Hi - does anyone have any advice on how to change the bumper light? I bought a replacement for about £50 and thought fitting it myself would be better than paying Audi £300. However, the back of my car is (I now realise) subtly different to all the ones shown on YouTube how-to videos. The panel that gives access to the famously well-hidden screw is different. On my car it is not directly under the light. Any advice on how to locate the screw? It seems impossible Many thanks in advance
