:) Hi, i had the same problem with my c4 grand picasso 2015.
Mine it show engine fault have the vehicle repaired and exactly after filling my car, and citroen app running.
Citroen wanted to charge hefty amount to repair.
And as i had a bad experience with a citroen dealer before, so i went on ebay and bought a complete diagbox( after market of course).
And plug it to my car and ran a full diagnostic then i went in the ecu and pressed on show faults, the fault was addblue topup, i filled the addblue tank and then adjust it in the system and it has cleared the fault
If you still need the instruction i can help you with all the steps
By the way: delete citroen app or put it 😴

This is a little more than adblue topping up!

Sadly I know it has plenty of Adblue in but I appreciate the input, when the issue first happened I was hopeful of a quick fix but 9L of Adblue was all it would take.

Having the updated venting Adblue cap fitted might have been a curse here but presumably the system was failing already from it not being done years ago.

Citroën really need to get on top of this IMO.

They have replaced the tanks on later models - they swapped out a lot more metal parts with plastic ones as the metal components were rusting up (no surprises there), the venting system was improved as this was causing pumps to fail. On older systems a vented cap was utilised to replace the original. But I'll be getting extended warranty when my manufacturer warranty expires in a year or so, just in case.

That's the worst thing about all this for me, they know there are issues, they know how much it's costing people, they need to just recall the cars, take the hit and build customer confidence because it's sure as heck tarnished my opinion of the brand, a shame as they still offer some really interesting cars that stand out from a lot of the much more expensive white goods stuff out there.

Extended warranties will definitely be factored in on future car purchases!

I can personally recommend the Citroen Extended Warranty - never had a claim refused for my C5 X7. I think over the 3-4 consecutive years I was invited to extend it, I had over £6.5k of work done for an annual cost of about £230, so was well pleased. Some examples of what I had done: New driver Wiper motor module, complete electric window motor and regulator, crankshaft oil seal and replacement of already new clutch that was contaminated, suspension pipe, new A/C condenser, new A/C compressor, 4 new uprated TPMS sensors, new steering rack etc.

I don't know if I'm more impressed by what they've covered or just terrified about all the bits that have needed doing :shock:

Before I finally decided to sell her (after a lot of deliberating as I didn't really want to let her go) at 72k miles, I had not renewed the warranty for a few years again as I was not doing the mileage - however sod's law - it needed another steering rack and a front hydraulic suspension strut and the passenger window regulator decided to go too, so that was another £3k of work at dealer prices. So I had my local garage replace the regulator only this time, they also fitted the new rack, had the timing belt service water pump and pulleys done and Citroen did my strut, but I supplied the strut myself.

So if you have a complex car or any Blue HDi with an SCR system I would wholeheartedly recommend a manufacturer extended warranty.
