This is my first post on here as a new member so be gentle lol ;-) My mrs has a mk2 galaxy 1.9 tdi ghia on a 51 plate, She has a loss of water but no signs of head gasket failure. Car has to be topped up before most journeys and it only seems to lose water when vehicle is being used. Im guessing at water pump leaking but have looked underneath and can't see any leaks while car is running or not running. Any ideas where to look? Thanks
