First please update your vehicle (year?: 1996-2016, model?: 32, 200, 230, 250, 280, 300,320,350,55) in your profile as it helps the members answer your questions which usually are based on that information if you haven’t.
Follow exactly to update: ‘Usercp’ at the top of page, then ‘edit your details’ on the left side, ‘additional information’ near the bottom, edit your ‘vehicle’. Info in your garage does not update your profile.
