Where is the flasher relay located in an Audi A6L?

[VonCassandra]

The flasher relay in older Audi A6 models is positioned on the left side of the engine. It is an automatic control device where the output undergoes a step change when the input (electrical, magnetic, acoustic, optical, or thermal) reaches a certain threshold. Function of the flasher relay: The flasher relay enables the turn signals or hazard warning lights of a vehicle to emit alternating bright and dim light signals while driving, effectively alerting nearby vehicles and pedestrians to enhance safety. Working principle: After the flash is fully charged, the flash synchronization contacts on the camera close the flash circuit. During the flash emission, light from the flash illuminates the subject, reflects back, and enters the camera (for exposure) and the flash metering element. This metering element quickly converts the light energy into an electrical signal, which is then fed into the integration circuit.
