Make sure it`s not A/C condensate. If it`s HBV, coolant should be dripping off bottom of gearbox where it mates to engine block

well i did look for 5 mins and didnt see anything dripping. if it was the hbv would it be flooding out?

Depends. Mine last leaked with the a/c on, but was OK-ish with the a/C off, all depends where the diaphragm is split & what heat settings are set.  :y

thanks for all your help chaps. ill be honest i have no idea if its aircon water or this hbv fluid.

ive properly brimmed it and the dash warning has gone; im going to keep my eye on it but if it comes back suddenly is there a mechanic on OOF that could take a look (near northampton)?????? (obviously ill pay  :y :y :y :y

Air con does have a condensate drain to the floor but this isn't anything to do with this water loss.
There's a diaphragm inside the HBV which operates a valve inside which diverts coolant around your heater matrix or not. Depending where the split is in the diaphragm, and the requirements of the car for heat inside the car depends whether the HBV leaks or not.  :y :y

Does the "leaked water" taste of water or antifreeze?  ;) ;D ;D
