Probleme cu motorul Z16SE astra G 2002

Subject: Coolant Temperature Sensor - Wiring harness connector poor contact
Models: Engines: Option:
Corsa-C Combo 2002...,Astra-G 2001...2002 Z16SE,Z16SE
Complaint: Engine jerking may occur while driving and while rough idling engine may stall. Engine - poor startability.
Cause: Vibrations at connector of coolant temperature sensor cause contact problems.
Production:

Subject: F17 Transmission - Insufficient 1-2 and 3-2 shifting behavior under cold conditions
Models: Engines: Option:
Corsa-C 2001...2003,Astra-G 1998...2003,Zafira 1999...2003,Vectra-B 1996...2002 All,All,All,All F17 Transmission
Complaint: It might be possible that - even if the transmission is correctly adjusted- a stiff and/or inexact shift mechanism occurs especially at cold conditions. As the transmission oil becomes warmer the shifting behavior improves. This is definitely not a transmission damage, the durability of the transmission is not affected.
Cause: Problem might be caused by: - Sliding gears are out of tolerance. - Feathering at the synchronizers. - Oil stiffness.
Production: Modified sliding gears have been implemented in production since June 2002 with transmission number A10721F17.

Subject: Coolant Temperature Sensor - Wiring harness connector poor contact
Models: Engines: Option:
Corsa-C Combo 2002...,Astra-G 2001...2002 Z16SE,Z16SE
Complaint: Engine jerking may occur while driving and while rough idling engine may stall. Engine - poor startability.
Cause: Vibrations at connector of coolant temperature sensor cause contact problems.

Subject: Engine - Cleaning Operation EGR / EGR-ports
Models: Engines: Option:
Astra-G 2001...2002,Corsa-C 2001...2002,Combo 2001...2002,Vectra-B 2000...2002,Zafira 2001...2002 Z14XE| Z16XE| Z16SE,Z14XE| Z18XE,Z16SE,Z16XE| Y16XE,Z16XE
Complaint: Engine poor idling.
Cause: EGR-Valve contaminated with foreign particles.
Production: As of 25.May 2002 modified parts have been used in production. Please refer also Technical Service Bulletin 1538.


Subject: Engine - Jerking, stalling and/or setting of TC's
Models: Engines: Option:
Corsa-C 2001...2002,Astra-G 2001...2002,Vectra-B 2001...2002 Z14XE| Z16XE| Z16SE,Z14XE| Z16XE| Z16SE,Z14XE| Z16XE| Z16SE
Complaint: Driveability complaints
Cause: Often these complaints are caused by a wrong variant / CAN configuration of the vehicle. This appears especially after cross changing or replacement of ECUs. Service ECU's are delivered with basic settings Transmission 'CVT' (Continuously Variable Transmission). This transmission type is not produced yet . It is necessary to set the correct transmission type (MT/AT)

Din TIS...
Technical Service Bulletin 1538 nu l-am gasit inca.

Am verificat cupla de la senzorul de temperatura si pare in regula (nu are joc iar contactele sunt in stare buna). Banuiesc ca daca era o problema cu aceasta as fi avut si ceva coduri de eroare in ECU + s-ar fi vazut si pe indicatorul de la bord.
Mi-a mai sugerat cineva sa verific culbutorii (el a avut o problema similara cu un Cielo si era de la distributie), dar as fi vrut sa epuizez toate celelalte variante inainte sa ma apuc sa demontez distributia.

Alte idei?

Problema s-a mai ameliorat de cand s-a racorit afara si nu mai bag benzina decat de la Rompetrol (efix). Cu toate astea, mai are momente cand merge mai prost motorul (nu trage si apare zgomotul de care ziceam).
Intre timp i-am schimbat termostatul pt ca am constatat un lucru ciudat: cand e frig afara (sub 10 grade) daca merg cu viteza constanta de peste 50 km/h temperatura motorului scade pana sub linia de 80 de grade.
Mai are cineva aceeasi problema?

Am uitat sa spun, nu este nicio diferenta dupa ce am schimbat termostatul. Ciudat este ca pe termostat scrie 92 grade. Am dat pe el 35 RON la opelshop. Mi-a luat o zi sa-l schimb (trebuie data jos cureaua de distributie+capacele de protectie).

Caldura in habitaclu este ok, de acord.
Eu am afirmat ca avem un motor friguros pentru ca m-am gandit ca se incalzeste relativ greu (am masurat, la 0grC afara, i-au trebuit 5 km fara semafoare, parcursi in ~8 min sa ajunga la 85grC) si se raceste repede dupa ce opresti motorul, parca prea repede, adica dupa 40minde la oprire, la 0grC afara, e si motorasul la fel de rece.
In mod cert, noi suntem influentati si de lipsa scutului motor, de lipsa antifonare capota, lucruri care fac foarte usoara racirea motorului.

Off topic: oviudium, in legatura cu EGR vezi topicul meu https://www.clubopel.com/viewtopic.php?p=103320
Va urma in curand si un topic despre fabricare scut motor pentru z16se-urile noastre.

da, poate ca se raceste, pe de alata parte, vara, kestia asta prezinta un avantaj... major as zice:)

Tot cu Z16SE si eu! Probleme sunt la caldura, in sensul ca iarna sub 3 grade imi trebuie un carton fatza, bine asezat si am rezovat problema caldurii! Eu m-am gandit sa-i fac o masca din aluminiu pe interiorul grilei sa fie ceva mai bine facut. Cu valva EGR, deja m-am consolat... De fapt nu stiu daca este cauza principala! Motorul merge foarte bine cu exceptii la consumul de ulei, dar nu am motive sa ma plang. Bafta!

Vezi ca ai trimiteri una la alta....citeste tot si succes !
Mai ai si senzorii de camshaft/crankshaft dar mai intii curata throttle.
Mai era unul care a rescris soft degeaba....
Depinde cum ai curatat si daca ECU a invatat noile valori, vezi ca am scris, pui contact si lasi asa pina vei auzi motorasul din throttle cum face cursele complete dupa care tace.
