Grinding/ Purring noise from front end

Hello,

So essentially my 1.4 TDi 2008 Polo, has started showing a considerable (bad sounding) what I think is engine noise.
The noise first was noticed on a cold start, there after the sound is only noticable in all gears when the revs drop down to around 1100 PM (200 above idle). The Oil has been flushed and changed as I thought it could be bad oil suffering in the cold conditions. Importantly when the car achieves a decent temperature the sound is no longer noticable even in the rev range.
I am doubting its is related to the clutch as I can press and depress the clutch when idling with none of the sound being present. Only when the car is under load at low rpm is when I can hear it.
Any suggestions of what too look out for on this type of issue?
