when pulling up last night to get some cigs,the audio chime came on as i was leaving the car altho i had turned off my lights (side and main)? when i returned the passenger side front/rear side lights had remained on,and when entering the car the audible chime was still on. once i had put the keys back into the ignition to turn the light switch on it was ok, altho i did try to copy what had happened the same thing happened again when i had turned off the lights and removed the key that the passenger side again remained on front/rear?? got a bit worried as to when i got home that this would happen again and find myself with a flat battery this morning.but it was ok when i parked up for the evening and all lights went out. phew!!! btw its a V plate s3 and not seen anything like this before?? what may be the cause of this my friends, please help cos no doubt its gonna happen again??
