With option 552 "Adaptive LED headlight"
SITUATION
Condensation or fog forms inside the LED headlight lens cover
CAUSE
Water enters the headlight from the headlight ventilation filter.
PROCEDURE
Do not replace the headlight. Follow the modification procedure below to remove the ventilation filter:
1. Remove the trim on the side panel of the hood. Refer to ISTA Repair Instruction, "REP 51 76 035 Engine bonnet-seal bracket."
2. With a screw driver, remove the cap from the headlight as shown in picture.
3. To remove the headlight ventilation filter, use a 3 mm Allen wrench.
Note:
A pin from a plastic body rivet which is 3 mm in diameter will also work.
4. The Allen wrench or plastic body rivet pin should be 40 mm long (allowable clearance for the tool in the vehicle). Mark 25 mm of the 40 mm length with paint or something similar: this is the depth limit inside the ventilation filter hole in order to remove the filter.
5. Insert the 3 mm diameter pin or Allen wrench 25 mm into the hole, displacing the filter as shown in the photo. Repeat this process several times.
Note:
The filter remains inside the headlight, but is no longer needed.
6. Perform this procedure for the other side.
7. Reinstall the cap and cover for both sides.
8. Drive the vehicle or leave the headlight on for about half an hour, until the fog or condensation clears up.
