I would guess that the S/H one is the original AdBlue tank and the new one is the supersession tank. The S/H one has two part numbers, the second one of which is the same as the new one.

What the piece that sticks out at 45° is I don't know. But it may not be important.

Just wanted to say thanks for the replies.

I have ordered a tank for £350 second hand/new

My local garage said looks all good and will charge 2 hours labour about £150.

Will update once delivered and fitted.

Did anyone actually test the new cap and see if it lets the air in?

I'm taking my car this Saturday for a cap replacement. I bought the second hand 2.0HDI 110KW. It has over 115.000 kilometres on the clock, and the old cap, so how it's possible that pump is still working if the vacuum is the problem?

Also, why wouldn't I just remove the cap and keep it like that so there isn't a vacuum?

 

[Brilec]

Apart from the slight risk of spillage, why not just drill a small hole in the cap? Leave the cap off, and you will get the stuff all over the well in the back.

I guess I could drill I hole, but it's almost Saturday, I guess I'll just wait and see how new cap behaves.

Did you check what urea tank version it has?
Maybe it is not about the cap at all...
You are right. I tested the new cap . It is air tight which makes me wonder how it really works... I believe drilling a small hole in the cap will release enough air yet still prevent urea splashes getting out.

How can I check urea tank version? Btw, dealer didn't have the correct cap, they had to order it and I am waiting for it now.

Kneel behind right rear tyre and see if the plastic tank has its part number on its side.

Update on my replacement tank.

Picked the car up from the garage.

£580 includes:
Fitting my replacement tank
Clearing the error code
New front brake pads
Replace gator cover
Service
MOT

Remember the tank cost me £350

Done 30 miles today and all good.

 

[Brilec]

Well considering I paid £260 just for a service, I don't think you have done too badly overall.

Here is the new cap.

I tested it by trying to suck the air from the bottom of the cap, and it indeed lets the air in, so I recommend to everyone to go to the dealer and replace it. Replacement is free.

 

[Paul-R]

When you tried sucking through the cap (sounds like a euphemism) did you find difficult or easy? When I tried it let air through but only very, very slowly. Now that's all it needs but I wondered if that's right.

 

[mara-]

I would say something in the middle between difficult and easy. I just hope the pump will last a long time. I bought used car, 115.000 kilometers on the clock, no indication that pump was ever changed and it used the old cap all the this time.

I have just read this mammoth and interesting thread.

Mine is a 2016 reg Partner Tepee 100 though I'm sure it was manufactured late summer 2015.

After 16000 miles no problems as yet but I am still on the old type adblue filler cap so it seems to be a good idea to drill a little hole in it and maybe replace it a later date. Is that the best way?

 

[Paul-R]

Well if it's 2016 it's still under guarantee so I would go to your dealer and ask them to change it. It's a ten minute job on the 308. I'm not sure where yours is - by the fuel filler perhaps? Possibly not a problem with that type?

 

[Trickie]

I just drilled a 1 mm hole bang in the middle of the cap. So big enough to allow air in but small enough to keep dirt out.

As for the warranty that is a long story.

3 year warranty expired end of March.
I tried to get it serviced by the Peugeot dealer at 2 years but found Peugeot UK would not honour the warranty because it missed the 1st year service. That is because it was off the road on a Sorn statement for nearly 12 months. It had only done 3000 miles. So I stuck 2 fingers up and went on my own for the servicing.

That's how Peugeot treat their customers.

Rant over:lol:

 

[zendra_cro]

I have the same problem, car is 4 years old, under 150 000km, need new adblue tank, and my dealer does not want to change it, so now we are having a war.
Anyway, has anyone fizicaly taken the tank down, open it up and try to fix pump? Is there some DIY repairing the pump so if would work again? Or there is apsolutely no other way than buying the whole thing new...

 

[Paul-R]

You should read this entire thread through from the beginning. There is a lot of interesting and useful information that may help you repair the pump. No-one has done just the pump yet to my knowledge but that is surely the next step.

At the very least the information should help you identify a good second hand tank perhaps.

 

[Trickie]

Earlier in this thread Jonsy replaced just the pump mounted inside the tank and it worked. So it appears the pump itself fails and the rest of the electronics remain good.

My question is can a pump be salvaged from any Peugeot or Citroen range adblue model? Is the pump the same in all of the tanks?

I would expect them to all be the same.

 

[Paul-R]

Well, we know that if you order a brand new complete tank that a supersession has occurred and that something in there has changed because a Diagbox has to be used (with a link back to the PSA servers probably) to pair the new tank to the car.

It would be very useful if the pump hasn't changed as this would do away with the pairing problem and I think that this is hinted at in one of the posts.

Now, are all pumps throughout the PSA range the same? That would be lovely, wouldn't it?
