hi all, ive just started to fit my p-flo kit to my AUQ cupra, im no mechanic and have been looking forward to fitting this, trouble is ive just encountered a small problem when trying to remoe the MAF, it seems to be held in place by 2 'screws' but i have never seen a head like them before! they look like thay have five lugs within the head but then there is a central 'pin' which is is preventing me from removing them with the limited tools i have to hand. does anyone know what tool i need or indeed what these screw heads are called please? many thanks indeed.
