i've just spent more than an hour trying to change the headlight bulbs on my 2010 a3 sportback without any success. although it is a small 1.6 petrol engine, there is literary no space in the engine bay for hands. i've hardly managed to turn that one cap to uncover the two bulbs but it seems impossible to pick the holder of the bulb and swap the bulbs. ive bought a pair of fancy cool blue osrams but i cant fit them in any ideas except going to the official audi service??
