Hi guys,

A reputable mechanic shop has replaced all the fluid for my car (transfer case, ACD, engine oil, gearbox oil etc) about 3 weeks ago and I started experiencing the whining noise from the engine in the last few days.

The whining noise is from the passenger side (battery side, as my car is RHD) and I am not quite sure where it is really from.

-It only happens when I drive the car (normal daily driving, not spirit driving)
-Whining noise disappear when I come to a stop or sitting at idle
-Does not happen on cold start. When I start the car in the morning, the noise will come after the car is fully warmed up (after 10,15 minutes driving).
-It is really noisy and I feel like the engine is just about to explode

Things I have changed before the whining noise issue:
-Changed all the fluid
-Changed to a new K&N POD filter (my old Pod filter is dirty and damage)
-Installed a new alarm system

This is my DD car and the whining noise is like a ticking bomb waiting to explode.

I have attached a sound clip in this post. Can anyone give me some hope to find out how to fix this issue?

Thank you for your help
