Both yours and the one a couple of posts above. I expect mine would be different as it's a 508 2.0 bluehdi 150

I read your technical post. I wish you were right about the sensor . It's just I've seen this problem too many times.
First: the injector costs around 120€ .
It rarely fails and it is easy to hear it is working without disassemble.
The injector can fail at very high milage. 200000+.
The urea line is rubber tube and unless you had an accident below the car: it should not leak. In all cases I saw P20E8 within blueHDI 2.0: the urea pump simply died. Slow and painful death...
If you can find a used pump you might be able to replace only the pump module yourself, but it requires some knowledge. Not everyone is ready for DIY solution that might not last long.

Yes dealer knows of the requirement to change the blue filler cap of the Adblue tank.
Also Clutch pedal needs looking at and also Cam Shaft Pulley.
So all three of these TSB booked in FOC, also as I'm under warranty they will collect and return car from me FOC, they are hoping to complete in same day.
Seems the Cam pulley a large job. Have the forum covered these other things as I can't spot them, links would be good if in the forum.
Thanks.

Save2, thanks for the reply. Is the pump accessible in the tank? If it is I might take a look. I have been a maintenance engineer all my life so a pump is nothing to scare me. And if I can save myself a load of cash to get it running long enough to get rid of the car...

Well we appear to have been "Lucky" or "Unlucky" dependant on how you look at it - My wife and I purchased a 2015 3008 BlueHDi Allure and collected on Saturday - the collection itself was a nightmare, but that's another story - 1 mile into our 65 mile journey home the EML & UREA lights came on, shortly after the UREA light started flashing.

As the vehicle is in its last week of warranty, we booked it into our local Peugeot dealership on Monday and they accepted it the same day - just spoken to them now, 3 are three recalls - Adblue cap, Cambelt & Something else about corrosion? anyway, they've replaced the cap and roadtested - surprise surprise light came back on - apparently they are now having to replace the tank?

Me too. I'm thinking of getting a pump from a scrappy. Don't know if they are interchangeable model to model but they do all look similar just the tanks seem different shapes. Anyone any ideas?

Wow, you were 'lucky' I believe!

Let us know what the dealer does please....I am still debating (with myself) what to do.

I certainly will, they said something about having to get permission from Peugeot - I presume cos of the cost of the parts - but said it should be up and running for me tomorrow.

I'm going to ask for a copy of the work that's been done and I'll let you all know,

I have just written to Peugeot (copied below) via their customer service web page to see if I get anywhere with this problem. If I don't I intend to pursue the matter further.

I believe there is a known problem with the pump failing in the Adblue/Urea reservoir on various Peugeot models. This is known to be caused by inadequate breathing/ventilation to the reservoir/tank making the pump work hard to try to pump the Adblue when there is no air being allowed in causing a vacuum. Hence the pump fails prematurely. ( Mine has failed at just over 11,000 miles.)
This problem has been acknowledged by PSA as they have recalled many cars to have a new Adblue filler cap fitted which has a breather built in. In many cases however this recall is too late as the pumps are already damaged and the only solution is the fitment of a complete new reservoir at a staggering cost in excess of £1000. What are PSA doing about this? It is obviously a design error and as such should be repaired free of charge as the item was clearly "UNFIT FOR PURPOSE". I await your comments.

Don't bother: I wrote to PSA UK customer support and even gave them a link to this forum.
Their answer was a complete denial of the facts:
There is no "known issue". They won't comment on some forum post and they recommend I visit a Peugeot dealer for a checkup.
Personally I think they try to avoid replacing all tanks due to its cost ( a cap on the other hand, is cheaper). Beside this is not a safety issue.
IMHO: such behaviour doesn't help the brand reputation.

I'm sad to say that I've p/exd my 2.0 Bluehdi for a 1.2 Puretech version. Seemed like the best solution would be to land PSA with the problem rather than shelling out myself.

I was concerned about the mpg difference....but I needn't have worried. The 2.0 diesel auto did about 52mpg over mixed driving and the 1.2 petrol auto does 50mpg. Amazing engine all round.

Anyone managed a fix yet ?

Well, the discs and pads needed replacing too, plus the a/c condenser was also giving trouble. It had 45k on the clock and 1 swapped for a 22k petrol with new tyres and brakes plus a 2 year Peugeot warranty. £3k in all

Hi Paul,

Allure with glass roof v. old Feline. So not quite, but I'm broadly happy with the deal. My overarching desire to 'fix' things was outweighed by the security of the warranty and the lower mileage. Must be getting old !

Mike
