Hi all, had my A6 since Feb, great car but recently had to go in for minor paint work when a pensioner decided he couldn’t park properly. Anyway, before the car went in I could have sworn that the interior lights came on when the engine was switched off....now they don’t. So did I imagine this or are the interior lights supposed to come on when the engine is turned off. All other aspects of the interior lighting work properly Thanks Ian
