So far no good.
The dealer has had the car since 4.45pm last night and just called to say they can't find anything for items 1, 2 or 4.

For item 3 they are going to try new window seals to see if that works.
I must admit item 4 hapens when the radio has been on for some time but does it all the time when it starts.
1, Loud whining noise from the Fan Belt Pulleys
2, Knocking rear suspension when cold and mainly when reversing
3, Front windows rattle when open a couple of inches, irritating clicking noise
4, Popping noise from the speakers when the radio, cd or ipod is playing. Sounds like interference, static, or loose connections.
