Plastic centrecap for the factory "Carat" style wheel, as fitted to various special edition and high spec models, and optional on others.
Please don't confuse these with the cheap aftermarket reproductions (that are often sold at a higher price!).
We've tried the cheaper ones, they're too tight and crack when fitted. For the price difference its not worth the saving (if any!)
We only sell the genuine ones for this reason. Always check with the supplier which they are as they are visibly similar... the cheaper ones dont have the VW Audi logo inside.
