Steering Noise on Cold Start Options

[rasta]

Hi

Recently I have been hearing a noise from my car when its started up on cold. The temperature in England is about 2 Degree Centegrade recently. It goes away after the car gets warmed up.

The car seems to related to the power steering. The sound changes when the wheel is turned slightly. It is quite loud sounding like a long chirp.

Apart from this there is no other unexpected noises. It doesnt seem to be the engine as it seems fine when i rev it and its not linked to the noise.

Anyone able to potentialy diagnose this?

Much appreciated,

Thanks

oh ok, thanks,

is that checked in a major service? its due for one this week.

if its loose, then how come the sound goes away after 20 minutes once the car is warmed up.

Also what are the implications if it snaps? is it as serious a cambelt snapping?
