1.8. Attach service cover with desiccant pack to headlamp
1.9. Install lamp unit
.
.
2. If no reduction in the degree of fogging is visible, the lamp unit is defective and must be replaced.
On the new lamp unit, the service cover with desiccant pack must be installed.
Note: Residual fogging is possible due to the laws of physics and is OK.
Fogging does not impair the functionality or the service life of the lamp unit. .
Desiccant packs must always be used in both lamp units.
To ensure that the drying pack (absorption) acts effectively, the headlamp has to be air-sealed.
Observe or check the following points for this:
1. The seals on the central connector must all be present [Picture 5 (1)] and correctly fitted [Picture 5 (2)].
2. The new transparent diaphragm must be correctly bonded [Picture 6].
3. Check headlamp housing for any external damage.
