These arent as straightforward as they used to be.
When Leon2/Altea/Toledo3 were launched they all had the same basic blade which the refill fitted no problems.
Since then, SEAT have changed the factory and the replacement blades, more precisely how the rubber is fitted. That means now we cant know for sure if refills will fit.
Ok for us in the workshop as if it doesnt work, we stick on full blades - not so good for you at home with a handful of bits and no wipers
The refills are a genuine VAG part, but with no specific application
guide.
Worth bearing in mind . . . .
