'16 Cactus - 1.6 HDi - P20EE / Urea Light Flashing (and more...a bit long, sorry)

Idle thought but as it was the first time you have added diesel since the AdBlue tank was replaced could it be a case of the system self adjusting itself if a fault code was still stored even after being cleared until fuel added?
Similar to Abs fault that would stay lit until being driven over a certain speed even once cleared and parts replaced.

Could well be, I've started the car about 4 times and driven 100 miles or so and it hasn't come on again so might just have been an odd blip.

I feel like I shoukd maybe log it with them just so it's on record now rather than leaving it but then just see what happens.

Yes, I would certainly do that, so they have record of it and do soon after replacement too,

Still going

So the "Engine fault" when putting diesel in went away as mentioned a couple of weeks ago, it's been really hectic and I forgot to call the dealer to discuss it. Then last night I popped £20 in again and the same happened.

Switched car off and on, it popped up again. Repeated, no warning and nothing since - pretty much the same as happened last time.

I called the dealer this morning, explained the symptoms, told them it didn't do this prior to the Adblue tank being replaced etc and they said they would need the car in, would run diagnostics and if it was related to the work carried out it would be covered under warranty but if not it's £144 plus whatever it costs to fix. I don't want to give them £144 and I'm pretty sure, based on how they've been to date, that's the way it'll go.

In my eyes it's the EOLYS system throwing this up giving the timing of it when I've refuelled but I may be way out, I can just see them saying it's not Adblue tank related though.

So what do you do? Like I said it didn't do this before they replaced the tank, it does now. Unlucky coincidence? Something they might have caused?

Live with it and get on with my life but fill up with diesel in advance if I ever trade it in?

Buy Diagbox and a Lexia 3 (I think that's right?) and do the diagnostics myself instead of paying them for the same?

You'd also need a laptop and oodles of patience on top of the kit costs.

You could well be correct in that it may be a separate issue to do with the DPF system. The DPF system is separate and not related to the SCR system. If you are getting the warning up after adding fuel, the fault could well be to do with the additive pump not being able to dose the fuel tank after fuel has been added. Calculations are made once it detects fuel has been added and measures fuel quantity when the engine has stopped and again after it is started. If it detects fuel has been added, it calculates the volume and doses the tank accordingly.

If the additive pump is faulty or the tank is empty it will trigger a fault - for which you will need a proper code reader to obtain the codes. Normally if the DPF additive tank is getting low, there will be a warning telling you that the additive level is low and needs topping up. The issue is that the DPF additive tank does not physically measure the additive remaining by any mechanical or electrical float. It is purely calculated from the amount added at factory and the amount injected over the miles.

So if the additive pump has run dry or there is a fault / wrong additive being used, the pump may not be operating properly which may be causing a fault. Either way a diagnostic is unavoidable to be honest.
