I've always taken the line that I should try to source the same wipers as fitted at factory, with the Polo of the same age as your
Ibiza, they were all fitted with Bosch wipers on the front, so buying Bosch - maybe at Halfords worked out okay until I had enough time to buy genuine VW ones at a good price via eBay!
Even when I had a VW Passat 4Motion, I bought from VW - but not their "fit-all-looky-liky" Quantum branded rubbish, but got the parts dept to order in the correct part as had been fitted at factory - then some time later started looking on eBay for genuine VW ones at a good price.
I seem to remember buying Bosch front wipers for my daughter's late 2009
Ibiza - but that was forced on me as I discovered that they had got damaged (probably by her) in winter, though these also worked very well.
Maybe check what ECP sell as SEAT might also have used Valeo at the time your car was built.
One crazy thing that I found out about buying the VW Passat front wipers from dealer, VW seemed to be only supplying wiper blades for LHD cars, so the mounting clips needed to be reversed, not smart VW!
Edit:- when my daughter bought a
MK3 Ibiza 6K, from a SEAT dealer approved, it had completely wrong front wipers and one wrong front disc! Quality checks, AC usual rubbish!
