Well, I am not from UK. Maybe there are some consumer rights you have even if you service outside of Peugeot, so maybe you should check it out. It's really dirty trick that Peugeot does, since regular maintenance has nothing to do with ad-blue system.

Formula 1 & In n out are both fast fit centre's.

I wouldn't expect any kind of repair contribution from Peugeot once they find out the vehicle has been serviced by either of those places.

Update about my Peugeot 308 2016 (sept), taken to Peugeot today, getting 50% off parts and labour, costing £560 plus £150 diagnostics, still alot but better than £1200-£1300+
Are they changing tank i had much the same probs with mine had a Nox Sensor fitted which got rid of warning also TSB on software on g/box update car seemed to perform better then had car MOT Engine oil filter and fuel filter changed then the UREA light came on called RAC out who done a diagnostic check he said it had a few faults which he cleared but he couldn't clear the EURA LIGHT said it was the tank after taking AdBlue cap off and taking the tiny filter off and driving car around all the warning lights went off cap replaced so far no warning lights etc

I am looking for some advice on how to proceed after my local Peugeot dealer investigated the "UREA : Emission fault warning message" and revealed fault code P20E8 00.

They topped up the urea tank (although the dash message still showed more than 1500 miles remaining) and cleared the fault. They said that if the fault message returns I will need a complete new urea tank costing over £1,000 !!

Guess what, 5 miles later the message returned. I went back to the dealer, but no joy. They believe the fault means the pressure of the urea fluid is too low, which means a new complete tank. The car is a Sept 2014 2.0 Bluehdi 150, and so is only a few months out of warranty. It has had all the recalls undertaken including the urea wiring loom.

So, what could be the causes of low pressure. A hole in the tank ? A faulty pump ? A blocked atomiser nozzle ? Are any of these fixable without replacing the entire unit ?

Would any of you know of a specialist who could look at this....other than one of the main dealers ?

Any help and advice would be very welcome. Thanks.
I've got a 16 plate citreon c3 Picasso 1.6 hdi with the same issue and fault code, I bought 3 years platinum warranty and took my car to the Garage whi deal with my warranty, and after looking into the issue I've been told that Citreon are aware of the issue with the adblue tank and are replacing then free of charge, the warranty company won't have to pay but Citreon are not recalling them their only doing them when the become faulty, so you should be able to get this done free of charge.

Good afternoon,
In Spain we are having the same problems, in my case my car is 5,1 years old and finally I will change my Ad Blue tank for 340€ all. This is a fabrication defect and Peugeot had to pay for it, not us. Here it's our web page: INICIO

Hi, Is the AdBlue cap issue an issue with 308 SW? I've stumbled over this thread and I checked the cap on my 308 SW and noticed it's not the blue one with a white middle. Would it be wise for me to buy the new cap before anything happens to my pump and tank? Or does is it not the same issue with the 308 SW? It's a 16 reg diesel (obviously)!

It is an issue. Just ask for recalls to be done on your car and you will get cap for free at the dealer.

Hi, I've read through this thread and it's been massively helpful. Thank you so much for all the input you guys have contributed. I do have a couple of questions because a few things have slightly confused me.

I have a 308 SW, 1.6 diesel 16 reg. This same error message P20E8 came up and I've added 10l of adblue and driving it without the cap on etc. and that hasn't sorted it out. So I think I'm at a place where I think I'm going to just bite the bullet and get the tank replaced.

1) The code on my part is 12674101. I got a bit confused about if I need to buy the exact replacement, or if Peugeot brought out a new better version tank I need to get. Should I just get like for like or a different tank?

2) The cheapest new part I can find it for about £750. The cheapest used part I can find is about £350. That's is quite a difference for me (fairly low wage, and Covid has hit my finances). If you were replacing, would you go used, or would you go new?

3) Liked to question 2... Is this particular issue an issue with the cap or the tank? I.e. would getting a used tank but making sure I have the correct cap ensure this problem doesn't happen again?

4) I'm not great at cars, but I have an American friend who is pretty handy at this sort of thing. Would it be worth us having a go at this, or should I just take it to the local garage and get them to do it?

I'm really sorry for all the questions, I'm just trying to weigh up the best course of action for myself. Thank you once again for all your help.

Hi Donald, That is great news. Unfortunately for me, I have the old cap and when I tried driving around with the cap off the same error code came up! So I think fixing the cap on mine is a bit late frustratingly!

Hi,
I don't believe that 12674101 is the correct part no for a 308sw. From a quick search it appears to be the Adblue tank for Citroen C4. So it is has some mechanical differences (mainly pipe connections?) to the 308's. So far most 308sw seem to need 9818559380. I have read that the ending 380 is the slightly newer version, earlier versions 280. BUT check for your car. Note that if your buying it new, the supplier will check against the VIN.

Please read my post #510 on what is inside the tank and re-programming on newer tanks.

For fault finding you really need access to the Peugeot diagnostic tools (called Diagbox). From what I have read and seen, most tanks don't seem to die due to the vacuum from the adblue tank cap. They either leak internally, have a bad electrical connection, or one of the internal electrical comments die. If it was an intermittent fault I would suggest a bad electrical connection on or inside the tank.

Removal and access into the tank is fairly easy, so earlier posts in this forum.

Hi Tom, thank you so much for this. That's really helpful. I got that number from my car. I crawled underneath and took a picture of the code. It said 12674101. So is it possible that the previous owner actually installed a Citroen C4 tank rather than the correct Peugeot 308SW tank? I did buy it second hand. Cheeky them.

I assume the solution for any of those issues you mention (leak, bad electrical connection, or dead comment) is getting a new tank and installing it?

Hi Tom, also, thank you so much for directing me to post 510. That was really helpful. So if I get the new tank something will need reprogramming. Which I'll have to take to a Peugeot garage to sort out? Any idea on how much they charge?

Sorry, I wasn't fully "with it" when I responded to your first post. The part numbers 12674101 is actually the part number for the plastic moulding that is the bottom of the tank and not the complete tank assembly. This moulding is used across a range of Peugeot & Citroens. So you probably do have a 308 tank. I have not found anywhere, where the complete tank assembly part number is marked.

{Just a quick note on the C4 tank. A quick look at a couple of tanks on identified as "Citroen Grand C4 Picasso" on Ebay suggests that it would also mechanically fit a 308. The different pipe arrangement I mentioned earlier are just the breather / over-pressure arrangement on a 2014 tank. Later C4 tanks on Ebay show the same breather /overpressure arrangement as the 308s}

On low pressure, there may also be a chance that there is a leak on the pipe to the adblue injector or a fault on the injector, BUT I think that these show as different fault codes. A leaky pipe would also show as a white streak under the car when dried.
So changing or repairing the tank is probably the long term solution. Repairing is not straight forward, it depends on what is wrong. For the short term, the fault can be reset by one of the cheap OBD2 tools. It will then reappear after about 5 miles.

My local dealer charges wereo_O:
If I wanted Diagnostics done first £117, i.e. an hour at the standard rate.
If I only wanted the coding of a tank that I had fitted £117 (assuming that it was (a) the correct tank (b) there was not else wrong with the system)
Fitting and coding of a customer supplied tank £175 (assumptions above)
If they did the complete job e.g. diagnostics, fitting, supply and coding of the new tank £1200!!

Ouch, that is very expensive. This is really going to cost me. I suspect it'll have no impact, but I might contact Peugeot customer services and ask if there is anything they can do. I think they'll just tell me to "go fish" but it's worth a chance. I had a look on their website, and it seems getting a contact email address is quite hard. Any ideas how I get an email address or something like that?

Sorry, I haven't been in contacted with them, but worth a try. I've gone down the fix it yourself route, with partial success so far.

I have to say, I feel like my best bet is to buy a second hand part with the code you mentioned (i.e. the 9818559380 code), then get my local mechanic to install and code. Hopefully, that will come closer to £500 rather than £1,200. Does that sound like a decent enough plan? I don't want to do anything too stupid considering how novice I am at this!
