Citroen DS3 adblue light, low emission, engine light, service light
Variant: 1.6
Model Year: 2015
Same thing as was previously posted (see below) happening to me. Very annoying! Anybody know any useful info? TIA.
Adblue light on, along with engine light. Topped up adblue but no warning sign to say it was low at 1,500miles which it normally does. Taken it to two garages both have said there is nothing coming up on the computer apart from adblue low. ive put 10litres in it so it isn't low. I've done alot of research into this so has the garages and we have found a "common fault" the sensor is placed inside the tank so when that is faulty you have to replace the tank costing just under £1000 for the tank alone. My research and also the garage has found This is common in ds3 after 2-3years. This is no wear and tear on these cars it's a common fault. Why are paying customers being made to pay for a fault in the car? I also had a quick chat with a sales man who tried selling me a car rather than helping me with my problem and actually agreed that it is common and they don't know why citreon has decided to put the sensor inside the tank!! Answers are needed immediately by citreon!

I believe this is a known fault, the Adblue tank is sealed but with a vent to allow air inside the tank as the Adblue is consumed. The vent is the problem , not allowing air into the Adblue tank and the tank breaks. i believe Citroen are replacing Adblue tanks which have failed as a warranty issue. The new tanks have a better venting system

With regard to the Adblue systems, the earlier systems had teething problems - the tanks for example had a lot of metal components inside which over time, were adversely affected by the UREA solution causing corrosion and blockages. So the newer tanks were changed to incorporate more plastic components to prevent this. A lot of these tanks were replaced under warranty within the 3 years / 60k miles or equivalent, but in a lot of cases, PSA made some varying contribution to replacing these when they were out of warranty depending if the car had been serviced properly of course. So that is an example of where they have improved these.
Another was the unvented cap - which could hinder the pump from working correctly and cause it to break down - requiring a complete tank replacement because of the reasons already mentioned. A vented cap was introduced on affected models to solve that.
Then there was the issue of the NOx sensor harness wiring getting cut / burned through leading to the engine thinking the Adblue tank was empty and preventing engine starting.
