tocmai am revenit de la dealer...am facut o proba in miscare, dar nu-si pot da seama, parca ceva pe la servo-frana,poate ceva legat de abs, un arc... nu stiu si nici nu mai au timp sa verifice astazi, trebuie alta programare de dimineata ...pusca si cureaua lata.

daca face doar cand ai volanul rasucit e posibil sa fie un cap de bara...verifica in care pozitie a volanului face, daca il ai rasucit spre dreapta e capatul de bara din stanga si invers...nu-mi dau seama daca e acelasi sunet ca la mine, dar din ce povestesti e aceeasi situatie pe care am avut-o la fosta masina

nu...face si cu volanul drept. e ceva legat de pedala frana,servo-frana/ABS. face numai cand patinez pe zapada.
daca nu o sa mai fie zapada, nu am nici cum sa le mai arat la "maestrii" astia.

a 2-a vizita la dealer,probe in mers, tras de ea pe toate partile. Primul "meserias" zice ca poate sa fie ori de la servo frana ori de la supape ABS... Propune el pe banii mei sa inlocuim cutia de servo (1100RON) cu sanse 50/50 sa se rezolve..altfel mai vedem. Vine al 2lea meserias, trage si el de ea si zice sa si a lui face, chiar mai tare =)) =)) =))

unde esti mah TIBI, ca vad ca mecanica asta e mai ceva decat medicina, in puii mei....

Concluzie:
am luat un bax de bere si sarbatoresc ca nu am nimic de platit....

Greu de gasit "diagnosticul" la masina ta

Inca odata incompetenta din Romania iese la iveala,halal mecanici avem pe aici .
Daca mai dai de mecanici dastia,o sa bei multe baxuri de bere ,ca niciunu n-o sa fie in stare sa gaseasca problema ))

mda...frate am urmat drumul cel mai corect zic eu, mers frumos la "specialistii sefi", nu la vre-un service dorel srl. eram dispus sa platesc chiar daca era 1100 RON pt. rezolvarea problemei dar nu sunt dispus sa-si bata joc de mine nimeni,pe banii mei MUNCITI! Nu accept o firma mare sa ma injoseasca, "oi fi eu un purice mic, dar musc rau"

Sa stiti ca nu sunt genul snob sau panicat, ca domne numa la reprezentanta pot sa merg, dar in naivitatea mea am sperat si crezut ca pt. anumite probleme ce tin de siguranta mea si a celor din trafic, ar fi bine sa nu umblu cu jumatati de masura.

O sa evit pe cat posibil marile reprezentante pe viitor, niste carpaci obositi care stiu sa faca revizii si sa schimbe, NU SA REPARE!
NU o sa evit totusi baxurile de bere!

Daca aveti vre-un sfat despre ce ar putea fi..mai detaliez putin.


Deci, zgomotul apare la demararea pe gheta cand rotile se invart in gol si puterea motorului este taiata de ESP, daca ESP e OFF se aude la fel, dar puterea nu mai este intrerupta, daca derapez controlat cu frana de mana se aude iar (indiferent de starea ESP), se aude atat cu volanul rotit cat si cu el drept, predominant in treptele 1,2 si mai putin 3. Dupa ce se aude/activeaza zgomotul, pt. 30sec pedala de frana face un clac clac la apasarea ei, fara a fi mai moale/tare sau altceva. Dupa 30sec, se aude un alt clac si pedala revine la sunetul normal. Mie mi se pare ca ceva nu cupleaza cum trebuie (ABS/TCS) sau intra fara sa fie cazul.
O sa mai fac un filmulet cu zgomotul cand o sa pot. Zgomot similar se mai aude atunci cand franez pe zapada/gheta/etc si intra ABS-ul. Cred ca scriu degeaba,dar poate poate a mai avut cineva pe undeva problema asta.......

People, niste amici mai priceputi imi spun ca nu are treaba cu frana, ci ca este ceva intre EDL (nu stiu daca am asa ceva?) si ASR, chestii care ar fi mereu ON indiferent daca ESP este OFF sau nu. Stiti cum aflu daca am asa ceva ?

What is ELD?

ABS = Anti-lock Braking System
This uses sensors in each wheel hub carrier and a magnetic reluctor ring on the hub to sense the speed of the wheels. If during braking one or more wheels are going slower than the others, indicating that those wheel(s) have slowed their rotational speed (loss of traction/skidding) and could lock, then the brake(s) on those wheel(s) are released until those wheel speeds match the others.
Works on all wheels during braking only, to prevent wheel(s) locking and skidding. This is "ON" all the time and cannot be deactivated or switched off, unless the main fuse is pulled. The warning lamp on the dash will flicker on and off when the system has been activated, and you will feel a "pulsing" (quite sudden and heavy) through the brake pedal, as if it is trying to push back into your foot. If the warning lamp is permenatly illuminated, this indicateds a problem/fault with the ABS system, and that the ABS system is now deactivated to protect itself. In this case braking is "Old School" without ABS!

MSR = Mechanical (or Motor) Slip Regulation
This uses the engine's ECU to reduce the torque supplied to the drive wheels to reduce wheel spin, eg it reduces the power output (via the ignition timing/sparks/fuel, etc) of the engine to prevent further wheel spin, mainly when changing down gears on a smooth or slippery surfce. It has also been reported that whilst under full power (from standstill) coming out of a junction it has suddenly cut power to reduce wheel slippage, thus leaving you halfway across the junction now under reduced power! This function can not be deactivated or switched off, nor does it flicker any lights on the dash when it has been activated!

EDL = Electronic Differential Lock
This requires the car to have ABS to operate.
This will use the ABS sensors on the main drive axle (front) to sense if one of the drive wheels is rotating faster than the other. It will then brake that drive wheel until both the drive wheels are at the same speed. This works then the accelerator is being used and the brakes are not. Effectively this works as an LSD and is also known as "Fiddle Brakes" and has been used in F1, with manual versions used in tractors, hill climb racing, and 4x4 trail racing. This is always "ON" and cannot be deactivated unless the main fuse for the ABS unit is pulled. When this is working "Active" there is no light that flashes/flickers etc to tell you it is working!

ASR = Anti Slip Regulation
This requires the car to have EDL, MSR, & ABS to operate. This feature gives you a nice button on the dash with ASR (TCS on other VAG cars) on it and maybe a "skid" symbol.
This will use the ABS sensors to sense if the driven wheels (front on FWD) are rotating faster than the non-driven rear wheels . It will then brake the drive wheels (this system only brakes the drive wheels) until both the drive wheels are at the same speed as the rear non driven wheels. It can also use the MSR function to help reduce the power to the drive wheels if needed. This works then the accelerator is being used and the brakes are not. There will be a switch on the dash to deactivate this. The system is "ON" all the time. Pressing the switch deactivates the function and illuminates the respective warning lamp on the dash. If the ignition is then switched "OFF" and then back "ON", the ASR resets to default "ON" again! When this is working "Active" the warning lamp on the dash flashes on and off, indicating that it is currently sorting out the lack of traction!!

ESP = Electronic Stability Program (In this case NOT Extra Sensory Perception.. :giggle: )
This requires the car to have ASR (EDL, MSR & ABS) to operate. This feature gives you a nice button on the dash with ESP on it and maybe a "skid" symbol. This superceds/replaces the ASR (or TSC) button (you do not get both buttons)!
This system uses a gyro sensor (lateral acceleration and yaw) fitted either under one of the front seats or behind the lower central dash (usually on the exhaust tunnel) to sense cornering, g-force, etc, etc,. It will also use information from the ABS system, power steering wheel sensor, engine ECU, etc to work out what the car is doing and the current inputs by the driver. It then compares these actual readings against predetermined values and then according to the situation it will either brake individual wheel(s)(this system works on all 4 wheels), and/or reduce engine output. All to reduce the amount of under or over steer and keep the car on the course steered by the driver! The system is "ON" all the time. Pressing the switch deactivates the function and illuminates the respective warning lamp on the dash. If the ignition is then switched "OFF" and then back "ON", the ESP resets to default "ON" again! When this is working "Active" the warning lamp on the dash flashes on and off, indicating that it is currently sorting out the lack of traction and stability!!

a 2-a vizita la dealer...
unde esti mah TIBI, ca vad ca mecanica asta e mai ceva decat medicina, in puii mei....

Te rog frumos,medicina e ca o arta ...nu pune egal intre cele doua ca ne suparam
Am mai spus ca termenul de mecanic e cam impropriu pt angajatii unui dealer.Corect ar fi ''schimbasi de piese''.Cere-i unuia de acolo sa gandeasca,sa aiba o logica cand iti expune problema... ... multi sunt ghicitori(rudele mumei Omida),''cred eu ca ar fi asta''!
La dealer pana in prezent am dat numai peste incompetenti.Acum poate mai sunt si mici exceptii,insa sunt pe cale de disparitie.

Gata,l-am prins pe fraier (adica se aude bini di tat) am pus un tel si am filmat langa pedale. Primele zgomote se aud cu ESP ON in momentul in care trag frana de mana si pierde tractiune, apoi pe final tot cu ESP ON cand plec de pe loc si derapez. (noroc ca a nins)
Cu ESP OFF, daca derapez cu frana de mana nu mai face nimic si rar la plecarile de pe loc, derapat in momentul accelerarii.

Cu ocazia asta, ofer recompensa (pe bune!) oricui ma ajuta la prinderea nesimtitului care nu merge calumea!

Hai sa traiti (bine!)
Care stie daca se poate cumpara separat emblema de pe volan cu S-ul de la Seat? e cam roasa de timp si as vrea una noua si lucioasa

Craciun FERICIT!

si la mine se aude cv in genul asta dar undeva la rotile din spate pe la discuri tot la plecare....

ola, pana la urma am inteles din mai multe locuri (forumuri pe afara, mecanici) ca este un zgomot normal la masinile cu ESP + EDL (nu tcs,ca astea nu au si nu fac).
se pare ca abs-ul franeaza independent rotile din fata cand acestea pierd tractiune (la plecarea de pe loc, o rota fuge mai tare) iar cand pierzi spatele (tragi frana de mana) incearca iar sa franeze folosind abs-ul ...care face ca toate alea.

acum ca tu auzi la rotile din spate...nush ce sa zic, ca pompa aia de abs care face zgomotul e in fata, pe dreapta si e doar una...poate tu ai alta chestie?
