I have bought cruise control from VAG parts and am planning on fitting it this weekend. I have found some really good guides on this forum, and others, but want to try and buy the tool in advance for removing the main bolt from the steering wheel. All i know is that it is a spline torx bit, and that its 22mm, but these are numbered in T** numbers etc and dont know what number this one is. Has anyone removed the sterring wheel before, and does anyone know what size tool i need?

Thanks in advance.
