i have a 1.3 diesel 2013 and Iím having a bit of trouble with the engine. First of all once itís driving for about 10 minutes, sometimes longer/sooner the noise off the engine changes completely. It turns into a more rough noise and when going up the revs thereís like a squeal noise, when this is happening itís drinks the fuel.. once I turn the engine off the cooling fans will come on for around 5 minutes then power down, took it to a mechanic and he said it was the temperature control sensor and replaced it. That helped for maybe about a week but the noise returned. Hasnít been using any more coolant than usual.
