If I was you I would kick up a stink.

I have a 308 66plate 36k miles, last month had my adblue tank replaced by peugeot, got 50% off parts labour, paid £713, I wasn't happy so I complained to the peugeot ceo, UK director, and customer services and I am now waiting on a full refund.
Just been informed Peugeot are footing the bill for tank £1140
So was yours in the 5 years guarantee period? Did you email the CEO?
I was 1 month out but a good customer for many years

I hope I get the same outcome. Turns out mine is the adblue tank which needs replacing. The error occurred on the 8th July which was the day my 5year warranty ran out!! So Desira are fighting our corner and hopefully we get good news.
Hope all goes well with you

Thanks for the replies to my post, apologies it has taken a while to reply! After a few more decent drives, including 200 miles of motorway driving, it was pretty clear that the tank was the issue.

Found this tank on ebay, which I've now fitted. It's the same model number as the tank I took off. Good news is no more fault codes, and the nox readings are back to normal. Unfortunately I still have the emissions fault and mileage count down warning on the dash. So presumably i have fixed the problem but the tank needs mapping? There is a manufacture date of 2020 on the tank so is it possible there is some of the newer electronics in that would require the mapping even though it is the older model tank?

I have an appointment at a dealer next week which was for diagnostic, but hopefully can just be for them to map the new tank.

One observation which might be useful is that I put 10l of adblue in when the issue first arose and only about 8 1/2 came back out two weeks later. I'm guessing the tank was completely empty and that is what caused the original issue, despite the dash still giving me 1200 miles.

Good for you fitting new tank as you say think you will have to visit Peugeot dealer to program ECU out of interest what year is your car as you might be under warranty 5 years AdBlue cap was the problem not venting tank.

It is a 2015 model at about 48,000 miles. I didn't buy from Peugeot and have intermittently had it serviced by a local garage and myself (major and minor respectively), so not expecting much interest from them. Plus they quoted me £175 for diagnostics, then 2 - 4 weeks lead to get parts and fit etc. By the time I had worked out hiring a car to cover me for the intervening period I came to the conclusion that it would be cheaper to do myself, even if they paid for the tank. My biggest worry was they would identify the tank as the issue and then I would be in the £1100+ world of pain!

Should have also mentioned in my previous post, it literally took 20 minutes to drain and take the old tank out and 20 minutes to re-fit. I'm very much an amateur mechanic - anyone with basic skills, a T25 bit and a decent socket set could do it. As a previous post mentioned the most difficult part is releasing the wiring connectors!

I'm in the process of having my tank changed Peugeot are footing the bill.Years ago i would have been like you and removed tank and see if i could change the pump thats inside but being an old git now if it involves laying under cars its a nono i'm 75 years old changing air filters and cabin filters is my mark now or fitting like ProBitz chip the joys of getting old i do miss tinkering with cars the old ones where you don't have to plug anything in.Hope you sort the problem out sure you will.

Hi Lewis,
From my understanding, if the tank is changed from 2015 to 2020, then yes it would need the engine ecu updated. The tank won't be recognised by the car's ecu. I would expect it to be displaying the fault U029E "Fault in communication with the denox system - no communication". This would be shown as an engine management fault and lead to the countdown.
- Unless the tank, pump assembly or pcb have previously been changed.
If you've opened up your old tank which version of pcb do you have (red circles). The missing common mode choke replaced by two zero ohm links (on the left pcb) is the newer version:
94590

If not what are the dates shown on your old tank? Note there are two locations for this. The most important is on the lid of the pump assembly; location shown in blue:
94591

If you already had a new style pcb, then that would explain the lack of fault codes.

It would be very useful to understand what is happening, so some questions if you don't mind:
Which version of tank/pcb was previously fitted?
What diagnostic tool are you using and how do you know that the nox readings are back to normal?
Since fitting the new tank how many miles have been driven?

Hi,

I'm sorry I haven't had the tank apart yet, but I recall the date from the wiring loom being 2015, so safe to assume that the tank is 2015 also. I'll try and get a picture of the pump up later in the week.

In answer to your questions in order:

Previously fitted tank - old / 2015 tank. Replaced with a tank with the same part no. 9807475780 but was manufactured in 2020.

I'm just using a cheap ADBII sensor and a free app.

Note, I didn't see the communications error fault with the new tank - no active faults whatsoever.

When I first received the emissions control fault error and had some error codes relating to the NOX sensor, I used the ADBII to check the NOX emissions while driving along - this gave me a pretty good idea that it wasn't the NOX sensor itself at fault. I saved the data and it was running at 700-1100ppm depending upon type of driving. I repeated the test with the new tank on and it is down at 80 - 200ppm, which is what I would expect for a working system. This together with hearing the tank pump whirring for a few seconds after turning the engine off gave me confidence that the tank swap had solved the problem.

I took the car for a test run immediately after fitting of about 25 miles, and have since covered another 15 or so.

I booked the car into an independent peugeot specialist this morning and they have re-mapped the tank and say the fault and countdown have been cleared. They have charged me £58 inc VAT.

So over, all very happy with the result, and I have met my wife's deadline of needing the car for several hundred miles of driving over the next week from tomorrow! This means I avoided having to hire a car for £350 or so as well.

I will take my time over the old tank and see if I can replace the pump and either keep as a spare or sell on. If anyone on here is interested in the old tank, let me know and I'm sure we can sort something out for postage and nominal amount etc.

Thanks for the update.

Sounds like you had a 2015 tank, so I'm surprised that you didn't get a fault message, and sounds as if you had done enough miles to get the urea warning to clear without the remap. Another bit of useful information.

Its great that you got it working and that an independent specialist can do the re-map and for £58.

So turns out Peugeot are going to foot the bill for it!! Just had the phone call confirming as a gesture of good will they'll pay for the fix. I'm massively relieved. Thank you so much for your help on this one. The only slight frustration is I now need to wait until the 17th August before they have a free slot... but considering they're going to be paying that doesn't bother me much at all.

Hello,

First of all I'd like to thank everyone that contributed to this topic. It was a nice and long read.
I have a Peugeot 508 RXH from 2014 and got the P20E8 error.
I tried to drill a small hole in the cap(altough I think I have the new cap) and also to hit the tank with a rubber hammer but no luck.
I also erased the error after but it came back after a few kms, so no luck with that either.

So I guess my options right now are to replace the tank with a new/used one, but neither of that really excited me since the problem could reapear at any time and I don't have warranty for the car so I might as well burn that money.
But I have a question. After I erased the error it came back but the km counter got back from 700km to 1100km (that was the original counter when the error first appeared). Question is: could I just buy a tester and erase the error every time the km counter comes close to 0? Someone told me that even though the car shows 1100km again, it's actually still at 700km so basically when it will show 400km it won't let me start the engine.

Did any of you try this method and can confirm/deny that it actually works? I will eventually replace the tank but since it's summer I'd like to go to vacantion peacefully and not burning vacantion money on this error.
Also, if it does work, can you please recommend me the cable that will connect the computer to the car? I have Diagbox 9.68 installed on my old PC but I don't know what cable I need.

Peugeot ain't that bad after all had a new tank fitted in mine last week all good now best of all NO £1000 bill glad it went well for you.

Hi Liviu,
When you tried the rubber hammer, was there power on the circuit (e.g. ignition on)? If not it might be worth a try (it worked for me).
I have used a plug-in Pumpkin OBD2 ELM327 Bluetooth Car Scanner-Torque Diagnostic Auto Scan Tool (£7.99) and a phone to reset the countdown on mine. As this was bought in 2016, it appears to be no longer available, but a similar device should work.

I don't get the impression that the 1100km countdown was not fully reset and I haven't heard of it before, but I've not used the full distance myself.

Thank you, Tom!
To be honest I only tried with inginiton off so far, I'll try again tomorrow with ignition on.
Thanks you for the details, I was actually quite baffled because the only things I could find were some 100$+ Lexia tools and I tought that those were the only ones that could help.
I'll come back with updates. Cheers!

Don't raise your hope regarding obdii device to reset the urea error. In most cases , the error will return after few miles .done that , been there.
Chinese sites offer them for just few bucks.

I'm aware of that. I don't mind the error, I just want the km counter to reset so I can use my car.

From my experience:
Reset the faults using the ODB2 bluetooth device (ignition on, engine not running). Engine management (EM) light OFF straight away. UREA light OFF after a short time (guess a minute or so).
After the engine reaches 80C (about 5miles for me) the EM light ON, followed shortly by UREA. Drive 50km (31miles) and the countdown warning begins (gives 700miles (about 1100km) before restart prevented in UK).

If the fault is reset during the journey, (ign. off, engine not running), EM off straight away, UREA off after short time. After about 2 miles (note engine is still warm) then EM ON followed by UREA. After another 50km countdown starts from 700miles. Note I found the countdown warning very annoying (flashes warning on touchscreen every 20seconds or so), so I would mainly reset mine before reaching the 50km.

Diagbox is very useful if you are looking at repairing the tank itself to try and understand what has failed. Also if you have no communication with the urea tank (fault U029E) it can be used to reset the countdown back to 700miles. Although as you only have P20E8, that shouldn't be an issue. I can't advise on the Diagbox Lexia3 cable.
