Mine have vanished, and the pads are rattling. When I changed the pads the new springs didn't seem to fit well, and clearly they didn't. I spent an hour today trying to fit new ones, the same Ferodo FBA526 as the pair that have gone missing. I've checked and they are listed as correct, but ain't. There is no way they will stay in place more than momentarily - the loops that sit on the carrier projections are round, not squared off like others seem to be, also the dimensions don't seem quite right. So the question is: has there been more than one type of OE ATE caliper used on the 2008 Sport Q2 1.9 16v JTDM 284mm brakes?
