I'm new to posting on here, but I've been reading the forum for a while. I have just purchased a 3 month old a3 2.0tdi s-line in red, with DSG, which Crewe Audi's demo. I picked it up on Thursday, and on Saturday contacted the dealer to report a noise coming from the front passenger side of the car. They booked the car in for Monday, spent the day test driving it, and drinking my diesel. I picked the car up yesterday eveing, to be told that it needed a new gearbox, as it was making a noise from the Diff. I'm not really an expert on gearboxes, but surely they shouldn't go after 7k miles. I'm just concerned that I'm on a slippery slope here. Has anyone got any experience of this? Can anyone assure me that this will not happen again once it's been replaced? Do I have grounds for rejection, or any kind of compensation? Apart from this, the car is amazing! Any comments greatly appreciated. Thanks, and sorry for the long post! P.S. The car is also in to have some scratch's removed, that appeared in the time that I 1st looked at the car, and picked it up, so my faith in this dealership isn't amazing at the moment.
