use a T20 torx bit to take off the dash top; three across the top and one at either end.
You can now see two more torx bits holding in the main cluster. They are supposted to be bolted at the bottom aswell(i think) allthough mine whernt, if they are you need to remove the housing behind the steering wheel, one mor torx bit at the bottom in the middle, then two more once this is removed!
After all this the main cluster should be loose, you will only be able to move it a bit as the speedo cable is so short, but you should be able to reach behide and squeeze the cable at the base, it should now be ready to pull out.
There are about 5 or 6 electrical connection's that just pull out, dont worrie about whitch goes where cos they are all different (again i think)
Then visa-virsa
Please only use thease as a guide cos im not 100%
