Hi,
Its a easy job to get the instrument pack out, i have just done mine to change a bulb.
If you take the panel off the bottom of the lower dash. held with 4 screws hidden under blanking caps. this will reveal 2 screws to the left and right of the stearing collum which hold the dash finisher (the piece with the fuel flap release button in) then remove the 2 screws in the top. that will allow you to lift this out, you will have to unplug the multi plug to the fuel flap release.
There are 2 multi plugs on the instrument pack you will see them as soon as the dash trim is removed
If you want to remove the instrument pack. this is held in with 4 screws 2 on the bottom and 2 on the top.
Thats it as easy as that..
Hope this helps
Bryan
