    Hello, I have a Skoda Octavia 2 with a 2.0 tdi engine, BKD 2005 code. After a long stop, the car does not start the first time, but the second time, and it does not start. Regardless of whether I shoot it for a second or 10 seconds, the first time it will not light up, it will not even sound, and the second time it will burn by touch. The problem occurs sporadically. What do you think ? Ignition cube? After connecting the computer there are no errors.

    If the ignition turns on and the starter is spinning, it's definitely not a cube. You have to look for what is missing, but if you say it is occasionally going to be hard.

    The problem is getting worse every day so it starts. I've run out of ideas, I don't know what the reason could be

    Have you changed your battery over the years?
    Or else, has it ever been discharged to such a level that it could not start?

    And what does that have to do with the starter spinning?
    You need to check what is not getting voltage the first time, e.g. if the injectors are activated and if there is a spark.
    Check if it is enough to turn on the ignition twice or do you have to turn it off after the first?

    A colleague has already read on his own on the Internet, why the spark is not there and never has been.

    It is important because in case of frequent discharge and overload of the battery, it can damage the computer controlling the engine, incorrectly set the controller etc. = topic found in the vw group

    And there's no pump in the tank there? Maybe it doesn't get electricity the first time.

    The pump is checked. Tomorrow I will see if there is electricity for the first time

    I had such a symptom, the replacement of the camshaft sensor helped, the old one did not generate any errors, and yet the replacement helped, but in your case it is a good clue, I do not know.

    Today I noticed that if I turn on the ignition a few times, it will start. I recently bought the car and the first week burned immediately, only after a week the problems started and the battery is Ok because it spins like crazy and I have never discharged to zero.

    Now you need to locate where the power is missing.

    Colleagues, there were two errors in the engine controller, today I was on the computer. The first is: 17978 Electronic control module engine operation blocked - discontinuous. Second error: 16618 Boost Pressure Adjustment; the end of the control range has been reached.

    So what am I supposed to do with it now, buddy? What is this error related to?

    The controller is blocked when the immobilizer does not work properly, i.e. it does not recognize the key, or there is damage somewhere (immo loop, key, ECU), there are various options. I don't think you can get it yourself. The computer is the basis for this vulnerability.

    Nonsense, give this immobilizer a break. Somewhere the fuel is dropping either because of a leak or because the pump is worn out. After turning the key several times, the pump in the tank tops up enough fuel and that's it.

    Just when he was checking for errors, there was no immo, there was no error, only in the engine. Replace this pump, there is no leakage anywhere, everything is dry. And the pump can be heard every time you turn the key.

    Problem solved gentlemen. I replaced the pump in the tank but it did not solve the problem, the car continued to fire some time until I was looking at a forum and there was talk about relay 458 in the engine compartment and decided to look at it. I cleaned the contacts in it and the car stopped starting at all, I replaced it with a new one and the problem disappeared. It fires every time you "touch" it. I consider the topic closed. best regards

Topic summary

The discussion revolves around a 2005 Skoda Octavia 2 TDI (2.0, BKD) experiencing intermittent starting issues, where the vehicle only starts on the second attempt without any error codes present. Initial suggestions included checking the battery, fuel pump, and ignition system. As the problem worsened, the owner discovered two error codes related to the engine control module and boost pressure adjustment. A key point raised was the potential immobilizer issue affecting the engine controller. Ultimately, the problem was resolved by replacing relay 458 in the engine compartment, which had faulty contacts, leading to consistent starting performance thereafter.
