Malfunction of the SCR 
emissions control system
Malfunction detection
If a malfunction is detected, 
t hese warning lamps come on, 
accompanied by an audible signal 
and the display of an "Emissions 
fault" message.
The alert is triggered while driving as soon 
as the fault is detected for the first time, then 
when switching on the ignition for subsequent 
journeys, while the fault persists. If it is a
  temporary fault, the alert 
disappears during the next journey, 
after self-diagnostic checks of the SCR 
emissions control system.
Malfunction confirmed during the 
permitted driving phase (between 
685
  miles and 0   miles (1,100   km and 0   km))
If the warning lamp is still on after 31 miles 
( 50   km) of driving, the fault in the SCR system 
is confirmed. Have the system checked by a
  CITROËN 
dealer or a   qualified workshop as soon as 
possible.
Starting prevented
Every time the ignition is switched on, the 
message "Emissions fault: Starting prevented" 
is displayed.
To be able to restart the engine, call 
on a
  CITROËN dealer or a   qualified 
workshop.
The AdBlue warning lamp flashes, 
accompanied by the display of a
  message 
("Emissions fault: Starting prevented in x 
miles") indicating the remaining range in miles 
or kilometres.
While driving, the message is displayed every 
30
 
 seconds. The alert is repeated when 
switching on the ignition.
You can continue driving for up to 685   miles 
(1,100   km) before the engine star ting 
prevention  system is triggered.
