Try removing the pads, open the bleeders and push the pistons all the way back. quite common for golf calipers to trap an air bubble behind the piston. Refit pads,close bleeders, pump pistons back out and rebleed. Not deffo but worth a try.

also make sure your bleed nipples are at the highest point if not undo the calipers and move them on the disc so the nipples are at the top it took me hours to work that problem on mine . are getting fluid out of the nipple

I have used a nissin 11/16" master cylinder to 2 Audi calipers. After bleeding the pedal felt a little spongy so I applied the brake with a heavy weight and left it overnight. In the morning the pedal was nice and firm.
