–Check the cleanliness of the air filter.
–Replace the filter if necessary.
–Check that the air inlet circuit is not blocked.
The turbocharging system must be perfectly sealed, from the exhaust manifold to the turbocharger, from the
turbocharger to the heat exchanger and from the heat exchanger to the throttle valve.
Check that there are no air leaks:
–around the turbocharger pressure sensor,
–around the air temperature sensor.
Check absence of leaks in the wastegate capsule pressure circuit connected to the turbocharger system.
Check that the air-air heat exchanger is not clogged (presence of oil).
If there is oil in the heat exchanger, the turbocharger is certainly damaged.
Using a pressure/vacuum pump, check that the turbocharger protection and turbocharging valve capsule
diaphragms do not leak.
Check the condition the motorised throttle valve in terms of clogging.
