AdBlue Metering System reset using VCDS

- If you had AdBlue system malfunction message it is possible you did not follow proper procedures to fill your tank. See how to fix AdBlue issue by resetting the metering system and resetting the counter for the miles/km.

Thank you for your post. Had exactly the same scenario on our 2015 TDI Q7 this week. I filled the DEF tanks with 5 gal of DEF and two days later drove a short distance and got a “ Refill AdBlue 1000 miles remaining” warning. Have refilled DEF many times over past 10 years in two TDI Q7s and it has always reset automatically. This time no. Your procedure worked perfectly. I’ll be more careful in the future to do that one minute ignition on without cranking after filling. These are wonderful vehicles but they are complicated and a bit finicky
Do you remember what was your error code?
Have you check for ECU software update? Watch here: czcams.com/video/iEoJ9iakXL8/video.html
Brilliant. My problem is now solved.
God bless you!!! Worked brilliantly 🎉❤
Thank you
Brilliant it worked
Depending on t system, but yes u usually have to carry out an extended road test to allow vehicle to perform an 'SCR Efficiency' test. Providing t fault has bn repaired successfully an scr efficiency test is where t car tests t functionality of t SCR exhaust (ie NOx conversion). Once done successfully t light should go out automatically. I hope this helps
I had this on a 3.0 TDI 2015. The connector pipe on the DEF injector had weeped for years and the white crystals had to be periodically rinsed off with hot water.
I assumed this had got worse and fixed it with JB Weld and large heat shrink tubing, but when testing no adblue came out under running and out put tests and the warning continued to countdown. Reseting the insufficient reductant pressure code just came back and never cleared the countdown message,
DEF fluid was showing 14% in VCDS but I added 10 litres anyway to no avail and did your procedure to no avail. Went for a drive and as soon as the car was warming up the message disappeared so my theory is:
a) It ran out of adblue but expected (calculated) there should be 14% level.
b) The leak caused low pressure reading and it became disabled/locked and your procedure reset it.
c) In addition, the OBDII readiness check was in a failed state until all emissions tests passed on current drive.
Indeed if there is a repeating issue the code will come back.
Браво , и благодарим
Радвам се че съм помогнал. Имайте предвид, че за да се появява нуждата от рестартиране има някъде нещо гнило, но докато не се прояви на 100% така че да се смени правилната част е добре да се ресетва.
Merci
I am glad I could help
thanks
I am glad I saved you a trip to the store … for now 🙂
@bonevchannel what kind of Tester/ Software are you using and how much does it cost?? This VCD !? Thanks 👍🏾
Software is free but it requires the cable. Check different options here:

I have the adblue/DEF fault, no restart in xxx miles. It's topped up to the brim but won't reset, driven it for over 100 miles and still no reset. Do you think this will reset the milage countdown? Thanks
you have to have it checked and see what is the error code and go from there.
Thx. Wondering if this will work for me. I just did the 1st step (IDE004567- resetting SCR tank level). Dash said I had 1600km (1000miles) left on the adblue, but I could only put in about 6L... It had given me the same warning under 3 weeks ago and I put in a full 9.5L (2.5gal) jug in at that point. After topping up today I did the tank level reset. Will see if the low adblue warning comes back. With a full system, I typically can go more than 15,000km before needing to add DEF.
The procedure requires some topping but as it turned out you should be ok even if you do not add AdBlue in if you already have enough in the tank. The last time I did this I did not add any more. Actually topping the AdBlue can be very problematic as it turned out so I would advise not to top to the max. There is a situation I ended up being where I topped it but the system does not detect that the level is going down and will not reset. I had to take the hose to the injector connected to a plastic bottle and drain 1-2 liters of AdBlue so the level in the tank gets lower. Then it reset itself after max 30-50 km.
2 months ago I replaced the NOx sensor which can be also part of the AdBlue Fault error that I was curing with the reset procedure. In another 3000 km if I do not get this warning anymore I will consider it fixed permanently.
But after the 3000km the warning came back so I think mine is related to the reading of the AdBlue lever which in my case always says I have 98-100%. Resetting it worked again 😅
Hi can I make it at home what I need can you help me
VCDS software and VCDS cable, I also used Carista Dongle and software
Hi i refilled my adblue tank and i have the messege about a week lator saying code p208A reductant Pump Control circuit open should i try resetting like you did, or changed def adblue pump ?
I think your is way more specific and you have a pump wiring issue. You should get it fixed.
Hi, I have passat 2016 dsg 190ks and don't have this option reset SRC tank level detection. I bought this car one week before and from then said adblue 0km on dashboard. Car is now full filled but still 0km. Reset SRC lock is available, but I'm not trying because I did not see the first one. Any suggestions??? Tnx
I am not sure why you do not see it. See the first post here: forums.ross-tech.com/index.php?threads/3000/
Didn't work. I still get the p203B error that the level is unplausible
After I changed my pump this happened.
What can I do?
That would suck to have changed the pump and it is the wiring that is the problem. I think you should try to reset it again and then go back to the garage.
Hello!
For me it says: Adblue/DEF: fault. No restart in 600 km.
See owner's manual. If I understand correctly, is this the solution for me as well?
The check engine light is on.
You can definitely try it but if the check engine light is on this means most likely it is not going to work. Still, try it and see what happens. What is the error core from the engine?
@@bonevchannel It only indicates that starting the engine is not possible after 1000 km.
@gaborocsai4789 you have to scan the engine for error codes with a tool
That's not correct. T first reset was for t tank fluid level calibration and you need to have at least a certain amount of DEF fluid to do this. T 2nd function is to reset t mileage count down restarts. Totally duff info 👎
You are absolutely correct about the 2 resets, but that is also what I advise in the video. First top the tank, reset the measuring system, reset the count down. The car should do it after full refill by itself but if it does not for some reason then you want to do it yourself.
Do you know if you have to drive for a while after toping up adblue before the countdown disapears? I have done all these steps, but it does not disapear. No error warnings in vcds.
