Im losing water from your Skoda octavia 19 tdi but dont know were from as you cant see it leaking and the oil is free from water?

If you're losing water from your Skoda Octavia 1.9 TDI but can't see any leaks, it could be due to a few potential issues. Check the coolant reservoir for cracks, and inspect the radiator and hoses for hidden leaks or signs of wear. Additionally, the water may be evaporating if there's a small leak in the cooling system, or it could be a head gasket issue allowing coolant to enter the combustion chamber, which might not mix with the oil. It's advisable to have a mechanic perform a pressure test to identify the source of the leak.
