DIESEL INJECTION
Fault finding – Test13B
TEST4
CONTINUEDTurbocharged air inlet circuit check
Check that there is no leak at the exhaust manifold, in particular at the exhaust manifold/turbocharger connection.
Check the exhaust, run Test 1 Exhaust pipe check.
Carry out the necessary repairs.
Visually check the EGR circuit sealing.
Note:
The operational clearance of the EGR exchanger flap shaft leaves slight traces of a black substance due to
inconsequential leakage. Do not replace this part.
– Check the condition of the intercooler:
– clogging,
– leaks (vehicle stationary, stabilise the engine speed between 3500 rpm and 4000 rpm and check that there are
no leaks).
Replace if necessary.
Check that the turbocharging pressure sensor take-off point is not blocked.
Carry out the necessary repairs

TEST10
CONTINUED 2
Run SC031 Cylinder operational fault
finding.
Is SC031 correct?
The injectors are operating correctly.Check the engine compressions: use a compression
gauge, M9R hose end piece, part no. Mot. 1772 and apply
command VP036 Fuel supply inhibition (see
Interpretation of commands).
Run compressions on all cylinders.
Are the compressions correct?
Check the cylinder block.Check the fitting of the injector concerned and repair if
necessary.
Otherwise change the injector concerned.
After replacing the injector, follow the injector code
programming procedure (see Replacement of
components), run SC036 Reinitialise programming, and
select the number of the injector replaced.
Repeat Part B of Test 10 to confirm the repairs.
IMPORTANT:
When removing / refitting injectors, follow the cleanliness and safety instructions (see MR 395 (Laguna II ph2),
402 (Vel Satis), 405 (Espace IV Ph2), 364 (Megane II ph2), 370 (Scenic II ph2) Mechanical, 13B, Diesel
injection, Diesel injectors: Removal - Refitting).NO
