98 a4 1.8T Quattro Manual---ok so i know this has been beat to death and i tried searching but at 1:40 in the morning and a million threads regarding the abs sensor, im a little fried heres the deal... just changed all 8 front control arms, tie rod ends, sway bar links, high pressure power steering line, both front axles, and brake line on the front driver side. (bled the brakes on the front driver side only) After a quick test drive down the street, i noticed my abs engages every time i brake. after about a half mile or so and a couple times braking, my brake light begins to flash and my abs light come on with it but stays on. As soon as the lights come on, my brakes works fine with no abs engaging. Someone please tell me what i did? something with the axles? something with the brake line?[headbang][=(]

wow that is odd, did something odd happen to the wiring for the ABS sensors, plunged them in backward or something? Does the ABS not work at all anymore?

Haha I know its a shitty time to need help lol but no nothing seemed to happen to any wiring I mean I had it unclipped but as far as I know nothing happened! Nothing was even un plugged the abs does work. everytime I turn my car off and back on the lights stay on then after a min go away then when I drive again everytime I brake my abs kicks in again untill the lights come back on then the abs quits kicking in... I'm assuming when the light comes on its sending a signal to the abs to quit working

does it engage at any speed or only at low speeds? usually when it happens at low speeds, 20mph-, it's the tone ring. take out your ABS fuse and see what happens. i've seen a 01 1.8t not start after the fuse was pulled so don't be surprised by that. also with the fuse pulled, you won't have cruise control or EPS.

Have you gotten the alignment done yet? Mine was off enough that it turned on the ABS and ESP lights after I replaced control arms.

I did not get into any high speeds as I did not have an alignment yet and I know its off quite a bit! jwatson that also answers your question and that makes me feel a lot better thanks for the advice ill let you know what happens after I get it alligned this morning

If you take out the fuse, it just wont work, better having one that doesnt turn on at all then one thats on all the time.

Sounds good I'm getting an allignment as we speak. It I don't even think pulling the fuse is necessary because as soon as the light comes on my abs no longer kicks in

Did you get any debris in front of the ABS sensor? I'm wondering if you have interference that's causing the ABS sensor to freak out?

you need to reblead the brakes, and of the code is just for the one front side then its prob bent or something with the speed ring in the axle itself

Wow, that must have been a relief! Glad you got everything sorted out, nothing worse than finishing a days worth of work only to encounter problems.
