Hello all , my first time here, prompted by a very small coolant leak on my 53 plate fabia 1.4, cant seem to find where its coming from , can any of you guys point me in a possible direction, all hoses and expansion tank seem dry?

Welcome!

Head gasket? What's happening to oil level, is it increasing? White gunk under the oil filler cap is generally a bad sign (although this could be caused by lots of short trips).

Hopefully just a leak which you haven't found yet. Good luck!
