For the turbocharging pressure regulator check (see
Fault finding - Tests) (Technical Note 3419A, 12B,
Turbocharging).
II - TURBOCHARGER CIRCUIT DIAGRAMIII - APPLICATION CONDITIONS OF
INSTRUCTIONS
The instructions below must be followed when repla-
cing a turbocharger due to mechanical damage:
-damage to the bearing system,
-broken shaft or turbine wheel,
-compressor wheel rubbing against the turbocharger
casing,
-broken or damaged compressor wheel,
-extensive clogging of the turbine wheel casing (hard
deposits).
FOR THE AIR CIRCUIT:
-Consequences:
•swarf or metal objects in the turbocharger inlet and
outlet pipes,
•oil in the air circuit (collected in the intercooler).
-Risks (after replacing the turbocharger):
•metal objects sucked in by the compressor wheel
(destruction of the turbocharger).
FOR THE LUBRICATION CIRCUIT:
-Consequences:
•swarf found in the engine oil circuit,
•circulation of swarf within the circuit.
-Risks (after replacing the turbocharger):
•premature wear on the bearing system (destruction
of turbocharger).
INSTRUCTIONS:
-Drain the engine oil (see 10A, Engine and cylinder
block assembly, Engine oil: Draining - Refilling,
page 10A-22)
-Replace the oil filter (see 10A, Engine and cylinder
block assembly, Oil filter: Removal - Refitting,

One by one, clean the pipes removed with the parts
washer :
-brush as much of the inside of the pipe as possible
(only use brushes with plastic bristles),
-wash plenty of cleaning product from the cleaning sta-
tion through the pipe,
-allow the cleaned pipe to drain by standing it upright,
-ensure the cleaning product has drained out com-
pletely (check areas where liquid may be retained,
e.g. gaiters, resonators etc.).
Dry the pipes one by one using a compressed air spray
gun.
For pipes comprising several components:
-assemble the components, taking note of their correct
fitting position (10) .
Refit:
-the air pipe(between the air filter unit and the turbo-
charger) (A) ,
-the air pipe (B) (between the turbocharger and the in-
tercooler).
Refit the intercooler, if fitted to the vehicle (see 12B,

page 12B-18) .V - LUBRICATION CIRCUIT**: INSTRUCTIONS
FOLLOWING MECHANICAL DAMAGE TO THE
TURBOCHARGER
Drain the engine oil (see 10A, Engine and cylinder
block assembly, Engine oil: Draining - Refilling,
page 10A-22) .
Replace the oil filter (see 10A, Engine and cylinder
block assembly, Oil filter: Removal - Refitting, page
10A-29) .
Only fill the engine with a suitable oil type (see Engine
oil: Specifications) (Technical Note 6013A, 04A, Lu-
bricants).
VI - GENERAL INSTRUCTIONS TO BE FOLLOWED
WHEN REMOVING A TURBOCHARGER
Always replace:
-the oil supply pipe:
•if the pipe is blocked, even partially (due to scale,
carbonised oil etc.),
•if the pipe is fitted with self-retaining seals.
-the oil return pipe:
•if the pipe is blocked, even partially (due to scale,
carbonised oil etc.),
•if the pipe is fitted with self-retaining seals.
-all seals that have been removed,
-all fittings that have been removed.
When starting the engine:
-do not accelerate,
-allow the engine to run for 1 minute,the time taken for
the oil circuit pressure to increase (until the oil pres-
sure warning light on the instrument panel goes out),
-accelerate several times at no load,
-check the air circuit and the oil circuit for leaks.

Note:
(**) These instructions relating to the lubrication cir-
cuit must always be followed in all cases of
mechanical damage as listed above.
