My service traction light is one and my abs light is on


The abs makes the traction control work so fix the ABS first. The most common thing thea haqppens are the wheel speed sensers fail. In the front wheels the speed senser is incorperated into the front wheel bearing. these bearings are well known to fail at about 100 thousand miles and can fail aqs early as 80 thousand miles and most all of them fail before 140. You might notice a roaring sound ( like noisiy treaded tires) You can jack up one front wheel at a time and get in the car as your driving it and put the car in gear and run the car ( not moving but thwe trie is turing and listen for noise. I fht e wheel makes a roaring sound that gets worse as you go faster that wheel bearing is bad. Don't go over about 50 as with one tire on the groung the other that is turning, is going twice that fast or 100 MPH at 50 on the speedometer. Do the same test on the other wheel and if it's quiter or quite just change the noisy one. Once changed you just drive the car and the new wheel speed senmser will be reconized and the ABS light will go out as will the trac off light. If your ready to change both wheel bearings do so as they both have the same miles on them just not nessarily the same potholes and other rough pavement that makes them wear out faster. If thebearings are quite then you need to inspect the wires coming outr of the back of the wheel bearing.. Thjese wires get into troble and get unplugged or break the wire. If you havwe asscess to a scasnner that will address ABS systems it'll point out the ABS problem. Things that happen other than the wheel speed sensers are fuses blown for other reasons. The accumulater motor failure or extreamly cold weather the accumulate motor locks up in cold and blows the fuse. Thwe motors seldom fail but they can and do. Some veicals are nerer serviced and the brake fluild accumulates moisture ( as it's supossed to) and peaple never get the brakeing system seviced and the old brake fluild can freeze in cold weather and start croduing things. The Traction control sysem uses the brakes to control wheel spin by puting on the brake on the spinning wheel. If the system notices a wheel spinning. (Using the wheel speed sensers) So until the ABS is fixed don't try to fix the traction control system as it truly is part of the ABS systyem.

What is the problem when the ABS WARNING LIGHT COMES ON


When the car is moving and if there is change of RPM in one of the wheels the ABS will indicate the problem of wheel slipping and so apply the brakes to correct them to equalize so that there is no SKID.
Now if there is any malfunction also like a faulty sensor on the wheels or while accelerating there can be a mismatch in RPM, the lights can come on.
Cleaning the wheels , cleaning sensors might help to clean any of the irregular detection problems.

Audi 80 ABS problem


Hi there mate. I had the same problem. Have you got all the sensors the right distance away from the wheel? I think its 25 thow (excuse my spelling) and its the thickness of a matchbox carton. So just make sure the distance is right and the light should switch off. A trick is using super glue to stick some carton on the sensor and the pressing it in to the max distance. the wheel will push the cardbaord off by itself and it should be sweet.
