As some may have noticed, my wiper of the right headlight system is defective. So what do you do on Sunday in nice weather? Right you squat in the garage and screw thanks to the support of pseudoR and lucky017 who have explained to me via PN what to do, the thing is dismantled. At the second glance something beautiful bright green discovered, to this a treacherous “hissing”. Here are the pictures. Questions: 1) Risk of damage to the climate? Should turn off if too How long is the leak already unknown 2)Can I drive like this, or do I fly away any things? There are still bags over the connections of the Neblers. 4)Are there typical things in the climate Volvo, or can this also a free workshop? 5) Anything I don’t think about? To explain. The leak is on the black pipe that goes from above into the silver box. From the connection in the silver box it hisses. I have provisional with K abelbindern fixed (obviously no hissing anymore) – will hold to the next pothole
