The clips are the most awkward ******* 'orrible
... that I have EVER come across..
Lower the wheel a bit... though I didn't on mine and that's almost right to the top.
Pull off the trip re-set knob. It's a inteference fit.
Slide something thin between the cover and the dash. A regular kitchen knife is fine. Put something on the dash to avoid leaving an imprint (piece of card, or tape is ideal).
The cover is now only held on by a couple of flat lugs with an "arrowhead" on the lower surface... that ride up the metal dash' clips before the "arrowhead" part drops into a slot in the clip. The tension of the dashboard pressing back on the cover holds it in place. So...
Press the cover in, against the "give" of the dashboard. Only 1 or 2mm will do it.
With your other hand, feel for the clip with the knife. Get the knife on top of the clip and press that down slightly then jiggle the cover up and forwards so the "arrowhead" bit disengages from the slot.
Do the other one.
First time I did mine I more or less leant on the dash with the knife and pulled the cover off using brute force and ignorance... luckily I didn't damage anything.. but when you see how it fits, it's essentially a press in, lift and pull out job.
Check you have the correct bulbs. The ones they sell in the Big H. etc. didn't quite fit in mine and I had to open the up bulb holes up slightly with a small file to get the black plastic body of the bulbs to fit into the hole.
they're a peculiar variety of bulb (£6 each from AR?
) but the re-work of the bulb hole works..
My last tip is "change all the bulbs" because Sod's Law that one of the others will go next week and you will be faced with doing this all over again..
