Hi everyone ive recently had my urea or adblue lights come on, so after plugging in my fault code reader it said reductant pressure to low, this means either the adblue injector needs replacing or the tank itself , luckily it's still under warranty, so I took it to the garage and citreon are aware of the issue and are replacing them free of charge but only when the fault occurs. I hope this helps anyone with this problem.

This is a very well known issue on diesels on all Citroen sites. I had this fault in 2017 when the scale of the issue was just becoming apparent. For others, the alarms for the Adblue system are not always due to pump failure but may be due to exhaust sensors failing or wiring loom issues. This shows why I believe it essential to maintain a Citroen warranty, as this repair would cost in excess of £1000.
