Peugeot Citroen - Supplement AdBlue in the PSA group control UREA

A friend in Berlingo 1.6hdi, with the nox probe error, probably the performance of the system decided to burn his car on the highway. Calm the second week, but only the check engine without the urea control informed about the problem.

Hi,
I drive the highway every day and unfortunately it didn't help.

Berlingo 3 - 2017 - 1.6HDI - 85 thousand - similar problem, also codes: U029D, P2200 - I used Car Scanner and SDPROG - but unfortunately I cannot delete these errors. Of course, every now and then the adventures with the message "Fault in the exhaust gas treatment system" and the limit of 1100 km, basically for about a year, have been appearing and disappearing. In the ASO in February, cleaning of the Adblue injection. Now I have these two bugs and wonder what to do next? Will I visit an authorized dealer again? Is an attempt to clean the NOx-A sensor as described here?

A visit to the Dealership - last week - replacement of the NOx-A probe - helped. I also added TUNAP. Today error P20E8 - I deleted it for now. I wonder what will happen next. I'm slowly fed up and I'm seriously thinking about changing a car - never again ADBLUE !!!

Well, the P20E8 error returns despite the deletion, interestingly at the same moment, I drove maybe 5km and came back today.

Thanks, waiting for information.

I drove 400 km today and the error has not returned. In my case, replacing the NOx probe helped with the P2204 error. I was able to buy it on OLX for PLN 730 with shipment new, original Continental. Change by yourself 30 minutes. I am glad that this problem has been fixed.

Hello gentlemen. I am the owner of a Toyota Proace (twin Peugeot Jumpy). Unfortunately, after the "replacement" of the AdBlue tank, the error returned after driving about 80 km. The question is whether they only deleted the error, because they did not want to give any receipts (the replacement was at their expense). The question of whether the Laxia Diagbox application will approach Toyota, maybe one of the users had a similar problem.

If this helps someone, I was probably able to locate the direct cause of the P20E8 error (low urea pressure). The previous speakers mentioned that they tested the pump "briefly" and in my case the pump also works with this connection. I delved into the topic a bit and prepared a "test kit" connecting, apart from the pump itself, also a pressure sensor and a solenoid (shut-off solenoid valve). Unfortunately, despite the fact that the pressure appears physically after switching on the set, the voltage does not change at the output of the pressure sensor, remaining at a constant value of 0.420 V - I have a good reason to believe that this is the whole fault with this module. The sensor number is 12678102. Connection: black - ground, red - 5V, yellow - OUT. The sensor itself looks like Chinese similar to MAP sensors, which also experience similar failures. The funniest thing is that you cannot buy this sensor, but you can try to look for something similar, or if someone has a minimal idea - cheat the driver with a properly selected resistor divider, which I will check soon. I hope that this information will be helpful, because I had to search a lot myself through the maze of "add TUNAP", "replace the tank" tips, which do not solve the problem anyway.

The pressure sensor tracked down a company from Italy. They manufacture subassemblies for medical devices. I tried to make contact but no response. Also no spare parts, although these sensors are very poor and they sit down most often.

The only hope in the Chinese. Motors for this pump are already available - someone has already looked abroad . However, the idea with a resistor divider is wrong, it will not work - the controller must have confirmation of the pressure value because the pump kills the pressure when it drops. Knowing the exact operating range of this sensor, you could order something similar on Ali and install it even in a different place (e.g. on the cable). Honestly, the PSA policy is starting to frighten me - I think they want to be the equivalent of Apple in the automotive industry, only cars are not very luxurious.

Does anyone have a bearing on the pump motor?

Hello, as if what buys damaged modules from Adblue. I am asking for info at PW, if someone has damaged electronics from the adblue tank, I will buy it.

Do you repair pumps?

I don't play with others

In the sense of the pump itself

Do you have anything to trade?

Do you need a pump? I can sell something with this

I ordered a stimulant. If it doesn't work, I'll take it from you.
It's a pity it didn't work out earlier.

Question. Pump replacement and nox system test.
After the tests, the info pops up that the urea injector is not efficient.
The question of injection or pump? I choose the injection because I had a different module before and the pressure was low during the test.
Any suggestions?

Hello. The patient opel combo e 1.5 bluehdi

Hello.
I will share my observations with the p20e8 error in the cactus 1.6 HDi from 2014.
Well
Not from the pear, the urea light and the engine light came on. And since I had it before and the reason was the low level of adblue, I immediately went to refill the liquid. After pouring about 6 liters into the tank, I thought that the matter was settled. Unfortunately, however, the controls did not go out. So I connected something like that purchased on the Allegro to the OBD and did a test via the cell phone. I got an error p20e8, i.e. too low urea pressure. I deleted errors and the lights went out. After driving about 10 km, the error returned and it was no use resetting the error. After a few dozen kilometers, the error returned.
After the diagnosis, the mechanic stated that either the replacement of the tank with the urea dosing pump costs 4,000 or we throw away euro6 and I have peace forever. Of course, due to the fact that I am Polish, I decided to go for option 2. We agreed for a week. In the meantime, however, I read to add the tuneup 986 discs to the adblue, which I bought on the Allegro for PLN 120. At the beginning I poured the preparation for 20 liters of adblue, although the cactus tank contains a maximum of 14 liters. Unfortunately, during the first two days nothing happened. After clearing the error, it popped up again. So I added the preparation for another 10 liters of adblue and the next day the lights went out ...
Just. Currently, the car has traveled about 700 km and the error has not returned. For now I am a thousand ahead, but maybe even 4 thousand because euro6 is left ?
This is my story with the urea dosing error.
Good luck

Sometimes the adblue injector is clogged by old fluid. Perhaps this agent and its laxative properties were washed by the injection and maybe the pump?

The system would seem simple, it should work fine from time to time inject a little adblue. But the quality of workmanship is terrible, and the prices for a set from outer space. When buying a new car, you have to ask about the prices of some components and this is what you should suggest when buying. Buses that are supposed to spin km are wandering around the servos And this is egr, or wttry or adblue. Half the trouble if the warranty is under the warranty, although some posts show that they postpone the replacement for new parts as long as possible, which would end the warranty.

Never fill adblue through the dispenser at the gas station. Only by hand like washer fluid. Even in the instruction manual, refueling by the distributor is prohibited.

You see, we pour out of a stick into the trucks and somehow drive, 500,000 and more. And Adblue systems don't sit down that often.

It is a different capacity of the tank and you still need to know that you need to pour only to deflect the gun and no more. And it happens that drivers pour full into the traffic jam and this is the beginning of problems with the system.

error P20EE 00 - I deleted it, the system started


So how did the problem end?
What was the cause of this P20EE 00 error

I have been struggling with this topic for over two years P20EE 00.

The problem occurs at subzero temperatures. Evident decrease in system performance.

My way to learn the topic is to remove the error, reinitialize the system. You need to dose a double dose of the preparation for urea crystallization. The problem occurs, but less often, longer driving in low frost also helps.

Generally, I do not let the car stand in frost, (- 10 adblue freezes) if I have a bug, I remove it, activate the system and give it a chance to work.

The winter period is over and the problem is gone. All summer even one negative signal that something is wrong.

I had the tank and injector replaced. In my case, a new probe has yet to be installed to exclude it.

Peugeot 2008 - adblue low pressure error. A little bit of smear how it works, etc. Good pump, first suspicions about the pressure sensor. 4bar all the time in the diagbox. But as it turns out, this is a programmed output value that has nothing to do with reality. In addition, the engine controller starts communication with the adblue module when it needs it. So right after turning the ignition on for several dozen seconds and in conditions where urea can be injected. So for nothing to bury in this module under the car with the ignition on. As I figured it out, I was able to simulate different pressure values, but it did not start the pump or generate another error. In the case of this 2008, I replaced the entire tank with a properly used one (merchant's request). My diagnosis is damage to the pump control, but it does not have to be an electrical fault. The electronics looked good and the measurements I could take were ok. In an efficient system, as soon as the engine reaches the set temperature, the deaeration phase takes place. Then the pump turns on and the pressure starts to increase. I will have a berlingo with the same problem soon. We'll see what comes out there. As for me, the simplest possible test is missing from the diagnosis level, i.e. unconditional activation of the adblue pump. These pressure build-up tests, etc., etc., are an asshole. Something is going on, but who knows what.

What do you mean by "reinitializing the system"?
do you have any other errors with P20EE 00?
For me, this code appeared just recently at the first frost (only this code without other errors)
I have a 208 1.6 bluehdi from 2017
A month ago, I filled the tank with 10 liters of original fluid (PSA bubble). I was still wondering if the fluid does not keep the parameters of it ..
Tomorrow, maybe I will test the DB on a warm engine and see the parameters.
I was looking on other forums and at this link the guests worked it out great, but mainly the problem of low pressure

The system works as the engine warms up, so only then shows the appropriate pressure and parameters, especially pressure - 4 bars is no pressure, but it shows so on a cold engine. The system loads only when the catalyst reaches a minimum of 175 degrees Celsius and then you need to check all parameters.
Look at the link - the guests did a great job of it

https://www.peugeotforums.com/threads/p20e8-fault-code-and-urea-tank.327132/page-37

today I did a test. I deleted the error and it did not pop up anymore.
I flew through the DB and it looks like everything is working properly (parameters OK) - everything works, pressure is ok, temperature shows, injects urea,).
Maybe because the spring weather is 10 plus or maybe because I added a little more Tunapa.
We will see it fall below 0.
I will try to test it in the cold when it comes - we will see what parameters it will show.

Hello,
unfortunately, like most PSA users, I have a problem with the SCR system.

First symptoms:
after buying the car this year, after driving about 1500 km, the UREA message, add urea (the car will be blocked after 3000 km). I think OK, I'm going to add AdBlue ... Unfortunately, after opening the cap, I saw a mirror of the liquid (I tried to pour AdBlue, I ended up refilling 0.3 liters.

Of course, the bug did not go away, so I did the procedure from the first thread.
Being aware that this is not the solution, but the messages are gone and everything worked fine.

Unfortunately, recently UREA + SERVICE errors (damage to the exhaust gas treatment system) appeared after a while ENGINE (engine failure ...).
And countdown of the counter (the car will be blocked in 1100 km)

After connecting the diagbox, errors appeared ... P20E8 00 (urea fluid pressure) and U059F 81 (Communication fault with the NOx system).
Currently, errors have been deleted and messages have disappeared, but nevertheless the problem is bothering me.

I have carried out all the available tests in diagbox regarding the DENOX system. what i found:
- after the engine is warmed up - the pressure in the NOx system is about 5.6 bar
- Bleeding - error too fast bleeding
- unfortunately, I did not have the opportunity (yet) to disconnect the injector and verify that it actually injects urea during the test, but I ran this test and you can hear both the pump (it builds pressure) and the injector can be heard.

Unfortunately, the error I encountered is the lack of information about the amount of AdBlue (as if the level sensor did not work).
Has anyone had a similar case ??

Additional and very important question ...
If this error (UREA + SERVICE + ENGINE) reappears, then the number of kilometers to be blocked will be 1100 km, or is the clock somewhere in the memory still counting these kilometers? and it may happen that another error will tell me that there are 200 km left to block ???

Thank you in advance for the hint.

Thank you in advance for the hint.

If the car "catches" an error, e.g. P20E8, the counter starts to tick from 1100 km. In my case, I drove up to 30 km and warned against engine immobilization, after deleting the error and possibly catching another error, the car starts counting again from 1100 km. So cool.
