One more problem I discovered on my new used 147 today, is condensation. Today we had a rainy day and a big temperature drop (I'm in Greece, weather much more dry and mild compared to the UK), and tonight I noticed heavy condensation on both headlights. Especially on the smallest lights area (don't know the proper name in english).
I will try the silica gel and lubricating the seal suggestion, but since I also have to polish the headlights because they are foggy, I would like to be sure that the headlights are actually usable before spending money and time on them.
First of all, the electronic adjustment motors are dead and disconnected.
The previous owner has put some ****ty xenon lights, on the medium light position. The the big and small lights are still regular. Nothing looks changed on the headlight. Are those xenon kits regular size/type lamps that use different power, on the same headlight casing? Is there a case they drilled something in order to fit the xenon kit? Is the xenon light so hot it might have melted something in the headlight?
