urea warning light

[Jamiebamf]

Hi,

Sorry if this has been asked before, I did search but didn’t find much.

My 2017 citron berlingo had the urea warning light come on today and the screen said I have 1500 to before before the engine won’t start.

Is this just any old AdBlue? If not, can anyone can recommend a product I need and where it goes?

Cheers

Hi, If you have a separate blue filler cap beside the fuel cap then it's regular adblue. If not, it's a pouch system underneath the van - inside a black box shaped cover in front of the driver's side rear wheel which houses the pump and a pouch of fluid. It needs to be swapped for one with the same neck colour (red, green or blue etc) and is about £100 for a pouch of fluid off eBay. The neck colour denotes the type of fluid so has to be the same as the one fitted already. The others are not compatible. Different colours are different chemicals that they used over the years.

If it's the pouch, then the ECU needs told it's been changed as it can't measure it. It guesses how much is left by the miles you've done. Anywhere near £100k now? That's how long the pouch lasts.

This reset has to be done with Citroen software called DiagBox. Some indy garages have it. Citroen dealers definitely do. Otherwise it will still complain and continue to count down to no-start as it can't tell you've fitted a new pouch.

My 2016 Berlingo did the same thing today. Fortunately its regular AdBlue and we already had some left from the 2 VW's we have (They seem to drink it like its going out of fashion) so just chucked what was left in and the light cleared.

My only question is, How big is the tank? The Google search says Citroen uses 17L tanks which seems rather large?
I've only put 5L in so will get some more tomorrow.

If you have the regular adblue tanks cap beside the diesel one then it self resets when you top it up. The older pouch system doesn't of course.

I mentioned the reset as the OP asked where the fluid goes, so I assumed if he had the regular adblue blue filler cap right next to the diesel cap, he'd have noticed that before now. But, it should be that system on a 17 plate as yours is.

I did notice my previous Audi guzzled it quite a bit.

17 liters, that's right.
