Engine Cooling problem
2003 BMW E46 6 cyl Two Wheel Drive Automatic 102000 miles

The car loses water when in motion eg if travelling at 70km/h the radiator alert will come on after a distance of about 8kms. Pressure testing was done and no problem detected. Radiator was flushed but problem still persisting. Splatters are evident on the inside of the fan closest to the radiator. When radiator alert came on, temperature gauge was just below the half-way mark, as always. Water not mixing with oil.
What could be the problem? Please help.

Replace the pressure cap.

Sounds like the lower hose wasn't changed, I'm surprised you can't follow the leak.

Check again later, maybe when you were refilling it you let alot of air in the system and after driving it finally settled.
