[Solved] MAN TGX 18.440 - GDK / PDF 05018-13 - Fault transition from passive to active k

Hello,

I have an error as above, from what I found on the forum, it means a problem with the Adblue heating valve, if I'm wrong, please correct me. FMI 13? I don't know exactly that, what does it mean? Open?

The problem, however, is that the error goes from active to passive, then from passive to active several times per, say, a minute.

And my question, is this solenoid damaged just like that? Before I replace it, I want to make sure. After removing the ankle from it, I have error 05019-13, which means a break in communication, so there is probably no problem in the beam.

Of course, for this we have a flashing MIL indicator and no refrigerant charging. Yesterday, while driving, the MIL light went out, the error was also okay, after turning off the car and restarting the error again, the error will crash all the time.

Maybe someone was working on a case

On the vehicle frame, under the aluminum platform.

So there is nothing to combine? replacement will do the trick?

Or maybe check the valve resistance and cable continuity first.

Check how the colleague above the continuity of the electric cable is usually damaged until it is on the frame, but look for just after the plug.

And if there was a problem with the installation, would it not be an error about the lack of connectivity, i.e. the same as when the plug was unplugged?

And what's the problem to check 2 braided electrical wires?
99% of the cases with this valve are these two conductors, but there is still 1% left.

Ok, tomorrow I will tear the cable cover and see it, I also think it's a cable because the error pops up like crazy. What should be the resistance across the valve?

Pin description.

Hello,
Well, the valve is 34ohm, so it works.

The current in the block reaching the valve is 21.4V

In your case, I do not know if we are going in the right direction because the error you give does not say about an electrical damage. "05018 - 13 - Adblue heating valve open, temperature higher than expected" either the valve does not work or something wrong with the temperature sensor.

This is why I wrote earlier that there is another error after disconnecting the plug (05019-13).

After connecting the new valve to "DRY", i.e. only the electric plug, the error is also active. (05018-13)

If we are talking about a temperature sensor, which one?

In the adblue tank.

I understand that in order to get to it, in case of what, I have to rip the tank open?

Will I be able to check what values it shows after connecting to the computer? I will diagnose Delphim

First you should check delphi parameters should get it,

Ehhh .... you get lost and very ...
5018 is an AdBlue dosing module and not a heating valve, therefore probably Euro 5

Yes, Euro 5, 2008.

Realizes it's a dispense module, but then what about the FMI 13?

What do you suggest?

First of all, I suggest checking the wiring and the dispenser itself.
FMI 13 is a wire breakage and / or its (or dispenser) short circuit to ground.
Personally, I encountered a fault where it occurred variously and cyclically, the wires were ok dispenser ok - the reason was the electronics in the pump module.

So, after connecting the computer, I just have a description as indicated by the colleague above. Surprisingly, after an attempt to start the pump, the pump starts and builds up pressure, but due to an active error that cannot be removed, the dosing stops after a while.

Break or short to ground ... It looks like the module bone beam will be checked?

By writing

- dispenser or pump? because so far I thought that we have a pump in the module and the injection at the exhaust? I know, maybe it's a stupid and amateur question, but from the whole system, so far I have been dealing with the fight with the pump, which is located in the entire module behind the cabin and with the device at the exhaust, which is, as far as I know, injection?

Pin 26 wire 90133 with pin 27 wire 90134.

Your version is Euro 5, because Euro 6 has Emitec and Bosch and each of them is a different system ... but to the point, this "can" behind the cabin is a pump module with a pump, sensors, filters, etc. and it sends adblue under pressure to the "dosing module, colloquially a dispenser which is an electrically controlled valve from which the adblue goes to the nozzle (not to be confused with the injector because the injector is Euro 6 Bosch)
Your problem is the dosing module, i.e. the dispenser, it is exactly the element that is in the pictures at your colleague above and as he gave you to check, you have the wires from him that go to the pump module, it is possible that they are worn or shorted, it is also possible that the dispenser itself is damaged.

I checked the dispenser, and the voltage on the 8.8V plug and the injection resistance is - NOTHING. Zero response to connecting the meter.

Is the voltage on the wires correct?

An interesting fact is that a week ago on Friday, after starting from the parking lot, the errors disappeared and the pump started and worked for 4-5 hours of driving. After the weekend and the departure, the errors reappeared ...

Hello
The injector resistance should be around 16 ohms. In my opinion, something is not connected in the injector and hence the problem.

As I remember correctly it should be 12 V.

You have everything in the documentation included, so why are you asking?
The colleague above is mistaken with this voltage, you can burn the valve coil. This coil is controlled by the PWN signal.

That's right, everything is included in your attachment, I only looked after writing the post.

So there is nothing left for me to replace the dispenser. however, before I buy it, I'll swap it from a different mana and make sure it's it and let you know

You can replace the valve itself, it will be cheaper. Ask at INTERCARS.

And the problem is solved :)

The cause of this error and inoperability of the system was a damaged dosing valve / injection, which can be seen in the attached photo by a colleague above :)

In my case, the voltage on the harness was 8.8V, while the resistance of the valve / injection itself was 0 ohms and the resistance on the new injection was 14ohm. After replacing, the GDK / PDF 05018-13 error became passive immediately and the pump started after the car was started again.

I can only confirm what my colleague suggested above, it makes no sense to buy the entire dispensing module, especially since it is an element that can be dismantled and cleaned (I did it in February). The valve itself costs about PLN 500 gross, and the module is about PLN 1000 gross.

When replacing it, I suggest rinsing the module with hot water after removing the injector, especially since the system does not work for a long time, a small crystal is made in the module itself, so it is worth rinsing :)


Thanks to everyone for your help
