# Service bulletin LI82.10\-P\-078302 A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned. - Type: Service bulletin - NHTSA id: 11008323 - Published by NHTSA: 2024\-10\-03 - Manufacturer's number: LI82.10\-P\-078302 - Manufacturer's date: 2024\-09\-10 - NHTSA component: EXTERIOR LIGHTING ## NHTSA's summary Complaint Headlamps fogged or droplets forming. Cause Due to its outlet openings, the headlamp is an "open system". This means that acidic gases, moisture, dirt and exhaust gases can penetrate into the headlamp. This can lead to the formation of condensation on the lens of the headlamp. The headlamps comply with all applicable US standards and regulations. Remedy Check housing cover of lamp unit for natural fogging or condensation as per LI82.10\-P\-078301. If a reduction in the degree of fogging is visible, the desiccant packs can be used once the condensation has completely evaporated. Note: Order service covers and desiccant packs based on the validity description. 1. Remove headlamps. 2. Remove all grommets from outlet openings. 3. Seal vent openings with sealing profile. Important: All openings must be sealed carefully for the pressure compensation diaphragm to work properly\! 4. Remove existing service cover. 5. Place desiccant packs into the new service covers and bolt down \(Picture\_01\). 6. Glue the new diaphragm onto the intended surface at the service cover \(Picture\_02\). Note: The bonding surface must be clean and dry. 7. Attach service cover with desiccant pack at headlamp. 8. Install headlamp. To ensure that the desiccant pack \(absorption\) acts effectively, the headlamp has to be air\-sealed. Observe or check the following points for this: 1. Seals at the central connector must all be present and correctly fitted \(Picture\_03\). 2. The new transparent diaphragm must be correctly bonded \(Picture\_04\). 3. Check headlamp housing for any external damage. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2024/MC-11008323-0001.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2024/MC-11008323-9999.pdf) The document is the manufacturer's.
