    Hello

    In the Mercedes ATEGO TYP 1323, year of production 1998 170 kW, CODE INS 03620 is displayed (probably a failure of some air sensor), the car has been running for a few years in the company, it was serviced in various workshops and they did not see this problem there, explaining that in these types of a fault pops up for a moment and it should be like that.
    There is no problem with the car, in general, except that only when I drove it personally, I saw that the air beats up to 12 atmospheres and there is already a red line on the meter at 10 (they have been driving it like this since I bought it, i.e. around 2005. Is there something about this to do (because in my opinion this should not be the case) and how to possibly fix it, how much does such a sensor cost? VIN WDB9702671K349217.
    In addition, the ABS has now started to glow, but this is probably another failure, most likely the sensor.
    In addition, the Mercedes is also converted from a tractor to a tipper ACTROSA TYP 1835 KS. In it, in turn, the cabin sensor lights up (maybe someone knows how to repair it) was also at the mechanic's, they did something, it was calm, now it shines again, most often when braking. At the end, maybe someone will advise how much Mercedes should burn? It had standards of 36 for the city / construction, 32 for the route, but after my checking it turned out that he burned empty about 30 on the route, but I don't drive trucks every day, with 3-4 liters he burned more for me.
    I immediately reduced the norms to 32 construction / city 28 route, anyway, it seems to me that the dump truck, which has 260 kW under the hood, does not feel much like 9 tons on it.
    In fact, I think about GPS, because it is probably the best solution.
    Thanks in advance for your help.

    3620 is a condensate sensor on the tank. As for the pressure, you just need to adjust it or repair the dryer. If you want, I invite you to Rybnik for a workshop.

    Thanks for the help.
    The dehumidifier was replaced last week, and how is the pressure regulated?
    Supposedly on washers, because the valves are electronic and have no regulation. Do you have to delete the error after this adjustment to make everything ok?

    But you didn't believe it, did you? Incompetence and that's it.
    As for the 3620, it indicates a sensor failure - so simply replacing the dryer cartridge will not solve the problem. Check the harness leading to the sensor (three wires), as it can often overheat in the vicinity of air tanks.
    As for the four-way valve - it is just a mechanical valve and there is no electronics there. Only the pressure reading is electronically. Here is a little curiosity: exceeding the value of 12 atm causes the disappearance of the indication on the dashboard. So let's not look for no contact in this case - just adjust the pressure accordingly.

    The dehumidifier consists of a base (includes a pressure regulation system and an air cleaning system) and a replaceable cartridge. In the base there is an allen key regulator and it allows you to change the pressure at which the so-called "rebound" occurs. As for the washers, I have not heard about the electronics, for example in the Scania R it is, but in the Atego 1998 it does not seem possible to me.

    Gerri, I am asking for help in Atego 1218 from 2004 4-cylinder engine, I do not know vin.
    The fuel gauge does not work and the error INS E 01 0508 shows. I figured something with the plus is wrong, but the current is at the tank, so what could be wrong? Thanks in advance.

    After all, there is this plus with the tank - is it not there?
    INS 0508 - the fuel level sensor has an open or a short circuit with the positive pole.
    These sensors break down (sometimes). For a test (if you do not have any resistor at hand), you can connect a 24V relay at the tank instead of the sensor. Its coil will serve as a trial resistor. The pointer should deflect noticeably when attached. You just may not know that after connecting, no matter what (be it a resistor or a fuel sensor), you should turn the ignition off and on again, because the pointer will not swing out otherwise.

    Condensate sensor on the tank, is it the sensor that is under one of the air tanks?
    And one more request for clarification, my 2000 Atego 815 does not have a drain valve on the bottom of the tank, there is what I think is a "condensate sensor on the tank". If so, how to drain the water?

    An efficient dehumidifier will not let water into the system - that's why the valve has been abandoned.

    Please confirm that the condensate sensor is located at the bottom of the tank.

    Gerri's colleague is wrong, in Mercedes Atego, where a condensate sensor is used, there is a water drain in the sensor at the bottom of the tank. This sensor has a water drain valve, but due to the possibility of its contamination it is hidden under a rubber plug pressed onto the body of the sensor. After removing it, by pressing on the body from the bottom, water is released from the sensor, getting rid of the error in question.

    It's always fun to learn something new. I saw this rubber cover, but I did not inquire what it was for. I actually checked, and it is as you wrote: when you press your finger, the air (or water) comes out of the tank - it depends on how the owner cares ;) )
    It is then a development version of the previous sensor, which was used for a very long time and had no valve or rubber cover.

    hi Stanislaw please i have a question; there is a 3 pin connector from the harness on this condensation sensor pin 1-5v black blue. pin2 - sensor ground brown . pin3 24V blue yellow. Pin 3 does not look correct to me ? do you know if 24 v is correct ? i thought that would be the signal back to the ecu. thank you in advance

Topic summary

The discussion revolves around a Mercedes Atego 1323 (1998) displaying the INS 03620 error code, indicating a potential air sensor failure. The vehicle has been operating with air pressure reaching 12 atmospheres, which is above the normal threshold. Responses suggest that the error relates to a condensate sensor located on the air tank, and that the pressure may need adjustment or repair of the dryer system. It is noted that the four-way valve is mechanical, and pressure regulation is achieved through a manual adjustment on the dehumidifier. Additionally, there are mentions of the ABS light activation, likely due to a separate sensor issue. The importance of checking the wiring harness for overheating and ensuring proper maintenance of the condensate sensor is emphasized.
