Notes for replacing the protective cap of the headlight (4' Series Coupe/Convertible, 4' Series Gran Coupe Sedan)

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!
