Hi i have a 1998 Audi A4 . I have the Check Engine , Airbag , (ABS) and Brake Lights on I would like for them to be truned off. There is No Audi Dealer around my town that im in.

Hi, we can supply you Audi A4 speed sensor ,also brake pad,brake booster ,calipers.
also can tell you more informations about how to install these parts.

as the mot only says the "brakes work"to a certain efficiency,(the tester does NOT check the depth/thickness of the pads),chances are your pads/discs are in need of replacement.the pads have sensors in them for wear depth, so when checking the pads,front AND rear the abs sensors can be cleaned,and if done by a seat/skoda/vw/audi dealer they can put it on the diagnostic computer to give you a definative answer (this is cheaper than guessing) I replace the pads myself but get the car "diagnosed"when any red light shows.

based on the age of the vehicle most likley the ABS module failed. Only way to know for sure is to get it diagnosed. There is nothing you can do at home without the proper tools. And no way can anyone guess accurately without testing. Codes are needed to proceed.

If the Airbag light is on, it indicates that a electronic fault is stored in the memory for the airbag. You will need to have a diagnostic check done to pinpoint what the fault is, have it sorted out and only then can the fault be cleared so the light will go off. The ABS light also indicates a fault on the electronic side of the braking system. If the light comes on as you start the vehicle this indicates that there is an open circuit in the wiring or that the ABS control unit itself is faulty. If the light only comes on once the vehicle is in motion, this indicates that a wheel speed sender is incorrectly fitted or dirty and not sensing the ABS Rotor on one of the wheels. If a CV joint has been replaced, the joint may not have an ABS ring fitted on it.[front] At the rear the ABS pick up is fitted on the inside of the brake discs and must be fitted to the new disc when replacing discs.

The speedo not working causes these 3 lights to come on due to the speed of the car needed for the ABS ESP to work . Engine management light is on due to the first 2 lights . Happenned to me last night. Dont know what is up with your speedo . You have to reset the lights after speedo fixing as I am uncertain whether they will reset themselves.

Hi
I don't think the lights on the dash board is anything to do with your sticking brake caliper ,it sounds to me like your instrument cluster is faulty
Hope this helps Nick

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.

ensure the ecu connection is good the plug for those sometimes need a good amount of pressure to put on abs light i would check the sensors next to your brake caliper to ensure its not broken or disconnect it or if you dont feel like checking it buy new ones and replace them

disconnect your neg. cable for about 30 seconds
