This is a trick some folks do to figure out if it's the starter. When the car doesn't crank, take something like a bat or a metal bar and hit the starter and few times. If the car starts right away then it's your starter, otherwise you might consider the fuel pump relay/fuel pump.
Your abs and traction control lights should only come on when you start to slide while breaking(ABS), and when your wheels spin in place when excelerating(TC). If those 2 things don't happen, which with some people they never do, you should never see the lights come on. Only when those mechanisms are in use do the lights come on. And they will always flicker as that is what abs and tc are, intermitant surges to break up the constant. ABS does this for obvious reasons...anti lock break, so when you slide, the abs "taps" the breaks in short bursts so they don't lock up. TC "taps" the exclelrator when it slips. Those "taps" are what trigger the lights on your dash, which is why they flicker and don't stay on.
when you first start your car, all of the lights on the dashboard should light up -- if there is no ABS light there, you probably do not have ABS on your car. The slightly more risky way to test it would be to take the car out on an unused access road and go about 20 to 25 miles per hour, then slam the breaks as hard as you can. If the tires squeal on the road, then you do not have ABS. Please make sure you are going to be safe if you try to test your breaks -- make sure there are no other cars on the road ... make sure the road is wide enough that if your car skids to one side or the other that you will not hit anything ... make sure that your wheels are straight when you hit the breaks so you do not lose control. If you do not have ABS, you should perform a controlled skid ... if you do, your car will not skid, and for just a moment you should feel your breaks take control for you (slight pumping motion of the pedal under your foot).
Generally, if there is ABS in a car, there is a light on the dashboard to warn you when the system is not working properly, so if you don't have a warning light, you don't have ABS.
most likely it just disables the abs which some people hate so depending on who owns it could be good , BUT i would get it checked cause on those vehicles i believe that on the wheel bearing is and abs sensor and sometimes it's easy to get caught & rip or pull wires off BUT like i said worst case NO ABS & abs is when you hit brakes hard they pulsate till ya stop and with no abs you hit brakes hard and they lock up till ya stop .
its a low speed abs activation the problem is in the front sensors they need to be cleaned or replaced they [or one] probably has some corrosion on the sensor --[the 99 chevy tahoes had a limited recall over this issue and the fix was to remove and clean the abs sensor or if to corroded replace ] this problem doesnt set off an abs code or trouble light also sometimes the abs will activate by itself at under 4 mph without even touching brake
sounds like your vehicle speed sensor is going out. it's the modern equivilent of a speedometer cable. it tells the computer how fast your going which the computer uses to determine shift points, abs function, and speedometer readings. they usually act up a bit before they go out. it confuses the computer. normally located in the extension housing at the rear of the transmission where the spedometer cable would be on an older vehicle
The rule of thumb is to start as far away from the master cylinder as poss. so it means you start at the right rear, left rear, right front, then at last left front. There is a little a little weep bolt on each calliper it needs to be un lossened when break is fully applyed then tighten weep bolt back up pump the breaks while weep bolt is still tight then hold brake pedal down to floor lossen weep bolt till a full steam of fluid comes out tighten bolt back up, now move on to the next break calliper and repeat this same proccess till you finished. Hope this works better than r/r l/r r/f l/f lol!!!!
Check brake fluid level first and foremost- top off as necessary.
1. Start with checking if sensor was reconnected - sometimes they will not seat properly. - were the sensor wires damaged during/after install.
2. Now in all VAG products I have owned with ABS the manual states that you need to perform a raod teat with at least 1 ABS event i.e. go on a gravel road or grassy area or if its icy/snowy just hit the breaks. This should set the ABS for normal operation.
The fact that you have an ABS light on tells me that you have a connector/sensor problem.
