If it's squealing on start up then you will need to change the aux belt and tensioner. Straightforward DIY.
 
Have the belts been changed? Still sounds like the dipstick to me! Or oil cap as Legend@wheels also suggested. Would still try unplugged/replugging those again first.
 
If you hear it only in cold start then its not what i mentioned( what i said you would hear always.) check when last time belts changed
 
the belts were changed early at about 30,000 and its now on 65,000 so its a possibility it could use a aux belt, getting it in for a ball joint next week so will ask the garage to have a look! thanks for your help guys

More than likely, they may not have changed the aux belt with the cam belt.
