My turn: car is Cactus 1.6 blue Feel 2015 (65 plate)

Bought the car in June last year (2019) from Evans Halshaw. This Saturday (29th February) the engine management light came on with "engine fault: have the vehicle repaired" displayed, this was quickly followed by the UREA light coming on and the message "emissions fault", also the SERVICE light (although service not due. There is NO countdown of miles displayed where car will fail to start.
I have an OBDII code reader but when connected it discovered 6 faults (4 faults/2 pending) but was unable to give fault codes?
This morning I topped up with AdBlue - tank took the full 5ltr can - but the lights are still on but still NO mile countdown indicating failure to start.
Since I bought this car in June and 4500 miles later that is 15 litres of AdBlue that it has taken. Is this normal?

After reading a lot of these posts I am starting to get very nervous about a huge repair bill if it has to have an AdBlue tank replaced.
I agree with a lot of people, if Citroen are replacing a lot of these AdBlue tanks on relatively 'new' cars then surely a recall should have been carried out?

I'm going to see how it goes for the rest of this week, as some people are saying the lights went out after a couple of days? Before I decide my next move.

An after thought, I recall back in November I was driving up the M1 at night when suddenly the SERVICE light came on, followed by the UREA light but NO engine management light, but after a few miles, they went off and this is the first I've seen them light up since that night.

Car has done just 39,000 miles from new.

Thoughts please? Thanks.

I have a Citroen Cactus C4 BlueHdi 1.6L diesel car 65 reg. It has done ~40k miles and suddenly on a drive home on the motorway 3 days ago, the UREA + SERVICE + ENGINE MANAGEMENT lights came on together with an audible beep with on-screen message saying "Engine fault: Get engine repaired". The lights weren't flashing and had orange colour. When I read up on the car manual I noticed that this is an error with the SCR emission control system. Reading this forum and other google pages, I decided to top up my car with 13L of AdBlu. It was surprising that the AdBlu tank was empty but I did not get any low AdBlu warning. In the past when the tank was low, I got the UREA (AdBlu) warning but this time I didn't.

After topping up with sufficient AdBlu, I also checked to see if my tank was of the new model based on user information I saw on this forum. My AdBlu tank P/N is: 9812914780. I took my car for a 2 mile ride however all the three warning messages were still on. I worried if this might be a bigger issue than I thought (maybe a broken pump, bad tank etc..) then I took my car for a 3 mile ride on the motorway speeding up and down to get the engine pumping. I was delighted to see that after 6 miles of driving, the UREA + SERVICE lights went off. The Engine Management Light still stayed on solid.

After reading this forum, I noticed that for some people the light disappeared by itself after ~36 hours. I decided to give this a try and after 2 days (this happened over a weekend) when I started up my car on Monday, viola! the EML light too disappeared and I was left feeling relieved! :) .

When the faults first appeared, that day I called up my local Citroen dealer and the lady told me that I should bring the car in for a £125 diagnostic of the faults before any repair work commenced... She said that from her experience when all three of those lights come together it won't go away by itself and there is not much change to wait.. I now realise how wrong she was.

So if anyone out there experience this same error, try topping up the AdBlu tank ~10L and taking the car for a good 10mi ride and waiting a few days :) .

I have never seen anything about a new design of Adblue tank, but there has been a recall to replace the tank cap. If anyone out there has not taken their Adblue fitted car to Citroen in the last 2 or 3 years, it may be worth getting the cap checked, as the old cap may be contributing to the Adblue pump failures. Should be free.

Hi all

First time poster here but this thread has been very helpful, so thank you in advance.

I have experienced similar problems to what many have described above - AdBlue top up light came on and I was going to get around to sorting that out later this week, I still had 750 miles before start being prevented and has never been an issue in the past when I have filled up.

Earlier this evening the emissions fault and engine fault light came on in the same way as everyone has described above, I immediately filled up with AdBlue and also did all the usual checks. Later the lights are still on and I'm hoping that I don't need to take my Cactus to the garage. I have a 65 plate 1.6 Diesel.

I have noted that the part number I have on the tank itself seems to be the newer one (ending 780) but also noticed that the cap on the actual tank itself is of the older variety. I have ordered a new cap for the tank directly from a dealer online for £20, rather than the hassle of chasing a Citroen dealer for one.

Here's hoping that the new cap and what everyone has posted above does actually sort the problem. :D

Hi, did the replacement of the new cap do the job?

Part of the issue here is that all Adblue caps should have been replaced under recall. As this is not a safety recall it is left until the car goes in to Citroen for service. If you don't take your car in for regular service then the issue will not be found. It is all very well saying that the servicing can be carried out by any garage as long as they use Citroen parts, but they do not have access to the database to find issues like this. The potential issue is that the cap may initiate the problem with the Adblue tank, but once the pump has failed, changing the cap is too late. So if there is anyone else out there who has, or suspects that they have the original design, I would suggest getting it sorted asap. It will should cost nothing and it could potentially save you a lot of money and grief.

Hi
I’m a not so proud owner of the useless cactus, I’ve had same problem with mine , all three lights come on I took to garage but was told would cost a fortune to fix so I found on this forum that people had replaced the ad blue cap and so I tried that and to my amazement it actually worked for two weeks then dam it was on way to work and all three lights came on again 🥵🥵🥵 so angry ! So drove all the way home then four miles away from home the urea light started to flash saying I had 700 miles left , which is rubbish as I added 10ltrs just two weeks ago,, so have booked into garage again just waiting for the bad news... this car is a joke

I'm struggling to understand (and I do have a fair bit of car DIY knowledge) how something as simple as a blue plastic cap can have such an effect, cause multiple lights to illuminate and potentially end up costing a fortune? What purpose other than stopping urea spilling all over the boot area does the cap serve? It has no wires so is not a sensor!? Does it have magic powers, lol?

I still have all 3 lights illuminated on my car. In a way lockdown has saved me a potential fortune because these lights first illuminated in late February and since then I have driven less than 500 miles. The countdown is currently on 300 miles before starting will be prevented. It is, however going into my local garage (not dealership) on Friday for them to diagnose (once more - Evans Halshaw did it in July) and hopefully get to the bottom of it.
One thing I am not going to do is throw money at garages as they replace part after part at my expense until they finally hit the button.
Evans Halshaw said it was the Nox sensor (but which one?) so I think that will be the first port of call for my local garage.

Good job I didn't go to France this year, as planned, in the car, or we'd have been screwed.

It is as simple as the old cap had no one way valve on it and the new one as , so the pump in the tank was pumping with a vacuum created inside of the tank , so had to pump very very hard, with the new cap this as eliminated the vacuum
