intreruperi motor e46 150hp

eu cand am schimbat injectoarele la 110 mii nu am codat nimic, a mers fara nici o problema, cred ca la 136 de cai e treaba cu codarea.

136cp nu e common-rail, cu exceptia injectorului cu fir, restul sunt injectoare clasice, cu deschidere la presiune.

Tu ai noroc daca iti merge bine fara codare. Corect ar fi sa le recodezi. Citeste si aici: link.

 

 

When installing new nozzles need to be considered as the first 6 digits / letters.

The offset value (6-digit alphanumeric code) is stamped on each nozzle.

Enter numbers / letters in accordance with the installation location (cylinder) of new injectors.

- Select "Digital Electronic Control Diesel"

- Select the "correction, the correction of the fuel injection nozzles"

- Select the "Test Plan".

- For each cylinder by replacing one nozzle to introduce the correction.

Correction of new jets is necessary in order to ensure they are fully operational.

Salut tuturor

 

Pana sa se apuce fratele Krebs de treaba cu piulitele erau foarte multi care se plangeau de problema intreruperii si fluctuatiei turometrului la relanti,unde sunt acum?

Curajul lui v-a facut sa incercati si voi si in final asta era problema tuturor sau v-ati lasat batuti?

Mai veniti si p-aici cu cateva pareri daca ati incercat schema sa nu fie Krebs singurul norocos de rezolvare.

Ma bucur ca ti-ai rezolvat problema,cred k ai scapat de o mare piatra cand ai dat tura cu masina si ai vazut cum se comporta.

Bravo !

Cred ca a fost norocos. Eu am schimbat saibele degeaba. Doar dupa ce am facut egr-off din soft am scapat de intreruperi.

adjust egr to +40

Pt ce.i cu 'smuncituri,intreruperi' cauzate de EGR, nu.i nevoie sa.l anulati, trb doar 'ajustate valorile'

 

"Whilst cruising at higher speeds, typically on the motorway during constant throttle, there is an intermittent jolt like a misfire. the jolt / misfire / hesitation occurs once only.Typical speeds under which the complaint is present are; 1800 / 2000 rpm @ 60 / 70 mph

During cruising, EGR regulation takes place;- typically when re-applying the accelerator pedal. The actual air consumed by the engine increases but the measured value (actual value from HFM) does not rise proportionally in order for favourable fuelling to take place, this is because the EGR is open and an element of unmetered air negatively effects the calculated. The engine hesitates briefly as a result. 

 

In the event of complaint, carry out the following;

- Adjust the EGR, adjust rate of fresh calculated during EGR to +40 

- To do this use the service function of the DDE, adjust it by adding the value 40

- End with programming the DDE using the option in the ABL

- Following successful manipulation, let the vehicle assume sleep mode and then check the status of the EGR by entering the test module once more to ensure the value has taken place before carrying out a thorough road test.

 

Carrying out the above procedure does not constitute a fault with the engine as the wear 

characteristics of the engine and ancillaries may necessitate the need to adapt the DDE running parameters accordingly. 

 

It should however, be noted that the air and fuel system should be fault free prior to 

adopting such a change.

 

Poate cineva sa confirme cele spuse mai sus? Postul este de pe topicul"EGR - rol si functionare".

Am pus +40. Urmeaza o perioada de teste.

@djtaotao - sa ne tii la curent. Imi pun si eu la punct DIS ul si o sa incerc. :)

Se pare ca modificarea este una din solutiile salvatoare, cel putin in cazul meu. In perioada ce a trecut au fost si temperaturi de primavara cand de obicei apareau intreruperile.

Totusi, voi pune la loc softul cu EGR-off, pentru linistea mea sufleteasca. Ma simt mai bine stiind ca motorul merge doar cu aer curat. Sunt convins ca ecologia nu ne va salva planeta...

 

So, spread the news!

Merci pentru feedback. Acum nu stiu cat ai mers ca sa-ti faci o idee de consum. Am citit faptul ca ar creste si consumul care si-asa este crescut datorita clapelor lipsa din galerie. Vorbesc de mersul in regim urban.

Nu am monitorizat consumul cu modificarea facuta. Banuiesc ca nu se intampla nimic cu el. Din punctul meu de vedere modificarea cu DIS este un pseudo-EGR-off, iar eu cu soft EGR-off am un consum diminuat cu 0.5-0.6l/100km. Oricum nu pentru consum am facut toate astea... Edited by djtaotao

Am un x3 3.0d 2007 am aceeasi problema.

Intr-un interval de temperatura 5-25 de grade la relanti tremura masina de zici ca moare. Ma chinuie problema de 3 ani dar a inceput din ce in ce mai rau.

Am depistat de curand ca are legatura cu EGR adica da drumu la prea multe gaze si motorul ramane fara oxigen. De aici si mersul balbait ca in 3 pistoane. Practic motorul se sugruma in lipsa oxigenului.. Daca scot furtunul de vacum de la EGR se potoleste instant.

Precizez ca in ture merge foarte bine.

De cateva zile merg fara furtun la EGR si motorul la relanti merge bine in ture trage mai bine.

Valva de comanda a EGR am schimbat-o acum un an si nu a fost nicio imbunatatire.

Ce ar putea fi ?

 

A si am uitat sa mentionez ca atunci cand EGR activ aburul de la esapament are un miros intepator de nu poti sa respiri pe langa masina. Cand scot furtunul de la EGR nu mai miroase deloc.
