I got the Audi led kit for half price, still a rip off if you price the bulbs individually mind but I’m a sucker for genuine accessories so...... Anyway, fitted the bulbs into the main light and the reading lights. All work fine when you enter or leave the car etc. It’s when the engines off and you turn a reading light on. It works for a few seconds then goes very dim then flickers. It works perfectly when the engines running or when you unlock the doors or remove the key to exit the vehicle.
