I bought a brand new car 6 months ago. On Monday, the diesel particulate filter light went on (has happened before) and I took it on the motorway to get rid of the light. However, it did not disappear. I took it to VW (it was due its first service aswell) and they have told me that the filter needs replacing. They also said it is not covered under the warranty and will cost £1700!!! Grrr. Im wondering if anyone knows what I can do to avoid paying this ridiculous amount of money. Any help will be appreciated. Thanks guys.
