HI guys.. before forum police say that I should have searched.. I have for 3days, read every post on relevant posts, tried other forums from other websites (but prefer audi-sport ) and still I am sooo confused... So I have a 55 plate a3 sportback with MFSW and want to remove the wheel.. I have all the torx bits but am concerned that I dont have the correct tool to remove the centre nut. Some say its a M12 spline..... some say M18 spline... I have even heard its a T55 socket....fairy dust....not very good with tools but I know M is for Metric so M12 and M18 are definitely different. So basically... what tool will I need to remove the centre bolt to get the steering wheel off? Thanks PS before you try and link me to a thread... I have probably already read it ... but as I said... I have read so many different things to do the same job.. hope this clears things up for people in the future too . Thanks.
