When i bought my audi a3 1.6 Se, 2 weeks later the fourth cyclinder went before i go on about how my window squeeks does anybody know what sort of problems i could look to expect in the near future as my car has just clocked over to 100.000

Anyways my driver side window squeeks any ideas wot i could do to stop it, it sooooooo annoying!
and last but not least in fact the most important mr N/S Strut seems to be knocking only once if i slow or speed up any ideas what this could be as i can get this done on warranty if i can identify the problem
