PEUGEOT BOXER III - Repair of the AdBlue tank PEUGEOT BOXER III, CITROEN JUMPER

>>21461118 .

Colleague mlody300 is right. You need to disconnect this faulty thermistor on the "yellow-yellow" and attach a resistor in its place, because when you get to the complete failure of this thermistor it can make an open circuit (break in the circuit) and the error will return. You cannot have this faulty thermistor in the circuit now.

>>21426633 Good afternoon, may I ask where you purchased the 2x2 mm orings mentioned? Thank you.

I bought all the orings on allegro from one seller - he has a very large selection. I don't know if I can give you the contact details here. Contact me on priv and I will send you the link.

@Pablo_Pablo Good day, may I ask where you purchased the 2x2 mm orings mentioned? Thank you.

@patrikskrizovsky I sent a pw. with a link.

Good morning to start with really a piece of work for this material is very useful !!! my problem boxer 2017 2.0 bluehdi no errors just counting down the kilometres tank full to full and kilometres falling as if there was no urea light adblue light was on all the time and still is unfortunately I can not say what was before because I bought the van six months ago and always some problems until I changed the ecu bsi and meter and as far as I know in my old ecu was knocked out adblue and I do not know for what reason .... probably just because of what is now.... has anyone had this problem ? And is it possible to work around this without replacing the tank or should I just order a second hand one and change it? And is it necessary to adapt the tank after changing it ? Thank you for any answer Greetings

Maybe a filling procedure needs to be carried out,or a tank reset? Or maybe the float in the tank is not working , after replacement no adaptation needed.

I just have a problem with this because I get some kind of error when I try to do a computer procedure I bought a Launch x431 a few weeks ago and I don't know what's wrong with this connection , but the tank I bought used from a younger boxer 2022 today is supposed to arrive tomorrow I'll move it and let you know thank you for your answer

I'm also having trouble with low adbue pressure, peugeot 508 2.0bluehdi, I'm betting on a thermistor failure on the yellow wires because in the diagbox the urea temperature is 0 all the time and doesn't change, despite the much higher ambient temperature. I'm going to cut the wires and solder a new thermistor and then run it inside the tank through the hole under the motherboard. Will a 3.3kOhm NTC thermistor be correct?

Hi Danio12344 what engine controller do you have. I have a Ducato 21r at my place with ecu MD1CS069 and I can't do the Adblue system reset. I have the Launch original with the current update and lime so far. It has already counted down my kilometres to zero and the car will not start. I managed to do some reset firing after that it fired up but jumped 50 km to the end. Someone reset the adblue in this ecu and with what tool.
Texa doesn't get it going either.
I warn the SGW gate I have bypassed the errors normally clears.

The thermistor on the yellow wires measures the temperature of the heater.
Unplug the yellow plug and measure the resistance and you will know if it is faulty, usually when faulty it has a low resistance around 300 ohms.
If it is working properly the resistance will be around 10k.
If it is faulty, cut the wires, solder the thermistor and push it as far as you can through the hole and it will be ok.

>>21542794 At my place the controller sits Delphi, I don't have the number unfortunately.... I managed to acquire a used, but from a fairly new van, AdBlue tank and everything settled down by itself. I suspect that the original AdBlue tank had a banged up fluid level sensor that was impossible to get to. I recommend buying a second-hand one and replacing it - peace of mind.

Helped. Thermistor 10k soldered, has the previous one was 285ohm. Everything has been working for a few days now. Thanks mlody300, mako122 and others for creating and continuing this thread.

I did according to the advice, had 300 ohm on the circuit, soldered a new thermistor and since 1500 km there is no trace of the error. A big thank you to the author of the tutorial!!! I bought the gaskets as a spare, I can resell, jbc prv.

Hello, I have a problem with the AdBlue pump on a 2018 Citroën C4 Pixasso. I completely disassembled the pump unit and resealed it. We checked the circuit board and found that D341 has a short circuit. What type of diode is this? And what effect does this have on my system? The error code is P20E8: Urea pressure too low.
