Hi just got a C5 VTR+ 2.0 hdi16 2009 its a awesome car lovely ride as always with a used car it has a few faults I will be getting fixed under warranty but when I picked it bought it ,it had a noisy aux belt and I asked for that to be fixed before I collected it when I collected it they said the belt was dried out so they siliconed it sounded daft but it didn't make the noise any more so I took it ive had the car for about a week and the noise is back its not like a slipping belt more a rise and fall noise. just wondering if there is any known isuses or any thing expensive I should be looking to get fixed before the end of the warranty. regards stuart
