Car into the garage today for a 2nd opinion on where the f my clutch fluid is running off to, and of course on the same day I now have my front windscreen almost opaque with condensation for the whole 40 minute journey to work, the only thing that would stop it steaming up would be the air-con for a few minutes but it would rapidly return after switching off.

I have a de-humidifier pillow in the car, it's not from wet feet etc.
No boot leak issues,
No leaves/debris clogging up front end blocking airways

Heater Core/Coolant leak?

Or even better it's actually my clutch fluid? 😆

There was a smell initially when I turned air con off the first time but I wouldn't say it was sickly sweet, more like hints of my decat exhaust fumes

Any advice/healthy donations appreciated

"Heater Core/Coolant leak?" - Are you losing coolant?

"There was a smell initially" - Check the condition of the cabin air filter.
