Multimeter Test measuring the obstacles. Do all have the same resistance or not - if the resistance is too high, and if it does not work then there is no obstacle too does not work.

Audi alroad abs light turn on


If the brakes are operating properly then check for dirt on the abs wheel sensor or bad sensor itself. If they're not working right then could be a number of things including the abs module on master cylinder. Sometimes you can swap out the electrical portion otherwise you may need to change complete unit. $$$$$$

Abs light on a 06 expedition


Having the vehicle checked for DTC'S - diagnostic trouble code's would be a good first step . ABS light on codes are stored . Suggest you take your vehicle to a qualified repair shop that has the knowledge an testing equipment to diagnose the problem properly .
Anti-Lock Brake System (ABS)
The 4-wheel, 4-channel anti-lock brake system (ABS) consists of the following components:
  • ABS module
  • Front wheel speed sensor
  • Front wheel speed sensor ring (integral to the front wheel bearing)
  • Hydraulic control unit (HCU)
  • Rear wheel speed sensor
  • Rear wheel speed sensor ring (integral to the rear halfshaft)
  • Yellow ABS warning indicator
  • As you can see here , it can set numerous

On what wheel does the speed censor sit


Hi there !

The speed sensor is always located on the Transmission and what are asking for is the Abs sensor which you can find on every wheel of the car just behind the brake rotors. Good luck

Mk1 A4 ABS warning light


I have a 2000 Audi A4 and the break wear sensor warning light come on for me too. It does not flash and is orange in color. I have asked the Audi dealer twice about it and they told me it's because the previous owner put aftermarket break pads on it, thus messing up the sensors. I don't know about the ABS warning and other than that I wish you luck on it.

Hi there i have a 1994 audi cabriolet 2.6 the problem is when i start the car the abs light comes on and it does not go off can you help me THANK YOU.


You have either a faulty ABS sensor (aka wheelspeed sensor - one at each hub on the car) or your ABS controller is bad. You need to have the car scanned by VAGCom (the Audi diagnostic scan software) - it will tell you which part is failing.

As I slow to a stop the ABS kicks on in my 2000 Audi s4


sounds like you got either a misreading(bad wheel speed sensor/abs sensor)
or a dirty sensor
or a broken reluctor ring on the axle
prematurely setting the abs to come on for no reason when your almost at a stop,,,,
i would take it to the shop,but its gonna be one of them things

Changed brake pads and fluid. Brake light/ABS light still lit.


Go back around and check to make sure you didnt accidentally pinch or cut a brake pad sensor. Also the ABS modules on VAG cars are pretty crappy.

Abs light and brack light flash wen u drive it


ABS sensor fault. This can be tested with a multimeter. There is a pick up sensor at each wheel on the car, usually reading off a castlated ring. Find the plugs for the sensor and set your multimeter to AC (the wiggly symbol) Use your test probes into the wires on the sensor side, and spin the wheel as fast as you can. The multimeter should read 0.2-2.0 volts ac. If nothing, then thats a faulty sensor.
Although i have given you a guide to doing this, it is better taken to a reputable garage with correct tools to have this test carried out.
