I'm not sure how the Mk 5 Ibiza's headlights are designed but a good trick to stop/slow this down is using a little silica gel pouch placed inside the headlight. It doesn't need to be placed specifically, just within the sealed area. I put one on the inside of the access cover of my Mk 4 and used a sticky pad to hold it there.
You usally get them in packaging for many things such as trainers, furniture, PC parts, etc... and their purpose there is to absorb moisture to maintain the product they're bundled with. See if you can dig one out from somwehere and pop it in.
It usually works a treat!
