The engine cover is the subject of a safety recall across all VAG brands. It’s recently been discussed on the
Cupra Formentor website.
Someone over on VWROC.com forum recently posted that a revised engine cover has now been produced - with revisions to the design of the attachment points. These are now made of a harder plastic than before, creating a tighter fit with the fixing points on the engine block, so eliminating (or significantly reducing) the risk of the cover coming loose.
I dare say it’ll take a while for the roll out of replacement covers and getting these fitted to owners‘ vehicles.
