Feck me. I know you like the car but 3 litres of oil is bad. I would be going back to the garage to find out if they can at the very least pay for a service, but three litres has been driven for 3000 miles with low oil. Thats potentially fatal for this engine.
As for the ECU. It must be a different sound to mine. I can faintly hear mine when i switch the engine on behind the heater controls.
