Hi there!
I have just bought a Nissan Almera 1.8 from 2004 manual transmission.
One thing i have noticed, is that it makes a slight whining sound that will pitch up with the engine speed
and then the whining sound will disappear when the engine speed increasing
I have recorded the noise with my phone https://instaud.io/1RR6 What could it be?
All the best
Patrick
