After many times leeching from the forums i will try and help others out for a change!!.
My Lag 2000 V reg sport had very dimm display and was confused by other posts (ie removing dash?).
So here is a step by step of what i did to get it sorted.
First go to halfords and buy 2x these.
Then power everything off, haynes manual said disconnect battery but i couldnt be arsed for 2 bulbs.
Then lever up the front right of the panel as shown here:-
Then the front left:-
Then your left with the below pic, undo the two screws as shown (haynes said there were 3 but not in mine!!) I needed to put a nail and kinda pull them back whilst unscrewing as they arent in any kind of decent thread.
Then just lift out, turn it around so you can see the back, now the two bulbs are highlighted below. From memory im sure its 1/4 turn anti clockwise to get out and the opposite to get back in.
The little bulbs in the white holders just pull out , and basically reverse that to get all back working again and e-voila!
My display is back YAAAY!.
Hope this helps others.
