Continue fault finding, regardless of whether or not the fuel return rail has been replaced.
For the other specifications, move on to the next step.
If the loss of power was not noted during slight acceleration and if there was a loss of engine power during each
acceleration at full load, replace the diesel fuel injector return rail and its overpressure valve (see MR364

Mechanical, 13B, Diesel fuel injector return rail: Removal - Refitting).
Check the condition of the turbocharging pressure sensor connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1071).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,

Test the high pressure fuel circuit:
Apply scenario SC035 High pressure fuel circuit fault finding.
To interpret the result, apply the interpretation of command SC035 (see Interpretation of commands).
With the engine stopped and ignition on, view parameters PR035 Atmospheric pressure and PR041
Turbocharging pressure.
If there is a difference of > 100 mbar, check that the atmospheric pressure reading is consistent (by comparison
with another vehicle for example).
If atmospheric pressure is consistent, replace the turbocharging sensor.
If not, contact the Techline.
Use the Monitool application: MT001 Turbocharging function to check the entire air line (only for Vdiag 04 and
44).
Apply Test 4 Turbocharged air inlet circuit check.
Run Test 7 Variable geometry turbocharger control.
Run Test 8 Turbocharger rotating part.
