Hi, I'm trying to take the front bumper off my 2011 A3 8P Sportback and I've read all the different instruction threads saying remove all the Torx screws and the 2x 10mm bolts that are accessed by peeling the wheel arch lining back. I have 2 more fixings which are not mentioned in any thread. They are really awkward to get to and I have managed to take a blurry photo in which they look like more Torx bolts. I've tried different sizes, T30 and T27, but I can't get enough purchase on them to shift them. I was just wondering if anyone knew what they are so I'm not wasting my time with the wrong tool. Thanks in advance.
