Reason for change
Reason for block
Complaint:
Lamp unit fogged or droplets forming.
Cause:
Due to the vent openings, the lamp unit is an "open system".
This means that acidic gases, moisture, dirt and exhaust gases can penetrate it.
This can result in deposits on the diffuser and lens.
Remedy:
Check housing cover of lamp unit for natural fogging or dew as per GI82.10-P-009047.
.
1.
If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has
completely evaporated.
1.1. Order the required service covers by referring to the variant overview.
1.2. Remove lamp unit
1.3. Remove all grommets from vent openings.
1.4. Seal vent openings with sealing profile.
Important: All openings must be sealed carefully for the pressure compensation membrane to work properly!
1.5. Remove existing service cover
1.6. Place desiccant packs in new service covers and bolt down
1.7. Stick new membrane onto surface provided on service cover
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 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. .
