Hi that looks crazy I’ve been looking around and don’t see any other makes with the problem how can the lights be watertight there is small holes all the way along on the light bar the washing excuse is ridiculous on a prestige car I personally take my cars to the same car wash I’ve used for years 3 Q7’s and 2 S5’s no problems ever . The front lights on the Q8 mist from the inside from new its actually in the manual saying this is normal but I think they have problems with the lights which is a shame on a otherwise fine car
