These are a common fault for coming apart on Titanium models.... They are also ludicrously expensive!!! You'll need a new boot badge too probably. Fortunately after 7 months of waiting I grabbed a deal on one for £130 genuine Ford. The copy ones are terrible so don't be drawn to buying one of those
The price of this is ridiculous, but the quality is at least good. It comes with a gasket, so you don’t need to buy one separately. Note that it’s difficult to prise old Ford badges from old trims, so you might need to buy one as well.
