My Passat sport has recently started to loose water. I have to top up system with a pint of water every 2 weeks. The oil in the engine looks fine so no leakage into engine. Any idea's of the cause and where I can look to identify and correct fault ?? Very much appreciated.

Radiator, a hose, water pump or heater matrix. Look for pools of water under the car after you've parked for a while. That should give you a clue where it is leaking.
