close on you when you release it while entering or exiting the vehicle. The welded mounting nut (in the door jamb) can also fail, leaving the door check improperly mounted. If this happens, you will need to visit a body shop to have a new nut installed. If you have a clicking sound when open and closing your door, inspect the fasteners at the door side of the door check. The nuts are mounted in plastic and can break free, causing a loose connection and noise.

The first step in replacing the door check is removal of the door trim panel. This is necessary in order to gain access to it. You need to disconnect the battery before working on the panel. See our tech article on door panel removal.

Remember that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve as they grow older. If something seems different, let us know and share your info to help other users.

This tech article will show you how to replace the door check on BMW X3 models.

The door check (red arrow) and rubber seal are both available as replacement parts, as well as the fasteners.

The door check (red arrow) and rubber seal are both available as replacement parts, as well as the fasteners. The original fasteners are microencapsulated, meaning supplied with theadlocker pre-applied. If reusing the fasteners, be sure to apply Loctite on the fasteners.

Support the door in the open position.

Then remove the door check through the door cavity (red arrow). Reverse the steps to install the new door check. To inspect the condition of the welded nut, I threaded in the E10 bolt, then tried to press it in. If the nut is secure, it shouldn't move.
