Hi. Great video. My Macan, which I believe uses an identical adblue pump to the Q5 is throwing up fault ‘ Pressure sensor for reducing agent implausible signal” As sensor is part of the adblue pump am I correct in assuming a new pump is the only solution or can the sensor be forced to work?
Hi I got the P229F code as the CEL in my AUDI Q5 2011 TDI ,diesel (SLine ) AUTO. I called up AUDI and they told me if it is due to emission fix they will fix it for free. Otherwise they will charge me for diagnostics. Please help do you think emissions fix could be related?
Where could I get the pinouts for the SCR control module? I have similar problem but would like to measure it. Cant find the pumput anywhere. My car is 2019 A5 and the scr module is 4MO 907 355 D (j880 control unit)
A quick question. I have a peugeot boxer 2017.its ran out of adblue and won't start. I've tried refilling but it's just overflowing out like their is a blockage or something.my van is my lifeline and peugeot can't see me for over a week.
Sorry to hear this, unfortunately every scr adblue system is different, we only repair Volkswagen Group vehicles, you may be better off finding a local Peugeot specialist to help you.
@@ctcarsltd8804 hi I have an Audi q5 Quattro 13 plate it had a new adblue heater put in and a new mod - system to the adblue and after a day or 2 the engine light come back and the fault is showing line heater.. can I ask how many heaters dose the adblue system have ? And were should I check next thanks
Damsel in distress: I’ve got a Q5 ‘14 plate and the engine warming light is now on permanently. My garage have attempted a lot of diagnostics and now believe the heater element of the adblue is faulty yet I don’t believe they’ve tested to the depth in this video. They state you can’t replace just the heater element so I need a whole new adblue system at £2.5k plus labour :( do you believe this is correct as your video implies just the heating element was fixed?! All help appreciated, TIA
Hello, thank you for the good video, I have a volkswagen with adblue system, recently I have a recurring fault P203b, problem with the adblue level sensor. What color do you think the lines have and what resistance value should be put? Best regards
@@kristenbekkevold1500 Hello, as the spare parts are not sold in detail, I replaced the heating resistor with another 3 ohm 100w inside the Bocale and welded a 10k ohm resistor outside between the 2 wires of the level sensor and since then everything works perfectly, on the other hand you must not forget to put the adblue every 10000km, to be quiet. That's good luck.
Hi , could you help me some advice , my car is VW passat TDI 2011 ,adblue SCR fault , NOx sensor bank 2 ,P229 poor oxigen detect , no consum of urea,how could I know if sensor is damaged or pump not inject urea , sensor is pretty expensive !. Thanks
It's very hard to do over the internet diagnosis, however the fault code you have supplied is too short. Where did you get that code from? was it a scan tool? if so was there a letter after the P229? if so we would need that to narrow the fault down, if you didn't get the last digit, you will need a better equipt scan tool to pull the last digit.
2 Faults Found: 9567 - NOx Sensor 2 Bank 1 P229F 00 [237] - Implausible Signal MIL ON - Confirmed - Tested Since Memory Clear 15733 - SCR NOx Catalyst Bank 1 P20EE 00 [096] - Efficiency too Low Intermittent - Not Confirmed - Tested Since Memory Clear Readiness: 1 1 0 0 0 that is fault , I've been at dealer , they reset one time , after few hundreds km appear again , no adblue consum . Thanks
When there is a fault with a NOx sensor, there will be no adblue consumption, as adblue (reductant) is there to remove the NOx from the NOx catalyst, if the system cannot measure the NOx then there is no way of knowing if the reductant is working or how much is needed, so the system disables the use of it. The first code is most likely a cause of the second code, cannot be 100% as the vehicle isn't with us. How ever the fault code seems to relate to the rear sensor on the NOx cat not the forward most one. Implausible Signal can be caused by a faulty sensor skewing the signal in a maner the ECU doesn't understand or going open or short circuit, another cause of this fault could be down to a wiring fault (small break in the wire which is intermittently causing an open circuit i.e when going over bumps) or the control module. You will need to eliminate each of these to come to a conclusion. When replacing the NOx sensor's there may be a software update needed which you will need to bear in mind. Also a regeneration would probably need to be carried out to convert all the NOx stored, then If you can see serial data and after a long drive when NOx is produced see if you can see a difference on the sensors, if they are mirroring one another, this might tell you the NOx cat isn't carrying out its function. I see your vehicle is in km, guessing your not in the UK? In reply to your first question "how could I know if sensor is damaged or pump not inject urea" it's pretty clear the pump isn't at fault, the system has just been disabled. As the NOx Sensor 1 hasn't thrown an implausible fault. That's the best advise i can give as you may be able to tell these systems are quite complex, and i have just lightly skimmed on the functionality.
First of all ,thank you for your detailed replay , for sure I should investigate my self the problem , because In service dealer ,sometime I think they not understand how it works the system , it is complicate as you said, but however !!? do you know if there is possibility to "force" inject urea in SCR just for test pump & injector !my car have over 200KKM until now no problem with reductant system , problems appeared after replaced adblue heater tank in the last winter ,I did it my self , everything it was ok after ,carefully checks : wiring ,connections, allover has been cleaned , adblue solution replaced ,system had been work properly until last summer when I got fault adblue refilling (even though more than 1/2 urea tank filled) .After that fully tank filled, reset fault but since that time system does not work .What could you recommend me ? I think I should investigate all wirings,pump, pipe from pump to injector ,injector it self, clean whole system and only after that if still same issues I'll replace NOx sensor , as I said ,it is so expensive ! and it is needed resoftware !Thank you and await your opinion .
You want to be looking at the fault codes first and repair them, which in your case is a NOx Sensor fault, Check the wiring from NOx sensor to control module if all ok then you need to look at serial data to see what the NOx sensor is doing, ignore the adblue system until this fault is repaired first, then you will most likely find the adblue will start to work after a regeneration if needed. If the adblue fault still is present with no fault codes, then i would be looking at that system, however for the adblue system to not work there normally is a fault code relating to that.
Hi there Thanks for your video I have a fault code p20BD00 I was told it is reductant heater control circuit B Do you have to take the bumper off and drop the adblue tank to get to the heater . In your video it don't look like you do Thanks lee And where exactly are you based

What is the issue for P21CA fault?
Where could I get the pinouts for the SCR control module?
I have similar problem but would like to measure it. Cant find the pumput anywhere.
My car is 2019 A5 and the scr module is 4MO 907 355 D (j880 control unit)
What's the part number for the heater?
Is there anyway adblue can get into fuel tank when filled my diesel today i could smell ammonia????
P204B, -11c tempeture. Good ol Def flush and refill will fix or do you think pump has gone bad?
Hi can you tell me where the def after treatment reduction control module is located in 2011 q7
Thank you so much more
