    Witajcie.

    Jakiś czas temu w moim VW Polo 3 (6n2, 1.4, 75KM, 2000r) zaświecił się Check Engine. Przy pomocy najprostszego interface'u (i bez zastanowienia) usunąłem błąd i był spokój jakieś parę dni. Po ponownym pojawieniu się postanowiłem zainteresować się bardziej. Oto ten błąd:

    Code:
    VCDS-Lite Version: Release 1.2
    
    Tuesday, 04 June 2019, 18:39:00.
    Control Module Part Number: 036 906 034 D
      Component and/or Version:  MARELLI 4LV       3458
               Software Coding: 00021
                Work Shop Code: WSC 31414
                          VCID: 13593C4F726D
    1 Fault Found:
    17559 -  Long Term Fuel Trim Additive Air; Bank 1; Range 1: System too Lean
            P1151 - 35-10 -   - - Intermittent


    W sieci jest wiele, powtarzających się, informacji na ten temat. Jedną z nich mówi że przyczyną może być nieszczelność dolotu powietrza. Po szybkim zerknięciu pod maskę znalazłem takie uszkodzenie (nieszczelność):

    Czy to może być potencjalną przyczyną problemu?

    Uboga mieszanka , pompa ,sonda itd ,gazu widze nie masz.

    Nie, tylko benzyna.

    Pozwolę sobie napisać post pod postem żeby odświeżyć temat.

    Wiem że przyczyn może być cała lista jednak większość internetu wskazuje na sondę lambda. Czy ktoś mógłby mi jasno opisać jak wykonać diagnozę takiej sondy (a może nawet sond) przy pomocy VCDS połączonego z moim Polo?

    Sonda powinna oscylować a nie stać na jednej wartości.

    To zdążyłem wyczytać tylko nie wiem gdzie w VCDS wejść żeby te wartości zaobserwować. Który blok dla VW Polo?

    Pamiętasz kiedy ci ten check się wyświetlił? Podczas postoju, jazdy?


    Pierwszy raz nie pamiętam ale pozostałe 2 "checki" zaświeciły podczas jazdy.

    Spróbuję według tego:
    Cytat:
    Block 002 - Load Registration
    - Check the MAF airflow reading at idle. Make sure the car is running and warmed up and the A/C is off. Go to Block 002 and look in Field 4. The value at idle should be between 1 and 25 g/s. If it's lower than 1 g/s, then there is probably a leak in the intake tubing between the MAF and manifold.

    Block 030 - Oxygen Sensor Regulation
    - Go to Block 030. Field 1 is a three-digit binary code which gives the status of the pre-cat oxygen sensor. Field 2 is the same thing but for the post-cat oxygen sensor. The digits indicate whether or not the sensor heater is working and whether or not the oxygen sensor control is operational and active. The value should fluctuate between 111 (heater on) and 011 (heater off). The last two digits can also fluctuate between '1' and '0', but should be predominantly '1'.

    Block 032 - Oxygen Sensor Control Learned Values
    - Go to Block 032. Field 1 represents the fuel trim at idle (additive) and Field 2 represents the fuel trim at part load (multiplicative), i.e., while driving. The value should be between -10 and +10% (negative indicates the engine is running rich and positive indicates the engine is running lean). If the value is close to +25% (which is the upper limit), it usually means that the MAF is bad. If the value is somewhere betweeen +10 and +25%, it could mean that the pre-cat oxygen sensor is bad, there is a leak in the intake or that the MAF is on it's way out. The value I found for my car (VR6), which has a new 2.0 MAF and new oxygen sensors is +1.6%.

    Block 033 - Pre-Cat Oxygen Sensor Control
    - Go to Block 033. The value in Field 1 represents the pre-cat oxygen sensor control. The value should fluctuate at least 2% in the -10 to +10% range.

    Block 036 - Post-Cat Oxygen Sensor Control
    - Go to Block 036 (this test must be done in basic settings, not measuring blocks). Depress and hold brake pedal to run the automated test. The engine RPMs should raise to around 1400. Field 1 is post-cat sensor voltage. It must fluctuate slightly between 0 and 1V. Field 4 will say either 'TEST OFF/ON' before/while the test is running and either 'B1-S2 OK' (sensor is good) or 'B1-S2 NOT OK' (sensor is bad) after the test is finished. Release the brake pedal after the test finishes.

    Block 034 - Aging of Pre-Cat Oxygen Sensor
    - Go to Block 034 (this test must be done in basic settings, not measuring blocks). Depress and hold brake pedal to run the automated test. The engine RPMs should raise to around 1400. Field 1 is the engine speed. Field 2 is the catalytic converter temp. Field 3 is the value which tells you how aged the sensor is (not sure what it's called). Field 4 will say either 'TEST OFF/ON' before/while the test is running and either 'B1-S1 OK' or 'B1-S1 NOT OK' after the test is finished. The aging value must be above 0.80. The value for a new sensor is 1.99. The value will decrease as the sensor ages. Release the brake pedal after the test finishes.

    Block 046 - Catalytic Converter
    NOTE: The test in Block 034 must be done just before this test or it will NOT initiate!
    - Go to Block 046 (this test must be done in basic settings, not measuring blocks). Depress and hold brake pedal to start the automated cat. test (last approx. 100 secs - the cat needs to be warmed up above a certain threshold for an accurate reading - the threshold is usually 400°C). The engine RPMs (Field 1) should raise to around 1400. Field 2 is the cat. temp. This will also rise during the test. Field 3 is the cat. conversion efficiency. If the cat is good, the value should be below 0.50 at the end of the test. Field 4 will indicate if the cat is good (CAT B1 - OK) or bad (CAT B1 - NOT OK). Release the brake pedal after the test finishes.
