Heater matrix leaking.

Check your coolant level, if heater matrix is leaking then your coolant level will gradually drop.

Otherwise it could be fumes from a leak somewhere in the exhaust system or possibly fumes leaking from a leaky injector seal (assuming you have a diesel model). I would have thought you'd be able to smell if it was exhaust fumes though.

found out it was the internal radiator lads. 8 and a halfhour job but got it fixed anyway _

Glad it's done. I often see ones where just the O-rings between the plastic parts have turned brittle and cracked with age and heat. Means they steam for a long time before they start dribbling visibly. If you were tight you could probably replace them and add a smear of Silastic.
