Car screeching at startup Sign In

I have a 2006 BMW 325i - over the past month the car has begun to screech/squeal for the first 3-5 minutes after start up. The screeching is worse with acceleration and making turns. It only occurs for the first few minutes of the FIRST drive of the day - subsequent driving for the day does not have screeching - the noise only occurs when the car has been sitting around overnight or longer. Any thoughts?
Thanks!

I'd check the tension of the belt. If it is loose and the squeel was it slipping you might consider a new one as it could have some damage,

You would call it a fan belt but the car probably has electric fans. Most belts are serpentine and self adjusted by a spring loaded tensioner pulley. Again most cars use just one belt but I can't be sure of all cars out there. A quick look will tell and with engine off and cool, you can just feel that the belt isn't tight enough if so,
