DIESEL INJECTION
Fault finding – Test13B
TEST11 Temperature upstream of turbine too low
Perform a complete fault finding of the
injection computer using the diagnostic tool.
Are there any present or stored faults?Apply the procedure for dealing with the
associated faults.
Run Test 1 Exhaust system check
Is the exhaust pipe correct?
Repair then carry out another particle filter
regeneration.
Run command SC017 "Particle filter
regeneration" (see Interpretation of
commands).
If the second regeneration is successful, it is
essential to change the engine oil and replace
the oil filter.
If the second regeneration fails, contact the
Techline. Apply Test 4 Turbocharged air inlet circuit
check.
Is the inlet circuit in order?
Run Test 4 Air flowmeter
Is the air flow sensor correct?
Run Test 10 Poor injector operation
Are the injectors correct?
Contact the Techline.

DIESEL INJECTION
Fault finding – Test13B
TEST12 Diesel fuel conformity check
WARNING
During this operation, it is essential to:
– refrain from smoking or bringing incandescent objects close to the work area,
– guard against petrol splashes caused by the residual pressure in the pipes,
– wear safety goggles with side guards,
– wear leaktight gloves (Nitrile type).
IMPORTANT
– To avoid any corrosion or damage, protect the areas on which fuel is likely to run.
– To prevent impurities from entering the circuit, place protective plugs on all fuel circuit components
exposed to the open air.
Preparations:
Weigh an empty 1300 ml plastic cup (part no. 77 11 171 413) with its cover (part no. 77 11 171 416) using
electronic scales such as those used in body paint workshops (example: PANDA part no. 77 11 224 995). Record
the weight of the empty plastic cup.
This type of plastic cup is used to prepare paint.
Remove 1 litre of fuel from the diesel fuel filter outlet (see MR395 (Laguna II ph2) or MR402 (Vel Satis ph2)
or MR405 (Espace IV ph2) or MR364 (Mégane II ph2) or MR370 (Scénic II ph2), Mechanical, 19C, Tank, Fuel
tank: Draining), using a pneumatic transfer pump (part no. 634-200) and place it in the 1300 ml plastic cup.
Cover the plastic cup with its cover and let it settle for approximately2 minutes.
Is the fuel cloudy or does it
separate into two parts?Presence of water in diesel fuel, the fuel is not compliant.
Drain the fuel circuit, including the tank (see MR395 (Laguna II
ph2) or MR402 (Vel Satis ph2) or MR405 (Espace IV ph2) or
MR364 (Mégane II ph2) or MR370 (Scénic II ph2), Mechanical,
19C, Tank, Fuel tank: Draining).
