Condensation in the headlamp
If the above-mentioned vehicle is found to have an extreme amount of condensation forming in the headlamps, the cause might be water entering through the ventilation hose.
In order to combat this, the vehicle manufacturer offers a modified hose, (Fig.1 / Fig.2), which is intended to reduce the high level of condensation. Another feature of this hose is that its shape governs the mounting position.
Parts no.: ventilation hose
