I don't have step by step instructions, but I don't find the job all that hard. It would be a lot easier if you had someone show you how to do it rather then explain it. Once you have the cluster removed from the car there are so torxe bit screws on the back that you undo and the plastic clear front comes off. Then you are able to remove the needles by pulling them straight up. The tricky part is lining the needles back up where they should be. There is a check feature on the computer that you can use if you plug the cluster back into the car that will move all the needles to the middle so that you can align them.
As i said it would be alot easier to have someone show you. and depends if your good at this kind of thing
As said above there r no torx bits 2 just get at the dial facia. unclip plastic cover and the black cover surround u'll find it easier 2 get the lot off if u do them 2gether. Use a fork that doesnt have sharp edges on it and use that like a pair of pincers.
Being a VX u have the option 2 use the hidden menu on the trip computer 2 check ur needles alignment. fuel and temp gauges should b on half way, the tacho on 3000 RPM and the speedo at 100KMs.
