Morning all, My 159 2.0JTDM ti has developed a very strange screeching noise?
When the car is cold its not present.....I have a 30 mile commute to work, and driving to the motorway and down the motorway the car is fine, I then have a 5 mile journey once off the motorway and this is when the noise becomes apparent, it seems to be at around the 30-40mph area when the car is decelerating or freewheeling, if I push the throttle and speed up the noise tends to disappear, its quite loud, especially if you wind the window down.
The car appears to be running beautifully apart from this weird noise that started yesterday, its got 68k on clock and hasn't had water pump or cam belt done as yet as a bit of backround info.
Could it be brake related? belt related? vacuum leak as i've just seen on google?
Hoping this is a fairly common issue and an easy fix? going to take it to a local garage tomorrow if I can
