In this case, the lack of power is due to insufficient vacuum for the OCR * setpoint given.
ALP11 Loss of power
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

NOTESOnly consult this customer complaint after a full check with the diagnostic tool.
Check that the fuel tank is correctly filled and that the fuel is correct: run TEST 13 Diesel fuel conformity check.

Check the low pressure circuit: run TEST 1 Low pressure circuit check.
Visually check that there are no leaks on the high pressure circuit: run TEST 7 High pressure circuit
sealing check.
Check the air inlet circuit: run TEST 5 Air inlet circuit check.
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.

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.

ALP18 Oil leaks from the turbocharger
NOTESBefore dealing with this customer complaint, check that there are no faults,
and the conformity (or otherwise) of the parameters and statuses using
the diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
Check the area around the turbocharger
Note:
An oil leak does not correspond always to a turbocharger fault, the oil leak can arise from the area around
the turbocharger.
Depending on the vehicle type, the best visual access will be either from above or from below.
1. Do not start the engine.
Check the area around the turbocharger and identify the origin of the leaks.
Clean the oil traces on the turbocharger.
2. Start the engine and let it warm up several minutes.
IMPORTANT
If the air filter was removed previously, refit it before starting the engine (risks foreign matter entering the air inlet
circuit).
Accelerate with no load several times, progressively increasing the duration before releasing the accelerator pedal.
Visually inspect the exterior condition of the fuel supply pipes and the turbocharger oil return and the area around it.
Identify the origin of the leaks.
Is an oil leak present at the air compressor inlet or outlet?
Check the air compressor inlet or outlet
Check for a loose interface (inlet or outlet) that is the cause of the air leak.
Note:
It is normal to find oil traces inside the pipes at the turbocharger inlet or outlet,
because the air entering the compressor is laden with oil from the engine
rebreathing circuit.
Is the suspected interface properly tightened?Tighten the interface
or the concerned pipe.
End of procedure.
Replace the pipe concerned (see MR 364 (Mégane II), 370 (Scénic II), 392 (Clio III), 385 (Modus), 411
(New Twingo), or 417 (Kangoo II), Mechanical, 12B Turbocharging).
