My headlights both steam up. Plenty of condensation,this happened after fitting xenons,took lights out cleaned them,removed seals and cleaned and put back,still the same.Where are the vents? i cant seem to find any,these are self venting 2002 A4 B6
 
When did you clean them? Your other post on this was only a day ago & in this weather they're not likely to dry out quickly if they breathing again! I dont suppose when you did the xenon conversion you got out the mastic sealant did you? This will cause air-tightness and hence fogging up. If you've still got the problem suggest a 2-3mm drill hole in both bottom corners of the headlight unit at the back to give you some air flow.
 
didnt use any sealant,but id love to know where exactly the vents are.
