Dash top off. Pull back the seal on the inner part of the door towards the front. Remove the 2 trims running alongside the A posts. Open both doors, remove a Clip facing outwards - little black thing. If the doors where shut, you'd be unable to see it.
Remove the cowling around the steering wheel - 3 T20's where your knees are but you can just take the top bit off. Remove the trim above the glove box, remove all screws behind it. Same where the key goes on the drivers side. Remove screws/trims where your speedo is.
Then Lift the whole dash up, wiggle it or do whatever you need to - good to have a mate to give you a lift out.
You'll see how to remove it from there, you just twist the little screw holders 45 degrees, be careful they are delicate. I had one of those bulbs go, never got round to changing it, left it a couple of months and it started working again, like a good'un. Laziness DOES pay off.
