My wife has a Volkswagen Polo S 1.2 64PS registered 06. The VW dealer has told her that she should have the cambelt changed as the car is 4 years old. But it has only done 30,000 miles and I thought the cambelt change was based on mileage rather than years. They will do it for the special price of £379 instead of £500. At the same time they told her the brake fluid should be changed – despite changing it in February this year (or at least charging for it) but that is another story that I will take up with them.
