Hi all, my Fabia Monte Carlo drivers headlight is regularly suffering with condensation and has got significantly worse over the past few months. I realise that the weather and temperature make all the difference and in the sunlight it does dry out eventually. However, the condensation quickly returns most days. I've used Google and YouTube and seen various articles and videos and suspect it may be a blocked air vent that is causing the issue as I can't see any leaks or chips to the actual headlight unit and there isn't any water build up inside. Whilst all the articles are useful in identifying the issue, I haven't found one that actually pinpoints where the air vents are located on the drivers side headlight. There isn't a great deal of room between the back of the unit and the rest of the engine bay and so has anyone got any photos or diagrams that will help me please? Many thanks.

Did you have any luck solving this.  My parents are having the same problem on their fabia

No joy, I'm afraid. I did however speak to my mechanic and he has suggested that this won't be an MOT failure as long as I put the headlight on high beam and dry out the casing immediately before I take it for it's yearly test. The MOT was my only fear as I've got the Monte Carlo model and the headlight is the black rather than chrome version. Sourcing a replacement is a nightmare and they only seem to be available from Lithuania and cost around £400 and that's before paying to have it fitted. 🙈

Still having issues with condensation in the headlight and so whilst I have identified where the large rubber breather covers are on the headlight, there are also supposed to be one or two elbow shaped rubber breather pipes/valves on the rear of the headlight that may need cleaning out. Does anyone know where these are and can perhaps show them on a photo or diagram please ? I've asked Claude AI and ChatGPT but neither of them can provide photographic help. Thanks all.

I had similar with the passenger side headlight on my daughter's Citigo and after a close look the only thing I could spot was that run off from the bonnet dripped between it and the wing directly onto the indicator bulb holder. So I took that out and used some silicon grease on its rubber seal, put some strategically placed duct tape over the top of it to the inner wing to redirect drips away from it and also ran a length of PTFE electrical tape over the top of the headlight where the glass meets the plastic body of the light unit. It's been dry with no condensation since.

I'm not sure if the Fabia might be similar but it's probably worth a look / try?
