Technical Service Bulletin • There is considerable moisture present in the headlamp (Figure 1). • The moisture disappears only after extended drives (greater than 10 minutes). • There is no external damage to the headlamp which could introduce moisture. Figure 1. Moisture in headlamp. Technical Background Humid air settles on the inside of the glass, causing moisture to appear on the inside of the headlamp lens. Because of the headlamp circulation system, outside air is allowed to flow through the headlamps. The open, water-protected ventilation system (needed for pressure compensation) creates different “climate zones” inside the headlamp, where the lens is either warmed up by the light or cooled down by passing air. When high air humidity and temperature differences exist between the inside of the headlamps and the outside, condensation can form on the inside of the lens, especially in cold and wet weather. This moisture buildup can happen, for example, after a car wash, after steam cleaning of the engine or the front end, or after overnight temperature changes. This condition is more easily visible with headlamps made from clear glass. The moisture is an optical condition which does not affect the headlamp function (light performance) and does not lead to corrosion or damage of the internal headlamp parts. This condition is common to all exterior vehicle lights, and can occur on every headlamp, fog lamp, or rear lamp. Production Solution • Optimized headlamp ventilation hose placed into production for all xenon headlamps. • Charge air ducts placed behind intercoolers. Service 1. Remove the headlamps and dry the inside using compressed air or a hot air blower. Check for any loose caps, loose or unsealed control modules, or cracks in the headlamp housing(s) as the source of moisture exposure. 2. Vehicles prior to VIN # *CD004736 were not built with the updated ventilation hoses. If the updated © 2014 Audi of America, Inc. Page 2 of 9 All rights reserved.

Technical Service Bulletin ventilation hoses are not currently installed, replace the headlamp ventilation hose for each headlamp with the new part number to help reduce any further humidity ingress into the headlamps (see Required Parts and Tools, below). Proceed to step 3. Tip: The updated ventilation hose can be recognized by the integrated filter (Figure 2, arrow). Figure 2. Updated ventilation hose with integrated filter. Tip: The updated ventilation hose is not connected directly to the headlamp housing. The hose routes downward from the headlamp carrier and between the radiator and bumper (Figure 3, arrow).

Technical Service Bulletin 3. Each headlamp air ventilation tube must be sealed to protect against further moisture ingress (Figure 4). Figure 4. Headlamp ventilation guide tube. 4. Install ring seal on headlamp air ventilation tube (Figure 5). The larger diameter of the seal faces the headlamp. Figure 5. Ring seal installed on headlamp air tube. 5. Reinstall headlamps. Tip: If the headlamps were removed after butyl cord or other rubber type of sealant was already applied to air tubes from a prior procedure, remove the old sealant before installing headlamps. 6. Check vehicle for left and right air ducting for exiting air behind charge coolers (3.0 TDI air-air heat exchange) or additional water radiators for charge air cooling (3.0 TFSI water-air heat exchange). Vehicles built from June 2010 will not have these exit air ducts installed. Check vehicle regardless of build date. If air ducts are not installed, continue with steps 7 – 11. Otherwise, proceed to step 12. © 2014 Audi of America, Inc. Page 4 of 9 All rights reserved.

Technical Service Bulletin 7. Remove front wheels and wheel housing liners. The rear of the charge air coolers or additional radiators will be exposed (Figure 6). Figure 6. View of additional radiator with wheel well liner removed. 8. Locate exit air duct attachment hooks on the left and right charge air coolers or additional radiators (Figures 7 and 8). Figure 7.

Technical Service Bulletin 10. Inspect exit air duct attachment points to be sure that ducts are engaged properly over hooks (Figure 10). Figure 10. View of exit air duct affixed to mounting hook. 11. Reinstall wheel well liners and wheels. 12. Inform the customer that the new ventilation hoses and sealant are only to help reduce the moisture condition, and will not eliminate the condition completely. Moisture in the headlamp lens is normal and can occur even with the improved filtration and ducting. Vehicle may need to be driven at sufficient highway speeds to help aid in clearing out headlamps. © 2014 Audi of America, Inc. Page 7 of 9 All rights reserved.
