Can anyone tell me how to remove the rear hubs on a Y reg fabia? I cant see how the 'plug' which covers the retaining nut is supposed to come off. It doesn't look like theres anything to get a good grip on with which I can pull it off. For example the caps on my ford fierce-star are simply prized off with a screwdriver, the fabia's ones look more substantial.

Also, does anyone have the pinouts for the lambda sensor? i'm trying to figure out if its still working or not.

Cheers, Dave.

Knock the cap off with a chisel.
