If heavy fogging or, in some cases, increased water ingress is observed inside the headlamp, this may be caused by a crack in the housing of the SML (side marker lamp) (Fig. 1).
The SML is partially covered by the CW seal.
(Figure 2)
Cause:
The housing of the SML is damaged.
Cracks may have formed by adverse mechanical stress, for example, if pressure forces occur in this area due to objects or tools: (closing the bonnet without removing tools / objects before).
- Incorrect adjustment of the bonnet.
