Vehicle Compatibility

Please compare part number 8V0907399D and all electrical connections with the original module fitted to the vehicle before purchasing. Similar-looking headlight modules may not be interchangeable.

Coding and Programming Requirements

Coding or adaptation may be required after installation. A compatible like-for-like replacement with the same part number may operate without additional coding in some vehicles, but this cannot be guaranteed.

Professional installation is recommended. The vehicle should be diagnostically scanned before and after replacement to confirm the original fault and ensure the headlight system is operating correctly.

Please confirm compatibility and installation requirements with a Volkswagen lighting or automotive electronics specialist before ordering.
