What does it mean when the brake light is blinking?
A red light that flashes on and off could signal low/almost empty brake fluid, but also a serious issue with the brake’s hydraulic system. If the light comes on and stays on, you could end up with a potentially catastrophic (and costly) brake failure.
Why is the brake light on in my Audi a4?
Bad Level Sensor: Your master cylinder is equipped with a brake fluid level sensor. It’s sometimes mounted in the side of the sensor, and is sometimes part of the reservoir cap. If the sensor fails or is going bad, the Parking Brake light will turn on.
What does brake light mean on Audi?
The Brake System Alert light comes on, this means your vehicle is at a dangerously low level of brake fluid. More than likely, this means there is a leak. Service is required and towing is recommended to avoid the potential dangers of brake failure.
Does my Audi have brake sensors?
Almost every Audi for the past 20 years has been equipped with electronic brake pad wear sensors. Most of them mount the brake pad with a clip, but some are molded into the brake pad. These sensors change their electrical resistance as the loop of wire is worn down and eventually breaks as the brake pads wear down.
What is the violation if a driver is operating a vehicle with blinking brake light?
Under RA 4136, the blinking/strobe stop light bulbs can be argued as a violation because most of the ones we see on the road blink whenever the brake pedal is depressed; often there is is no steady red light like OE-style bulbs that can flash during emergency braking maneuvers.
Do Audi brake sensors need to be replaced?
Since a pad wear sensor is a part of your brake pad system, it doesn’t need to be replaced on its own. You can simply get a new sensor installed whenever you get a new pad. It’s also recommended to get your sensors inspected as a part of your regular brake service and allow a pad change when necessary.
How many brake sensors does a Audi have?

What does the brake warning light mean on a Audi A4?

What does the brake light mean on a Honda Accord?
It is different than the anti-lock brake system, which gets its own ABS warning light. The brake light indicates that there is a problem with the physical braking system itself.
What does the pressure differential switch do on a Audi A4?
The pressure differential switch measures the difference in pressure between the two circuits and will report that there is a difference by turning on your A4’s brake warning light. In most vehicles this switch is located in the master cylinder.
What happens if brake fluid is leaking from the pads?
If the brake fluid is leaking out over the brake pads and shoes, it means poor brake performance. Just remember, it had to leak out somewhere, and that adding fluid without fixing the problem is just a temporary solution. The leak can get worse over time and lead to brake failure.
