Good evening gentlemen I've been searching the internet for a few hours and found this place I hope I can get some help. A brief description of the case is as follows. Citroen Jumper year 2019, 2.0 BlueHDI 163KM engine - factory-built semi-integrated motorhome. The car was bought new in a showroom in Poland - I am the second owner. I've had the car for 56,000 miles and it's been great so far. Currently the mileage is 71.5 thousand km. From November to almost the end of January this year. the car was stored in a heated hall and was not used. Before inserting for wintering, information about the low level of adblue was displayed to me, but I decided to supplement it before the next trip, i.e. in about 3 months. When I picked up the car, it didn't want to start, but I managed to get the cables. I quickly replaced the car battery and that same evening we set out on a trip to Morocco. Of course, I refueled adblue to the full (10 liters came in) and we set off on the road. After about 700 km, the message "check the adblue system in the service - see the manual" was displayed on the board. I am very stressed by such messages but the car was driving normally so I continued driving. In about 50 km, another message "check engine in service" came out. I panicked a bit but nothing happened so I kept going. We got to our family in Belgium and there I managed to get to the equivalent of NorAuto and a nice gentleman connected to the computer on the left side below the steering wheel, erased the errors and wished us nice holidays. I breathed a sigh of relief - nothing was on the board, so we happily drove on. The luck didn't last more than 10 minutes as the errors popped up again. Since then, i.e. for 4 days, we have traveled about 1,600 km and the car is driving normally, but I am more and more stressed whether to continue the journey .... In France, out of curiosity, I added adblue and it came in less than 2 liters after driving 2,000 km, so it usually takes it. I found a description of a similar situation on the web, but nowhere was it described in such detail and detail as here. The advice was different - they wrote not to tighten the adblue plug, etc., but these treatments did not help. The only suggested solution was to program adblue from the software and solve this problem once and for all. I contacted various motorhome friends but most of them have a 2.3 ducato engine and there are no such problems, although one of my colleagues informed me that one of the people at the campsite has the same car as me only from 2020 and had the same problem. The ASO service requested about PLN 8,500,000 for the repair ... Finally, some software specialist for PLN 1,600 took care of the matter, the car drives and everyone is happy. I am worried about the information that other users have given about limiting the range of the car. So far I do not have such a message, but I am 2,500,000 km from home and I have about 7,000 km ahead of me in the original plan ... I looked through your entries and you can see that you know what you are writing about, especially the founder of the topic who put a lot of time and work in this thread. I like cars but I have no idea how to repair them and I can't imagine removing the tank myself, etc., apart from the lack of equipment, I simply wouldn't be able to check even the simplest things you write about ... I can't imagine taking the car to Poland on a tow truck because AC covers towing up to 500 km .... Can anyone advise a sensible solution?
"blue" circuit heating the urea accumulator - 212.0 ? is the value correct?
Strange thing now I checked again because I have two tanks the same. And now on the blue circuit I have 16.0 ? on one tank and 42.0 ? on the other tank !!!!!!!!!!!!!!!!!!!!!!!!!!! And I would bet that it was 212.0 ? Then I was measuring in the summer when it was hot and now in the winter so maybe it depends on the outside temperature? Now I'm crazy to the max.
Hello, I had a problem with the tank in c4 Picasso II 2.0 hdi error "urea pressure" and range 1100km. Today I removed it and it turned out that the temperature sensor on the tank heater plate is false (yellow wires) had a resistance of 353 ohms. I installed a new 10kohm thermistor in a 25cm hose. and pushed it through the beam hole in the vicinity of this heater in the bottom of the tank so as not to play in cutting. To be honest, I don't know how to go about disassembling this tank and the lower part of the dragon with the heater and then gluing it to make it tight. After replacing this thermistor everything works fine. I do not know what technique you use to dismantle and glue the tank, maybe someone will share and throw some photos of the dismantled tank. To be honest, it was thanks to this information from the post that I dealt with it without any problems because what the computer showed was a bunch of nonsense. Thank you and best regards.

I will try to answer your questions briefly and to the point. Please don't even try to get inside the tank because it doesn't make sense and nothing good will come of it. I made such an attempt and ended up buying a used tank on Allegro. When driving a car, the tank is subject to quite strong stresses, the overflowing urea during braking hits the walls of the tank. I haven't found a glue that can glue the tank properly. The only method is welding with ABS plastic. It doesn't make any sense. For PLN 200 - 300 you will buy a damaged tank for Allegro and with a high degree of probability this lower part will be functional and after the problem. That's what I did and it's been fine for almost two years now. The material from which the tank is made is ABS plastic, very durable but difficult to glue. To get to the part you want, you first need to split the tank in half, and only then will you get to the next one, let's call it the box in which the sensor is located. It has very complex shapes and contains delicate parts and it is almost a miracle to cut open this can without damaging these elements. Re-gluing is a nightmare because this part is made of even more difficult to glue material. In short, please don't even try! What you did is sufficient in my opinion and the tank should be treated as repaired. Maybe with very strong frosts there will be some error, but I don't think so.
Gentlemen, here's the situation: January 2023 negative temperatures, "low pressure" error. I filled up adble plus tunap 986 twice or maybe even three times the recommended portion. Every now and then I cleared the adblue error. And today, after about 2000 - 2500 km, since the error first appeared, at a temperature of plus 10 degrees outside for the first time, the error disappeared by itself and will not appear for about 50 km. I drove so much today. Any explanation for this situation, is it Tunap or higher temperature or something else what do you think?
Is it possible to repair or replace the level sensor in the adblue tank without replacing the entire tank. When the live data on diagbox says the tank is empty when in fact it is full.
The sensor itself cannot be replaced because it is located in a non-demountable part of the tank, but you can cheat the computer. This is covered earlier in this thread. The matter is very simple.
Conclusion with a faulty level sensor and no possibility of repair, because it is located in a non-dismountable part of the tank, the sensor should be disconnected and the voltage should be applied to the cube, e.g. +4.5V, which will be read by the AdBlue system computer that there is a high level of urea!! And after the problem!! Just remember to top up the urea on time.
>>20423065 Hello, I have 10 units of Peugeot pumps, I own a 3008 from 1916, with a mileage of 45,000, I replaced the tank under warranty after three years and 40,000 km, the problem has returned. Due to the significant cost of the new tank, I am trying to solve the problem myself. I need data in what range the resistances of the heaters in the pump module should be. Green, yellow, blue, white circuits. I measured these resistances on my pump modules and the readings for these circuits on each module are different
>>19585986 Waste of time trying to fix this pump. As if man creates and man should repair. But as of today, the cost outweighs a possible attempt at regeneration. Turn off adblue and after the topic.
Added after 8 [minutes]:
The consequences of disabling adblue are NONE. No one in Poland or at the review is able to check the SCR system. They do not have the equipment for this type of analysis. Even if etc had it, the whole check would be based on a neighbor's report that you turned off adblue. After switching off, the emission standard does not change. The whole business is to sell NOX probes, pump-tanks, etc. The SCR system can kneel in one-year-old Mercedes and the repair costs tens of thousands. A properly turned off adblue system does not change anything in the car and it cannot be detected. Paranoia is spreading in the network that after turning off adblue you will end up in Siberia ))) If we explore the operation of the SCR system, it is not so easy to diagnose it, let alone detect its shutdown As for the regeneration of the pump and its resurrection, true respect for the author of the post. I can help with any software.
I asked in technical terms, dpf ... other of this type.
I had a little acid in the service, I took the car to repair the power steering and during the acceptance and attempt to start I was greeted by a not very pleasant message "something about a critical error of the engine and ADblue".
The workshop that I brought such a car, after a stormy exchange of opinions, an electrician came to diagnose, asked him to leave the workshop and after 10 minutes he came back, he said it was ok and the problem was a non-connecting cube at the controller. When I asked if he accidentally programmed Adblue, he denied it and said that it would take him about an hour.
Since then, there is no critical message, the low fluid level indicator does not light up, and I drive a lot to check it, recently I refueled under the cap and after a few refuelings I want to check if it has gone down.
Programming takes a few seconds to a dozen or so, sometimes an hour, but it depends on the method of flashing the ECU - if it was done by an independent Tuner on the spot. So he wasn't waiting for a "file" from the other end of Poland What car are we talking about, give the year, capacity, how many kw?
