EDC 3822-04
INST 8135-04

Someone can do it? what and how

Not connected beam is also connected to EDC. After all, you have the wire number, which is difficult to check where it leads? Have you checked the thick cable from the plug that goes down near the frame?

uhr · Answer

The rest of it has already connected to man but there is another problem.
INST 8135-04
EDC 3822-04
DIAG 2061-08

It looks like a damaged probe in the Adblue tank or cable, but when connected to another car, it's still the same.
After turning the ignition switch on, you lift a little more after a while and suddenly fall to the bottom, whether on your sensor and cable or on another mana the same.
The beam goes from the sensor to the vicinity of the tank and another connector and then where does it go?
I am asking for a hint

kakibara · Answer

The beam goes from the sensor to the vicinity of the tank and another connector and then where does it go? - unscrew 4 screws from the bottom of the tank or cut them, check if the probe is not completely in the adblue, you have a plug behind the tank, climb up to the orange connector, check that the pins are not green, you have 6 cables with numbers 3 to pump 3 on the side frame and we drive the whole beam, most of the problem probe plus this connector on the boiler.

uhr · Answer

The problem is that, as I wrote above, the probe and cable to connect to the tank is ok.
Then this cable goes where only to the adblue box? is it a separate bundle or woven into another one? to keep checking her.

It is worth to write what engine is in your vehicles. Euro 4, 5, 6 ... are different systems and under the same vehicle name. If you have Euro 6 .... you shoot in the dark, the system is so extensive that no one through the forum will help and without professionalism the car will not work: /.

kakibara · Answer

I have over 600 euros at my company, 6 runs over 340,000 km, when they arrived we thought that there would be problems, and it turns out that the system is refined - there are two problems with the system blocked return line - we rinse the system with water and a damaged pump - for replacement, this is the most common lambda probe several times on the muffler on the right, there is never a sensor and there are 2 times more than in Euro 5, filters are not exchanged in Euro 6.
The author's car is euro 5.

sebotrucker · Answer

I had the same problem as you. I have a rotting orange cube above the fuel tank. And exactly one pin with the number probably 195. But the adblue status was normal. I also had a problem with the fact that once it showed the state and once not and here the culprit was the sonar at the bottom of the tank. But then the errors were not shown after the message to add fluid. Check with the meter if you have a transition from the orange cube to the sonar, in my opinion there will be a problem.

uhr · Answer

Adblue coolant valve 5019 What is he responsible for? Where is the valve located?

kakibara · Answer

As I wrote to you, the wiring harness to be checked, i.e. the whole - and this small diameter pipe leads to the valve from the height of the half of the right rear mudguard - the fluid valve is located on the back of the pump - screwed on 3 m8 screws.
You had to generate this error yourself - the ones given at the top say something else. Look for a damaged wire from the plug to the T-piece connecting the two pipes.

uhr · Answer

It is another man that has gone and is making such a mistake

Stamina - Land · Answer

Hello Uhr. I have exactly the same problem. AdBlue level zero, power limited and I can't connect Texa with AdBlue. Error codes exactly the same as yours. Tell me what did you do to connect? I will add that the injector beam flooded the computer with oil, of course I already installed a new one, the electronics was dismantled and washed inside. The problem is still with AdBlue and the diagnosis by Texa that cannot be connected. Help ...

is the most common lambda probe on the muffler on the right several times, Hello, I have a question for a friend. Due to the fact that tgx E6 constantly displays me an EDC error 3855-05 (lambda probe system) and I replaced one probe some time ago (probably from the muffler on the left, because for the password the lambda probe was issued to me in intercars and these numbers matched) and then the same error crashes, I have a question. There are probably 3 probes around the top turbine, I remember. Is only one of them lambda and the others are just ordinary temperature or maybe two or three lambda ?? I think I mentioned not this probe, but they gave it to me from the catalog, they didn't say anything about the others,

kakibara · Answer

The lambda probe is one - you have it screwed under the turbine on the pipe that goes out into the muffler - it is the one which is finished with the plug itself - fastened on the right side of the engine block.
The error says about the wiring so maybe head in this direction - plus probe calibration although it used to be exchanged very often - but with another error number I never calibrated it always worked immediately.

maciej.wojta · Answer

Thanks Kakibara.
I just exchanged this probe and then shorted to ground.
I need to look for a problem in the installation.

I still have a question, by the way, error "incorrect adble temperature"

Do you replace the entire dragon in the tank (probably with a float), it has a fluid temperature sensor in it?
ASO claims that they do not sell the sensor separately and you need to replace the whole.

kakibara · Answer

Tomorrow I look in the system or you can buy something separately from the installation - I will never delve into it.
When it comes to replacing the float, I always replace the whole one.
As for the problem with the probe, I have never had a problem personally with the wiring, the replacement has always helped and it was bad news.

Dariusz G. · Answer

Hello,
Gentlemen, I would like to hook up to the topic. I also struggle with the lambda probe error as described by my friend maciej.wojta
The probe replaced and nothing changed. I would like to know if you have dealt with this problem?
greetings

kakibara · Answer

What man, what error of this probe, what additional errors, probe and what happens with the car?

Dariusz G. · Answer

He described the same as above. Man tgx e6 440, 14 error appears sporadically 3855 fmi5. Recently jumped out after firing the hangman, but it was inactive. The probe was replaced. The nox was in good working order. The car flies to Sweden, and there the most often the driver lights up under the hills Ad-blue downloads normally, tests pass correctly From what I knew and I see that the return line and pump have been changed. Currently we have a problem with visco. After its replacement, visco works for a very long time, almost all the time at low speed. I was interested in the parameters of the probe, because on a cold engine it shows a voltage of 0V, a resistance of 1890ohm, and a temperature of 577C, where the exhaust gas has, for example, a temperature of 50C.

This started to happen after replacing the pump in the adblue dispenser. I don't show the adblue level. The funniest thing is that the errors ignite after turning on the ignition, the car will start, it takes 3-5 minutes and everything returns to normal, the adblue level begins to show. Has anyone ever had such a case? I don't know what to do anymore ...

kakibara · Answer

Cable on the tank, orange plug, adblu level sensor from the bottom of the tank, put in a drink with the plug to the pump

hehe_2288 · Answer

This is where I started, nothing helped. I checked the meter and there is a passage on all cables in this plug

TruckElectronica · Answer

Detach the Nox_a will be an error from him but watch if the adblue level will show all the time.

hehe_2288 · Answer

Do you think it's NOX's fault?

TruckElectronica · Answer

It is enough to disrupt the can bus, and there is nox on it, the adblue level sensor is one of the possibilities that I have already encountered, it will not necessarily be here, but ...

hehe_2288 · Answer

It's strange that it happened after replacing the adblue pump ... Maybe pure coincidence.
Does the beam from the adblue level sensor enter the adblue dispenser? I can't find a schematic anywhere.

Puk, what am I on the road with a German and I do not have much opportunity to check, but it looks like, for example, the relay in the dispenser has failed because when it works, it works all the time until I turn off the car and there is a relay in the pump, but I do not know what for

The worst thing is that I don't have anyone to borrow and check the entire module from

TruckElectronica · Answer

There is a diagram here on the forum, look for it

kakibara · Answer

You have a problem with the connection of electric wires, it was also a good idea to check the fuses.

hehe_2288 · Answer

Hello. I checked the installations today, everything is ok. It started working. I did a test drive and everything was ok. I turned off the car, after 3-4 minutes I turn on the ignition and it does not work again. I turned off the ignition and turned it on again and it started to work again (I didn't move anything or I didn't touch anything, just turning the key) ... I've had enough, does anyone else have any idea?
