F10 ZF8 nu "apasa ambreiaj"


Drey

Recommended Posts

Salut prieteni,

 

Conduc un 520D F10 din 2013 cu ZF8.

 

Astazi de dimineata, am pornit ca de obicei masina, am bagat in drive si am pornit spre servici.

Nu am apucat sa merg 100 m pentru ca a trebuit sa opresc sa dau prioritate intr-o intersectie si cand am apasat frana, a inceput sa vibreze toata masina si intr-un final a murit motorul. Senzatia a fost aceea ca atunci cand nu calci ambreiajul la stop.

 

Masina o detin din luna mai a acestui an si este prima oara cand face asa. Restul drumului pana la munca (16 km) s-a comportat ok si la schimb viteze si la stop.

 

Sunt incepator in ceea ce priveste cutia automata (dpdv mecanic) si de aceea as fi tare recunoscator oricui ar putea sa ma ajute cu un sfat.

 

Multumesc!

Nu cred ca este problema la cutie.

Verifica EGR.

 

Iti multumesc pentru raspuns.

 

Incerc sa inteleg totusi care este legatura dintre EGR si faptul ca nu a "apasat ambreiajul"? :unsure:

Adica senzatia ce mi-a lasat-o a fost efectiv ca nu a apasat ambreiajul, in sensul ca desi eu apasam frana ea vroia sa mearga inainte si vibra din toate inchieturile pana la un punct cand a murit motorul si mi-a aparut pe bord avertizarea ca masina nu este in P. Practic a scos-o pe liber (N) cand a murit motorul.

 

Imi poti explica putin te rog?

Ai patit ceva similar?

Poate fi același simptom cu “a dat ĂŽn nas”. S-a bușit amestecul de aer/gaze, motorinĂŁ și de aici suspiciunea. FĂŁ o diagnozĂŁ ca sĂŁ fii sigur cĂŁ nu te lasĂŁ când e lumea mai dragĂŁ.

 

Sa inteleg ca tot EGR suspectezi si tu?

Si daca ar fi de la cutie, ce ar putea sa fie?

 

Ce am citit pe net, ar putea fi torque converter (care nu stiu cum se traduce pe romana decat convertor de cuplu) sau ceva pe la valvele solenoide.

 

Apropos, in vara am schimbat galeria de admisie cu tot cu acele mici clapete din cauza ca era crapata si mi-a fost frica sa nu se rupa vreo bucata sa-mi intre in motor dar la EGR parca nu au umblat baietii.

Schimbul a fost facut la reprezentanta BMW din Pitesti.

Cred ca ii spune convertizor de cuplu. Colegii te-au sfatuit bine sa mergi sa faci o diagnoza. Te ajuta mai mult decat orice parere. Problema se pune atunci cand diagnoza nu gaseste nimic.

Mie pe bord nu mi-a aparut nici o eroare (in afara de avertizarea cum ca nu este bagata in P si ca poate sa plece masina la vale)... dar e posibil sa fi stocat ea ceva intern si sa apara pe tester...

Voi trece pe la o diagnoza sa vedem ce si cum

Nu se opreste motorul din cauza convertizorului.

 

Am citit pe net ca asta este una din cauze...

 

Your car is designed to run like a well-oiled machine, but sometimes that machine struggles in unexpected places. There’s not always a warning light to alert you of this, but sometimes your car will be driving fine at road speed, only to die when you slow down and stop. If your engine shuts off at low speed, contact a mechanic immediately for a thorough inspection.

 

Common reasons for this to happen:

Malfunctioning transmission: In a car with an automatic transmission, the torque converter takes the place of the manual clutch and is responsible for transmitting power. If the torque converter is broken, or if there is a low fluid level in the transmission, the converter will not do its job, and the car will be unable to maintain power at low speeds, which causes the engine to shut off. A defective TCS or torque converter solenoid can also cause this issue.

Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine. A malfunctioning fuel pump can result in low fuel pressure, which means that there is an inconsistent stream of fuel to the engine. At high speeds this doesn’t matter as much, but at low speeds a temporary pause in the fuel stream is enough to kill the engine. The fuel injectors are responsible for spraying a measured amount of fuel that is ignited by the spark plugs at the proper time. Injectors can become clogged or dirty over time resulting in erratic spray or no spray at all.

 

Bad oxygen sensor or mass flow sensor: The oxygen sensors and mass flow sensor determine how much oxygen is entering the fuel stream, and helps the vehicle adjust the air-to-fuel ratio. If there is too much or too little oxygen, your vehicle will not have optimal power. Just like with low fuel pressure, the car will continue to operate at driving speeds, but this suboptimal power won’t be able to fuel the vehicle as it slows down.

 

Loose or corroded wires in wiring harness: An inconsistently firing ignition will result in an easily stalled engine. If the wires don’t have consistent, constant, and reliable connection with the ignition circuit, the vehicle can lose voltage quickly, and it won’t have the power it needs to keep running as you slow down.

 

Faulty idle air control actuator: The idle air control actuator controls the engines RPMs when it is idling. This actuator receives information from the electronic control unit (ECU) so it knows at what RPM to keep the engine for a smooth and safe idle. When the actuator malfunctions, the engine gets no signal for idling speed and stops working.

 

Clogged or restricted EGR Valve: If your EGR valve is clogged, dirty, or defective it can cause your car to stall, idle erratically, or sputter, depending on whether it is stuck open or closed.

Ai facut diagnoza?

 

Deocamdata nu. Am fost foarte prins saptamana asta.

 

Masina s-a comportat normal. N-a mai avut niciun simptom de atunci. Am mai citit putin pe internet si cica mai fac din cand in cand asa :unsure:

 

O sa merg sa-i fac o diagnoza. Poate ajung maine.

Va tin oricum la curent.

Salut,

 

 

Detin un F10 525D aceasi simptoma o am si eu dimineata la rece cand cuplez cutia in D, mentionez ca am schimbat uleiul in cutie + distributie + curatat galerie admisie + clapete inlocuite si cutia schimba bine la cald.Incerc sa aflu care este problema din pacate nu am gasit un service sau mecanic competent sa ii dea de cap.

Dupa 10 minute de mers cu masina vibratile dispar ( Vibratile apar doar daca stau la semafor in Drive sau cand plec dupa loc ). :blink:
