Not entirely, I know very little about cars but I do believe it's belts, as when I had it serviced and I asked the bloke to check the belts for noise he suggested replacements. I know the air-con belt is squeaking as that squeak dissapears when I turn the A/C off. The other squeak is mainly at cold start and occasional driving noise I think maybe timing belt or something? How do you determine if the noise is bearings or belts?
