Can some one please help - I have bought a new bulb for my car and was told by audi to fit it myself as it was straightforward and would save money. Fair point I thought. Off I went bought a screwdriver and started to take it all apart - only one problem though I am not mechanically great and when I try to take the casing out, it does not come out that far - seemingly not far enough to put the bulb in and all back together. I also cannot remove the old bulb from the wire - is this just a case of pulling as hard as you can. Can someone please offer advice, the casing seems to stick due to the wires being all tied up so only comes out about 5 cm's - enough to get your hand in but not then to see very much !!
