urea warning light

yesterday whilst making a short journey i got the Urea warning on so i topped up with a 1.5 ltr bottle but it remained on so i added more. on my way back home ( approx a 3mls journey ) i noticed the UREA warning dissappeared. i have now an engine management light on. the car is still driving perfectly so i am bewildered as to whats going on. its a 1.6 DS4 BLUEHDI

My handbook says that if the car has run out of adblu you should put 3.8litres in. I think it goes on to say you should also leave the car alone for a while before switching on the ignition, page 256 is the one
