Is status ET563 Flow capacity function
"ACTIVE"?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 condition of the computer connections
(for bent pins, signs of oxidation, silicone, etc.) and
check that the computer connectors lock correctly.Check the diesel filter.
Is it close to the replacement mileage?
Contact the Techline if the customer complaint is
still present.
Replace the diesel filter (see MR 388 (Logan/
Sandero), MR 451 (Duster), MR 423 (Thalia 2/
Symbol 2) or MR 374 (Kangoo VLL),

Check that the turbocharger is working properly.
Run TEST 11 Air line at the turbocharger.
Run TEST 10 Turbocharger solenoid valve check.
Run TEST 12 Turbocharger.
Check the low pressure circuit by running TEST 1 Low pressure circuit check.
Check the injectors by running TEST 3 Injector check.
Check the high pressure pump by running TEST 6 High pressure system check.
Is the compression in order?
Is the valve clearance set correctly? Carry out the necessary repairs.

ALP12 Too much power
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
In this case, the control solenoid valve is jammed: it is possible to increase the vacuum but not reduce it
afterwards.
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
Check the air inlet circuit by running TEST 5 Inlet circuit check.
Check that the engine has not sucked up its oil (engine racing).
Check that the turbocharger is working properly.
Run TEST 11 Air line at the turbocharger.
Run TEST 10 Turbocharger solenoid valve check.
Run TEST 12 Turbocharger.
Check the condition of the computer connections (for bent pins, signs of oxidation, silicone, etc.) and check that
the computer connectors lock correctly.

In this case, it may be the solenoid valve dynamic specification which is at fault (atmospheric pressure
resetting time). Final fault finding is carried out by measuring this specification on a special bench.
Check that solenoid valve casing does not have any splashes of fluid on it which may impede the breather (water,
engine oil, gearbox oil, brake fluid, coolant, mud, dust, or any other substance).
Instructions:
The solenoid valve must be set up 450 mm above the ground, in an area free from water, mud, or any other fluid.
Cleaning with a high pressure jet is forbidden.
Is there coolant present?
Is the solenoid valve subjected to significant fluctuations or impacts?
Instructions:
The solenoid valve must be correctly secured to its mounting.
Contact with the engine environment is forbidden.Follow the
recommendations below.
Check the turbocharger regulation control (no
partial jamming, etc.).Follow the recommendations below.

ALP 13 Excessive consumption
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Check that the fuel tank is correctly filled and that the appropriate fuel is used.
Apply TEST 13 Diesel fuel conformity check.
Check the levels of engine oil and coolant.Replace the fuel temperature sensor (see MR
388 (Logan/Sandero), MR 423 (Thalia 2/Symbol
2), MR 451 (Duster) or MR 374 (Kangoo VLL),
Mechanical, 13B, Diesel injection, Rail pressure
sensor: Removal - Refitting). Is the fuel temperature sensor leaking?
Check the low pressure circuit by running TEST 1 Low pressure circuit check.
Visually check that there are no leakages on the high pressure circuit by running TEST 7 High pressure circuit
sealing check.
Check the air inlet circuit by running TEST 5 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
