Emissions fault!!!

After nearly 6000 miles first the engine warning light then the urea warning light came on :x Then it started counting back from 750 miles to say the engine would not start :( I got it down to 600 miles before I got it to a dealer. The dealer couldn't deal with it for two days and then on the day said his diagnostics computer was down :eek: :eek: :eek: So he just topped up the Blu ( there is no level indicator) and reset the fault :evil:

I'm back on the road but I'm nervous about what will happen next :oops:

I suppose the best spin I could put on it is that the Blu was never properly topped up when the car was delivered as it is supposed to last 12500 miles.

Any other suggestions?

k. so the C4GP tank has different size than Cactus but uses same pump/level detector/injector
so 9818559280/9808378080 is for the C4GP.
9812914780/9818703780 for cactus
the problem here is a manufacturer will not change the part unless it think there is a reason.
regarding the tank: it supposed to sustain 6bar pressure since it designed to work in some vacuum.
its very easy to test the tank is sealed . not high tech gear. every garage has the tool.
and yes, the fact that it is plastic makes it vulnerable to deformation (from hot asphalt).

I had the same issue, it required a new adblue reservoir and injector replaced under warrantee.

In my opinion, for a new vehicle, my car has had too many recalls from Adblue, bonnet lock, catalytic converter, new rear doors, new rear brakes (discs) paid by me, air-conditioning (several faults), paintwork, drive-shaft seal, and no doubt a few more I have forgotten to mention.
It is just under 4 yrs old 34,500 miles. :(

The safety recalls register available on line at the DVSA web site( https://www.dft.gov.uk/vosa/apps/recalls/default.asp ) shows that over the period April 2014 (Cactus release date) to August 2018, many different Citroen models (not just the Cactus) have needed safety modifications/ rectification work.
In addition of course there have been other issues such as paint work, whistling door seals, leaking washer pipe work etc.

Its a sad reflection on the design capability and production quality control of a long standing car marque.

My son has spent most of the last year getting BMW to resolve build quality issues on his £40K+ M240i, including such minor things as no paint where there should be, painted over dirt on the boot lid and rear bumper, faulty leather paint on the drivers seat, and more. He won't but another BMW, and he's negotiating with BMW directly for a refund so that he can go elsewhere. The point is, issues happen with all manufacturers, and my experience with Citroen is that when there's an issue they fix it willingly (at least through my dealer Wilcox's in Wickwar), whereas the premium brands (=ripoff for an in-fashion badge) are usually the most difficult.

I may change brands next year because I wanted a new Cactus but I don't like the facelifted one. And I'm indifferent to all the standard Euro-cars in the range, including the DS range.

Your right there about big brands,freelander 2001 worst car ever ,head gaskets,not 4 wheel drive and everything else broke,2008 audi A4 2.0tfsi drinks oil at 1 litre every 600 miles,both times excuses excuses ,audi then on tv about it ,citroen however (my dealer Birmingham) quick to respond and repairs no problem (and to high standard),still good car , still interesting look to MK1 cactus.

Hi everyone, just to give some info about my Citroen. Engine warning light came on a few weeks ago, then a few minutes later service and urea light. Have car repaired warning and won't start in 1500 miles warnings, which were a real pain. I topped up with adblue but lights stayed on even after a few days. I bought OBD2 and it said p20e8 and p204e, low reductant pressure and wiring sensor fault. I booked in with Citroen for the two recalls. By the time it came round most of the warnings had stopped but p20e8 was still showing. All dashboard warnings had gone, without doing anything (except for the adblue top up, only 6 litres). Citroen changed adblue cap and checked catalytic and said there were no faults showing. I've driven a few times and seems fine. Also one thing that came up while i was looking into it was dpf regeneration at high ish speed. Anyway, i don't know if my car is all better for sure but all i would say at moment is get those two recalls, especially adblue cap before spending too much on anything else. I was worried from what I'd read that i might need to spend a lot having adblue tank and pump changed but so far that doesn't seem to be required, cheers, Wayne

Thanks Wayne - good detailed info.

Hi Wayne

Exact same thing happened to me just after Christmas. Filled with ad blue but none of the lights went off. Couldn't get it into garage until yesterday and they've come back saying its the NoX sensor. Apparently I'd already had the ad blue recalls on a previous visit (New recall was done on the steering wheel controls though) They have reset the warning count down and no dashboard lights now but apparently it could come back on at any time and give me a 750 mile count down to non starting. They want £400 to replace the sensor but I'm reluctant due to the "might" not come back on. Is your car still OK?

Thanks
SJ

Hi Sj and Wayne's and all.

Same has just happened to my cactus. It happened last week and then went off. I dont seem to have the 750 mile warning though. Going to have the adblue topped up although I know it was topped up at xmas.

This is after alot of issues after buying the car last September. I believe I had the adblue tank replaced by the garage i bought it from.

Has anyone had this problem and how was it resolved. I have owned landrovers previously and my cactus is getting to their level of unreliability!

Matt

Same issues here and not very happy!

Absolutely love the car (minus faults) I'm a commuter so I do expect the service light to come on more frequently.
This is what happened to my 2014 Cactus C4 Blue HDI:

My UREA and service light came on in Dec 18. No problem, I ended up taking it to a quick-fit and had a full service as dealer couldn't fit me in.
All lights off. Within 2 days the engine warning light came on. I called the dealer who told me to take it back to quick-fit. They denied all knowledge and said it was something to do with emissions on the diagnostics.

It was due MOT end feb and as I was going to be out of the UK took it to a local garage. Failed MOT because the engine light was on 😡

Mid Feb 19 Booked it into the dealer and paid circa £500 for replacement de-nox sensor, and MOT.
All lights off and good to go again.

Last week Service light on again, Within a few days UREA light and engine light came on in unison with the 700 m warning.
I bought 5l adblue 2 days ago and put about 3l in. Within 10mibs of driving, UREA light goes off still have the engine and service lights on.
An hour later UREA light back on.

Slightly worried as this is exactly what happened in Feb (2 months ago)! with the engine light. No warrunty.

Will get it booked in after the Easter w/e.

Just found this thread, I had this issue on a C4 Grande Picasso about a year ago. In my case the Adblue warning came up, but no countdown. I have had many other issues, all of which, except a new battery after the stop/start failed to function, have been free under warranty. From my experience I would urge anyone who has a car under 3 years old which has been correctly serviced within the Citroen dealership network to consider the Citroen extended warranty. It is less than £300 for a year, and could save you a fortune. You must take it out before the original warranty expires, and can be renewed each year, again without the previous year's warranty expiring. You can renew unless the mileage has exceeded 100,000 miles. I had two claims on our C3 , one at about 95,000 miles (injector) and one at over 100,000 miles (ABS sensor)

Buy a lexia/diagbox-tool - go under repair/BSI/manual configuration/Engine and tell the car that the denox-system is off ("presence of a nitrogen oxide reduction system - NO") - voila, no more failures. And hey - listen climate-dudes, I dont care about the climate under this circumstances because citroen/PSA messed all this Adblue-tank-system totally up. Blame them if you think I polute more now. MOT dont see the changes cause they cant measure it, and there is no light in the panel.

Next time I buy a Golf II from 1989.

I guess its my turn to complain about the adblue problem..

A few months ago the UREA light came on along with the engine fault warning. Picky as i am i stressed right out especially after noticing it actually said "engine fault", however, next day im back on the road and engine fault warning disappears, and then the next day the urea light also disappeared.

This happened a few more times (like 4 or 5) engine warning and urea light came on, then disappeared a few days later. I went to my local dealer and repair shop and i asked about this and more importantly, i asked if citroen actually takes any responsability for the problem (you know, money wise) and they said they were not sure about that, they'd have to look into the problem.. at that point im like "yea ill just pray for it to disappear again.." which funnily enough did but a month ago the urea light came back on again, filled up the adblue tank but nope, car aint having none of it..

Im guessing i gotta take the car to the citroen repair shop again and im just gonna hit every fb and ig citroen post with bad publicity explaining my issue, because nowdays brands care more about appearances and dont give a damn about its customers.. hopefully they will recognise the problem as a factory defect because ive seen a lot of people with the same exact problem for it to be a coincidence.

Cheers.

I'm having exactly the same problem. Engine light and Urea light came on and a message to say there is an emissions fault. The urea light goes off but the engine light stays on and service also pops up. I haven't had a countdown on miles yet. I'm taking it to Halfords who will top up my AdBlue so I'm hoping that will solve the problem.

I part exchanged my old Ford Fiesta Style for this. I never had a problem with that car. Wish I'd stuck with it :(

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.
