BMW 7 Series: Headlight Fogging Fault Pattern

NOTE: Certain weather conditions can lead to fogging on the inside of the headlight lens.

This is not necessarily a fault that requires replacement of the headlight.

1. Permissible fogging. Headlight does not need to be replaced.
2. Impermissible fogging. Replace the headlight.

NOTES FOR REPLACING THE PROTECTIVE CAP OF THE HEADLIGHT

IMPORTANT: Risk of damage! Damaged seals on the protective caps will lead to moisture penetration into the headlight.

This will in turn cause porous cable insulations and malfunctioning of the headlight.

When working on the headlight system, check the protective cap seals.

Replace the protective cap in the event of damage! Example: screwed protective cap.

Seal (1) on protective cap (2).
