Hi all. 

 

Got a new noise started a few days back. When the car is being used and it’s warming up I get a “pop” sort of noise. I recorded it this morning. It only does it once. Oil temp was 58, water temp had just hit normal and air con was on 22c. Had been driving for 15 minutes according to the dash. I’ve put a link to the video. It’s all dark as it was half 5 this morning. But it happens around 9-10 seconds in. 

 

Any my thoughts please. Could it be thermostat?
