Witam
Od pół roku wyskakuje mi wciąż ten sam błąd Mianowicie:
16785 P0104 Recyrkulacja gazu wydechowego (EGR) niewystarczający przepływ.
Spotkał się ktoś wcześniej z tym problemem?, zawór był wymieniany nic nie pomogło. Drugie pytanie czy w waszych polówkach przy włączaniu zapłonu, pali się lampka check i gaśnie dopiero po odpaleniu czy gaśnie przed i zostaje tylko lampka EPC.
pozdrawiam i proszę o pomoc

SKoro wymieniłeś zawór to musisz zrobić jego adaptacje. Nie dam ręki uciąć, że we wszystkich silnikach benzynowych trzeba ale robiłem to już w skodzie fabii 1,4 16V MPI, pomogło. Musisz zobaczyć czy nie jest już gdzieś za dużo nagaru w okolicach zaworu (musi być odkręcony). Samochód ocenia przepływ przez zawór recyrkulacji spalin na podstawie przepływomierza lub czujnika podciśnienia w przypadku gdy nie ma przepływomierza. Wyczyść przepustnice, zrób ponowną adaptację.

Na początek dobrze jest wykasować nastawy podstawowe.

01 - Silnik
potem adaptacje
potem w kanał 00 wartość 0
testuj zapisz i gotowe.

Potem adaptujesz przepustnice następnie zawór EGR zgodnie z niższymi instrukcjami.

Procedura adaptacji zaworu EGR Vagiem

[Select]
[01 - Engine]
[Meas. Blocks - 08]
Select Group 074.
[Go!]
MVB 074.1: Min Position in Volts
MVB 074.2: Max Position in Volts
MVB 074.3: Potentiometer voltage
MVB 074.4: Adaption status: (Run/OK/etc)
[Switch to Basic Settings]
MVB 074.4: Adaption status: (Run) then it should change to (ADP OK)
[Switch to Measuring Blocks]
[Close Controller, Go Back - 06]

Special Notes:

* For ECU's using ME 7.5, the coolant temp needs to be between 10 and 50 °C.
* In case the adaptation fails switch OFF the Ignition for 30 Seconds, then switch it ON and try again.

Tu masz jak zaadoptować przepustnicę


Cable-Throttle Engines

(These are engines with a physical cable between the accelerator and the throttle, but WITHOUT an ISV.)

Turn the key on but do not start the car.

* [Select]
* [01 - Engine]
* [Measuring Blocks - 08]

Enter Group 098 (Note: Some SIMOS or Marelli ECU's use Group 001 such as ADY & AEE engines)

* [Go!]
* [Switch to basic settings]

Once you do this you will see the top right display say ADP RUN. The TB adaptation is being done as soon as you switch to basic settings. You will see the values change and hear the TB cycle for the first few seconds then it will stop. Leave it in Basic Settings for about 30 seconds.

* Click the [Switch to Meas. Blocks] button and you're all set.

Be sure not to touch the accelerator and make sure the engine is NOT running when you do this!


Drive-by-Wire (DBW) Engines using KW-1281

(These are engines WITHOUT a physical cable between the accelerator and the throttle. Check to see if the engine speaks KW-1281 by looking in the top left of the Open Controller Screen Some examples of KW-1281 engine controllers are 2000+ Golf/GTI/Jetta/New Beetle/Audi TT 1.8T)

Turn the key on but do not start the car.

* [Select]
* [01 - Engine]
* [Measuring Blocks - 08]

Enter Group 060

* [Go!]
* [Switch to basic settings]

Once you do this you will see the top right display say ADP RUN. The TB adaptation is being done as soon as you switch to basic settings. You will see the values change and hear the TB cycle for the first few seconds then it will stop. Leave it in Basic Settings for about 30 seconds.

* [Switch to Meas. Blocks] button and you're all set.

Be sure not to touch the accelerator and make sure the engine is NOT running when you do this!


Drive-by-Wire (DBW) Engines using KWP-2000 or CAN

(These are engines WITHOUT a physical cable between the accelerator and the throttle. Check to see if the engine speaks KWP-2000 or CAN by looking in the top left of the Open Controller Screen. An example of a KWP-2000 engine controller is the 2002+ B6 Audi A4 1.8T. Some examples of CAN engine controllers are the Mk5 Golf 2.0T FSI)

Turn the key on but do not start the car.

* [Select]
* [01 - Engine]
* [Basic Settings - 04]
* Group 060
* [Go!]

It should say "Basic Settings: OFF" on the top of your screen.

* Click [ON/OFF/Next] to turn on Basic Settings.

It should now say "Basic Settings: ON" on the top of your screen. Once you do this you will see the top right display say ADP RUN. The TB adaptation is being done as soon as you switched basic settings on. You will see the values change and hear the TB cycle for the first few seconds then it will stop. Leave it in Basic Settings for about 30 seconds.

* Click [ON/OFF/Next] to turn off Basic Settings.

It should now say "Basic Settings: OFF" on the top of your screen

* Click the [Done, Go Back] button and you're all set.

Be sure not to touch the accelerator and make sure the engine is NOT running when you do this!

Special Notes

* In some engines, before doing a TBA, it may be necessary to cycle the ignition off and back on after clearing faults.
