Hi all I am having issues trying to find the correct part number for drivers offside (rhd) front Brake disc cover (splash guard) I have a 2012 b180 with the Sports pack with the bigger 295mm brake discs.. I have just had new Brembo discs and pads fitted but the mechanic that did them showed me where the old one had rusted through and was basically flapping around and rubbing against the disc so he had to rip it off. So I now need to find a replacement in the UK can anyone help.
