does anybody on this forum have any idea where i can get a list of fault codes & the meaning of them for a DS ds 4 . I have tried the french car forums both citreon & ds without luck, my eml is on & urea warning appeared momentarily, topped it up & it took 15ltrs to fill the tank. initially eml disappeared but has returned. i will have a look tomorrow & delete any codes, but it would be handy to know if any codes appear what they mean, :y

Assuming that you have a code reader, does it not have a DTC ‘Look Up’ function, so that if a fault code is present/active you can look it up on the code reader. :-\

cannot look it up until tomorrow . omitted to say on original post , the car running as it should.

Google is your friend Ray, itll normally de-cypher any code for you

Emissions codes are regulated and have to be standardised, so google should provide the answer.

Could that be as simple as needing a DEF refill :-\
-
Comms fail suggests either the AdBlue ECU is lacking power or has an issue (be it wiring or the ECU itself), so start by checking wiring and fuses
-
I should add that all codes should have a suffix which is missing from yours, that would tell us more :y

Update - i cleared both codes & both disappeared for 2 days , UO29D has come back & that reads as -
fault in communication with De NOX system , so will have to check that out, ( not sure where to start looking tho )
