Please check notes in each part listing to ensure the Diagnostic Test Connector is correct for your 2007 BMW 525XI with a 3.0L engine. Special restrictions like "California only" or "with sport package" may indicate a Diagnostic Test Connector fits only certain 2007 BMW 525XI models.
Clicking a "More Info" link will display a picture and/or other details about that Diagnostic Test Connector in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Diagnostic Test Connector, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Electrical-Connector parts, other BMW 525XI parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 2007 BMW will not be lost if you switch.
