308 t9 2016 1.6blue hdi. After refueling, the "check engine" appeared. The electrician was picking, picking, erasing errors, but after turning the key, the errors returned. In general, from what he said, there was no urea dosing. I added the urea to the top, I check it from time to time - it is decreasing. The "check engine" indicator lights up after the start, additionally the "Service" indicator on the clocks. Nothing else. Look for another electrician?
I had exactly the same case.
car in the family C3 III 2019, 1.6 bluehdi 100PS
Engine error after refueling.
It is quite easy to deduce how to know how it works that there is probably a problem with adding the additive to the fuel, because after refueling, the pump should give the liquid to the tank.
I have noticed that the problem may be:
- system response time
- pump jam
- problems in electrical connections
it all boils down to the fact that after lighting the lamp it will not go out by itself.
In Diagbox you can embrace this model through the Citroen CACTUS
Clearing the DTC itself is sometimes unresponsive.
Tests should be performed within the appendix:
pump test attention sometimes starts only some time and then it's ok.
Erases the error and that's it.
Interestingly, you can refuel several times and it's okay until it pops up again.
I bet on poor connections in the motor controller plug because it controls the pump. And I already have many cases that the plug inserts are of quite poor quality in Citroen.
For a year, it was only necessary to delete this error twice in my case.
The last time it happened - I unplugged and plugged in the plug several times and washed with the contact agent.
For now it's OK
