Check the conformity of the injectors fitted to the vehicle in relation to the type of vehicle and engine number (low,
high or very high pressure injector).
Check that the C2I* is entered correctly in the injection computer.
Check the accelerometer shielding on connection TB1 of component 120.
Check that the accelerometer is secured on the engine.
After retightening the accelerometer, be sure to clear the pressure regulation adaptives using command
RZ004 Pressure regulation adaptives.
Carry out a road test to check if the fault is still present.
If the fault is still present, replace the cylinder 2 injector, component code 194 (see MR 364 (Mégane II), MR 370

The fault is present with the engine idling.
Special notes:
When fault DF028 occurs, the idle speed is locked at 1000 rpm, there is engine noise,
the engine speed is unstable, the engine performance is reduced to 75%, the level 1
warning light illuminates, and the message Check injector is displayed until the next
time the ignition is switched off.

Switch off the ignition and wait 15 seconds.
Check the connection and condition of the cylinder 3 injector connector, component code 1954.
Check the connection and condition of connector B (48-track) of the injection computer, component code 120.
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Run command AC007 Cylinder 3 injector.
If injector 3 cannot be heard operating five times in a cycle, connect the wire of the cylinder 4 injector to
the cylinder 3 injector and run command AC008 Cylinder 4 injector.
Does this injector actuation cycle work?
Note:
If the wires cannot be swapped, continue the procedure by replying YES to the previous question.
