My Octavia Elegance 2.0 TDI is a couple of months old. Last week the coolant warning light came on, preceded by three beeps. The coolant level was ok but the warning light was flashing constantly. I took the car into my Skoda dealer a few days later and they changed the coolant header tank. Everything was fine for three days and then this morning the warning light started flashing again. I've arranged to take the car back to the dealership again next week, but this is a bit annoying. Has anyone experienced similar problems?

I had this on my Bora and it was just a slightly faulty loom connector. The one that connects to the sensor on the header.
