if its the front one thats metal(that im thinking of) its actually pretty easy just gota take off the front part of the wheel liner on both sides and zip the 2 side bolts(on each side) and the 3 or 4 on the front of it. i believe they are 15mm. iv had to drop one side of it on my 14 a couple of times for random reasons. the bolts for the wheel liner are either a 5.5mm or 7mm i believe there is 2 or 3 of them on the underside before it goes up the wheel arch. can then pull it down enough to fit either an impact or a ratchet in. the plates bolts may be abit rusty depending on where you live so penetrant may be your best friend on that.
