G'day from down under again.
Just lately, I've been aware of a rhythmic squeaking noise, which I think is coming somewhere from the transmission.
It's only just audible over the exhaust noise. It has a frequency of a few Hz that correlates with engine speed and gear. Accelerate and Hz increases. Up a gear and the Hz reduces. No noise when in N or stationary.
I initially though it was a squeaky wheel noise but popping it into N while in motion caused the squeak to disappear instantly and returns when reengaging a gear.
It only occurs after cold start and always gradually fades away completely within five minutes of driving.
Hard to localise the noise because it's only present when driving.
Any thoughts what it could be and whether it's of any concern?
Thanks.
John
