If you find a set of the rubber OEM ones many TDI's came with, they are great mats for winter....
Many dealers included a carpet set and the rubber ones as a way to up the purchase price, but honestly I was happy to have both in the end.. carpet fur summer, rubber for winter.
Skip the cheap Amazon carpet ones ..have bought a few different sets for different cars over the years, they are always garbage... barely 3 month/3000 mile trash.
Unless you send close to $100 like the weather-tec, OEM, etc, most mats are basically disposable decorations
