What mistakes in ABS?

marlod · Answer

in ABS error it is not specified what the error is, whether it is an ABS sensor or something else, at the moment I do not know how exactly this error is described

Added after 2 [minutes]:

messages like "anttoluu defaillant system" and "ABS freinage defaillant" pop up on the display

Added after 4 [minutes]:

extinguish the engine, I start the errors again, there is only the engine error (check), then I can drive and drive until I exceed approx. 110km / h

Apparently your mechanic has poor diagnostic equipment. It's best to connect something good [e.g. DELPHI] has a lot of functions, among others, it reads the actual speed of each wheel separately and compares, maybe one sensor above 100 starts to lie and hence these problems. And you will know where to look. And those who exchange at random is a lot, they do not pay, you pay and he is happy.

thanks, it's hard today for a mechanic who will find the cause and something will only be repaired by most mechanics, it's not mechanics but "exchangers" after people's forums write that it can be a lot of things, e.g. corrosion on an ABS sensor, thin pads, tire pressure, tires with different sizes, acceleration sensor and it is not known where to look, and giving the car to the next master of mechanics can once again end up with gigantic replacements and costs for them.

question: start checking and possible replacement of ABS sensors on the wheels? or from something else?

T5 · Answer

From checking the tire size on the front and rear axle. From entering the error code.

marlod · Answer

at the front 225/55 / r16 at the rear 225/60 / r16

With such laconic information, you can go to the fairy, it will definitely help. Added after 40 : Bingo. Do you already know where you have a problem?

marlod · Answer

with the error code it will be worse because to give it here I have to go to the computer diagnostics: /

T5 · Answer

Put it on 55 or 60 all 4 and the problem will disappear.

marlod · Answer

Bingo? I wish it was the size of the tires but unfortunately: I have been riding these tires for 4 months and riding them before was not a problem. Maybe I will start from the beginning, the first I got an engine error (error egr) unfortunately I drove about 2 weeks with this fault and during this drive about 2-3 days after the EGR failure BSM / BSI errors and ABS, manual, ESP, engine check, STOP on the screen. I mentioned EGR errors cleared and everything worked until the speed limit exceeded 110km / h

T5 · Answer

Will you even put it on a trial?

marlod · Answer

so tomorrow morning I will put on 4 newly purchased summer tires specifically to check it, if it is the fault of the tires then Monday I will be dripping well!

Added after 1 [minutes]:

Otherwise, when I do nothing, I go to the computer and get to the errors that are and I have problems in the forum. thanks

luzik e34 · Answer

This difference in tire dimensions is not as big yet. As I wrote, check the speed on the wheels, maybe some lace is rusty and the sensor is lost with the reading at higher speeds'

marlod · Answer

and there is still a possibility, I have a broken hand and my jaws sometimes don't bounce, maybe it holds somewhere and it can also cause a bad reading and these errors?

dzik69ku · Answer

And what was the reason?

jbrizwan · Answer

Hi, check any wrong tire size fitted on the vehicle, like one tire wrong size.
