Hi all,
have noticed when wife starts 130PD Tdi from cold the engine has an extra noise which is coming from around belt area and sounds almost like a belt is gently rubbing on something until engine is warm and all goes quiet.i am wondering if this has something to do with the viscous fan and would just like to know if this is normal or not-cant remember hearing it before but then again was i listening?!

best regards,
mike
