The "emergency" mode is an alternate program that is activated when the diagnostic system detects a failure that could compromise the emission control system ... This TA program gives a minimal vehicle maneuverability so you can take it to the repair workshop. If the fault is not repaired, it will not leave the support mode; I do not advise you to make bridges, you could damage the ECM
check the pipe that the exhaust multiple with the EGR valve as sure that is covered with carbon and also clean the tube that connects the EGR with the multiple of admission, if the fault is repaired after three complete cycles of handling the ECM automatically detects that in the EGR system there are no problems; will turn off the indicator a thousand and leave the backup program. If you need more help, let me know
greetings
