SOURCE: Hazard light and interior lights problem on 2001 A3

the indicator lights flashing constantly might be a warning from the car that all the doors have not been closed properly

after writing this ^^ i think that the system that tells the car if the door is open or closed it damaged or broken
and needs replacing

try leaving all the doors open and lock the car do the indicator lights flash contantly?

you need to get a dianostics done but due to the reson that it is intermmitant the problem will not exist when you get to the garage

check all the sensors that tell the car if the door is open firstly
