Bought my first car a couple weeks back, 6R 2011 1.2 70 SE, I've had the timing chain and belt change, but im still unsure whether the engine sound is normal. It'd be great if anyone could let me know if the sounds its making are normal.

Bit of a whistle when you let off the accelerator.

Thanks for taking a look
