AdBlue Remap Question

[sswindon]

I have a 2016 Citroen Berlingo HDi with AdBlue. The urea and yellow triangle warning lights have recently lit up and the screen is showing the error “Emissions fault”.  No mileage countdown yet. I’ve filled the tank with 10 litres of urea but warning lights still on and emissions fault error still showing. Rather than spend money on getting the issue investigated and resolved which could cost £1,500+ I have been looking at getting a remap. Can people please share their experience of mapping the AdBlue out? Is it illegal, do you need to inform insurance company and does it impact MOT?  Thanks.

What you really need to do before anything else is to have some proper diagnostics carried out via the OBD port to see what actual fault codes you have and then work on from that information. I have a pre-Adblue, and pre DPF B9 Berlingo but I think your 2016 model may also have the Eolys fluid system as well as AdBlue and that has been known to throw up problems. The reason for both, is the change from Euro 5 to Euro 6 which had stricter levels of NOx emissions. Adblue brings the NOx levels down to the required limit while Eolys helps to burn off soot in the DPF. It also reduces NOx but not by enough to be approved for Euro 6 so I think they retro fitted vehicles already in production or stock with Adblue tanks, so they could still be sold in the EU. They presumably already had the Eolys system fitted from before.

Note that generic OBD readers are not any good on PSA group vehicles. I have used the REDOBD on my Berlingo B9 and that seemed to work fine for me [others have had mixed results] but for an outlay of less than £30 it was cheaper than taking it to a Citroen dealer for diagnostics. In my case it correctly diagnosed an ABS fault on my B9.

If you are interested in getting a REDOBD scanner then there is a 'sticky' thread in the forum with a discount code. It takes a good few days to arrive as it is posted from [and made in] Germany.

When mine needed the eolys fluid refilled, it didn't show the urea light, just the yellow triangle and "engine fault have the vehicle repaired" on the central screen. As multispacer said, I would suggest getting a prober diagnostic to see if that throws up the origin of the fault.

Thanks for the info. I am keen to get an OBD device but not sure which one to go for so this is very helpful. I can’t find the sticky thread you mention and a search on REDOBD doesn’t bring up anything useful. Are you able to point me in the right direction please? Thanks

For some reason the shop link in that post doesn't work but the site is still there under this: https://www.obd.red

but I don't think the shop is working/selling the unit. Maybe contact them directly via the email address?

Thanks. That’s a shame that it isn’t available. I’ll contact them. I may have a go with a couple of different units from Amazon as I can always return them. I’m under a bit of time pressure as I’m supposed to be driving to France on 8th June.

I wouldn't bother with any of the other generic OBD readers, as 99% of them will not read anything useful from any PSA group vehicles, that is why there was a lot of excitement on this forum about the RED OBD.

No idea about mapping AdBlue out I'm afraid, my Berlingo being a 2009 version has neither AdBlue, Eolys or even a DPF fitted, so I've never really got involved anything to do with AdBlue and I cannot ever remember seeing anything to do with AdBlue remapping on the forum but if it has been mentioned, hopefully another more knowledgeable member will give you an update.

Honestly, I'd not bother with the RedOBD.

Little more complex, but I'd go straight to the Diagbox software as it (mostly) mirrors what a dealer would use, and it actually talks properly to the systems, so you actually get all the information correctly. But it's not really a beginners' tool to set up and get working, you need some IT ability.

If you don't have that - spend the £20-£50 and get someone with the correct tool to read the fault codes.

If it's a BlueHDI, failure of the urea pump is quite common across Citroens, caused by a poor design of filler cap which didn't allow the tank to vent properly. https://www.berlingoforum.com/thread-23481.html

Thanks. Diagbox is Windows only as far as I can see and I only have a Mac so that’s a no go for me. I’ve got a mobile chap popping round to check the codes. My filler cap is the newer vented design (white cap in centre).

We are having the same problem on holiday in Europe on '66 plate hdi 1.6. Mechanic saying to get back to UK he'll disable the adblue as needs new pump and tank. None available. We have to contact Citroën on return to open a case number and hope they replace free of charge. As it's not a safety issue they're not recalling!
