Notes

• Compare 5DV 009 720-00 with the number on your original ballast before ordering. The label on this unit reads 5DV 009 720-00.
• Dry any moisture in the headlamp before fitting a new ballast.
• A like-for-like new ballast that matches the original part number is typically plug-and-play. Adaptive headlamps, or a used module, may still need coding or fault clearing if a warning remains.
• Professional fitting is recommended.
• Coding: like-for-like new ballast/driver replacements that match the OE part number are typically plug-and-play with no coding required. Always match the number on your original module. Adaptive/AFS headlight systems or used modules may still need coding, initialisation or fault clearing with diagnostic tools if warnings remain.
• Address any moisture ingress in the headlamp before installing the new ballast
• Professional installation is recommended for optimal performance
