When I press the brake pedal there is a loud audible noise and if I use the left indicator ant the same time the noise becomes much louder. If I use the left indicator without touching the brake pedal then the radio light flashes with the indicator. The indicator light on the left rear also just stays on. I've creared the DTC several times to cancel the engine management light but as soon as I drive again and use the brake pedal, the engine management light comes on again.
