Hi..there..

If it was high pitched squeeling noise thats changes with RPM or engine speed..then its probably quite likely the auxillary/fan belt is slipping or soemthing that belt runs is siezed up or or binding causing the belt to slip..open the bonnet and have an inspection down the drivers side of the engine and ensure the belt is still there..given that you have said the nosie suddenly stopped...you want to esnure the belt hasnt actually snapped or fallen off..if it has then your best either contacting your breakdown service either RAC,AA,GREENFLAG who ever your with to get it to garage and have the belt replaced or even maybe a decent mobile mechanic to check it out...
