Check the sealing of the low pressure and high pressure diesel fuel circuits (visual inspections): on the pump
casing, overpressure valve, pipes, rail and injector unions, injector wells, etc., run TEST 1 Low pressure circuit
check and TEST 7 High pressure circuit sealing check.
If all the above checks are correct:
With the vehicle ignition on and the engine stopped for over 1 minute:
Display PR038 Rail pressure, if the value is less than 30 bar, the sensor is correct.
Otherwise, use commands AC005 Cylinder 1 injector, AC006 Cylinder 2 injector, AC007 Cylinder 3 injector,
AC008 Cylinder 4 injector in order to release any residual pressure.
Check that the value of PR038 decreases. If PR038 becomes less than 30 bar, the sensor is correct.
If the fault is still present, replace the rail pressure sensor, component code 1032 (see MR 364 (Mégane II),
