The vehicle has entered the "Flow capacity function"
program. This function is activated more easily when:
the external temperature is high, the fuel level in the
tank is at 1/4, the vehicle is laden and if the vehicle
speed is high. Check the high pressure pump: run TEST 6
High pressure system check.
Is the "Flow capacity function"
programming active?
Check the computer:
Check that the computer connectors are
properly locked.
Check the condition of the computer
connections (bent pin, signs of corrosion,
silicone, etc.).
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.Check the diesel filter.
Has the diesel fuel filter reached its full mileage?
Contact the Techline if the customer complaint
is still present.
Replace the diesel filter (see MR 364 (Mégane II),
MR 370 (Scénic II), MR 385 (Modus), MR 392

NOTESSpecial note:
Only consult this customer complaint after a complete check with the diagnostic tool.
See explanation for flow capacity function in system operation.
There is no turbocharging control solenoid valve on New Twingo K9K 740
engines or on Kangoo 2 K9K 800 engines.
Is the "Flow capacity function" programming
active?Check the diesel filter.
Is it close to the replacement mileage?
Using the diagnostic tool, check that the injector
codes (C2I) are correctly entered on the identification
screen. If not, configure the correct injector codes
using command SC002 Enter injector codes.Replace the diesel filter (see MR 364

ALP16 Engine rattling, noisy engine, turbocharger noise
NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
If the noise arises from the turbocharger, apply Technical Note 5164A, Noise fault finding.
Note:
Pay close attention to faulty components that might result in unjustified replacement of the turbocharger.
For example, whistling does not necessarily indicate damage to the turbocharger (this could be coming from
the exhaust, the timing, the gearbox, etc.).
Check that the fuel tank is correctly filled and that the fuel is correct: run TEST 13 Diesel fuel conformity check.
Check the levels of engine oil and coolant.

Is the compression in order? Carry out the necessary repairs.
Check the electrical conformity of the heater plugs (the resistance value of the heater plug must be less
than 2 ΩΩ Ω Ω
).
Using the diagnostic tool, check that the injector codes (C2I) are correctly entered on the identification screen. If
not, configure the correct injector codes using command SC002 Enter injector codes.
