Replaced my Ateca blades myself, the ones fitted at the factory are rubbish, never had wiper blades that make so much chattering noise as they scrape over both windscreens!.
Fitted a cheap set of replacement rubbers off Ebay and hey presto, no noise!.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
