    Hello,

    car like the subject, smokes in this way only when you press the accelerator pedal at low speed.
    The car's power is fine up to 160km / h is very good.
    Best of all, there are no errors in the ECU; / no clue.

    Looking at the parameters of the theses I have not seen anything disturbing, the temperature sensors all show approx.
    The amount of air measured by the flow virtually matches exactly what the computer wants.
    EGR valve also as indicated.

    120,000 km driven from the Polish showroom also has a reliable mileage.

    Fluid in the expansion tank is normal, the oil level since flooding it 3 months ago also.

    Logs to do? Just what exactly?

    best regards

    What I will check is injection correction tomorrow with VCDS.

    Damn 120,000 and pouring injection some new quality vw? I saw some of them but they were "German pearls from the Polish commission" which had a flight of probably 300-400 thousand.


    Tomorrow I will write a cod but this is probably the weakest or 90 horsepower.
    In the check I will check but it is to be excessively so?
    It looked tight but will check again. Pipes from turbo to suction approx.
    So cheap Once I asked it PLN 140 art and to the old lagoon II.


    It is just such a whitish balloon, but if it collapses a lot, it looks like in older cars a whacked seal under the head.

    There are just no errors.

    Thank you very much !

    The engine code is CAYH.

    Checking one injection is PLN 50 with me. They are not repairable as something is just a replacement for a new one as a piezo.

    The pressure on the rail I looked looks very good. The car lights immediately without difficulty, nothing goes off.

    Today, at the test, I blinded the egr and drove over. The same white smoke in the back. In addition, with an open and jammed car it would be weak and here nothing up to 140km / h accelerates very well.

    Logs flows for me looks efficient, I can not upload because the file has rozerzenie.csv how to bypass it? ; /



    EGR car got a new one generally it did not help (because it could not but the owner insisted :D ). Probably only those unfortunate injections remain.

    I have a similar problem ... until EGR fell apart.
    At the moment I replaced the EGR with a new one ... and the lambda probe (only after replacing the EGR did the probe error). After driving, the car drives normally for a while, then the knocking of injection / injections under load begins (e.g. at approx. 1300 revolutions and in the range of approx. 1800-2300 revolutions). It often falls into a 'mode' during which the revs rise, they can wave, the car starts to smoke, the injection knocks under load ... and after a dozen or so kilometers it normalizes and activates the DPF firing process.

    What stage are you at? Have you solved the problem? At the moment I'm waiting in queue to check the injection and system ..
    Did you make software updates? Did you set the injection angles?

    In my case, the patient is VW Polo 1.6 TDI CAYA from 2010. Mileage 66 thousand km.

    When browsing the Internet, topics with this engine are piled .. most problems look similar, however, the lack of specific analysis and solution to the problem. I will be grateful for any tips.

    Screen with injection measurements with underheated engine:

    Screen of injection measurements with a warm-up engine (cooling fluid 94, oil 91) but ... after flooding with LM Spulung:

    Skoda FabiaII 1.6tdi - Smoke white and blue under heavy load
    After adding LM Spulung to the tank ... idle consumption dropped from 0.8 l / h to 0.4 l / h and the injections began to clatter a little more quietly ...

    Below is the screen from DPF measurement, I don't know how to search for the amount of ash accumulated in grams, soot is at 16 but%?:

    I have locked standard measurement blocks, only advanced ones are unlocked, I would like to ask for a hint where and how to make these logs.
    In terms of errors I have scanned all 'modules' - no errors.
    Question: If the injection is damaged and the effect is that it pours, what can this problem occur sporadically? in the sense that it pours but pours sometimes or from time to time? is it raining non stop when it rains? :)
    I am asking because at the moment the car is driving normally outside, audible knocking of 'injections' at lower revolutions (1000-1500 rpm, 1-2 gears) or higher revolutions (1900-2400 rpm). However, the problem is that the car sometimes falls into 'mode' where the idle speed is higher and jumps, kicks and taps the previously described 'injections' harder. When the car travels at least a dozen or so kilometers, the process of firing DPF on the countertop starts, after the successfully completed process, it drives again normally but you can hear (smaller) knocking in the mentioned ranges of rotation.

    PS Tell me why you need information about the amount of ash accumulated in the filter ???
    For a proper diagnosis of the filter efficiency, a pressure difference and a temperature before and after the filter are sufficient.


    Thanks for the info, can you still tell what level should these indications appear (pressure and temperature difference)? I understand that you need to measure all these values on a warm engine?

    By the way, I will ask if after replacing the EGR for a new adaptation (VCDSem)?
