I - TURBOCHARGER: GENERAL INSTRUCTIONS
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,
page 10A-29) .
-Replace the seals and fittings,
-Carry out the following only if the compressor wheel is
broken or rubbing against the turbocharger casing:
•Drain the intercooler, Equipment required
par ts washer
WARNING
The turbocharger pressure regulator rod must not
be adjusted.

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,
Turbocharging, Intercooler: Removal - Refitting,
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.
112771
Note:
(**) These instructions relating to the lubrication cir-
cuit must always be followed in all cases of
mechanical damage as listed above.
WARNING
Failure to observe the following procedure may lead
to destr uction of the turbocharger.

Ensure that no foreign bodies enter the turbine or
compressor during the refitting operation.
Check that the turbocharger oil return pipe is not
partially or completely blocked by scale. Check
that there are no leaks. If there are, replace the
part.Note:
Dur ing this operation, use a set of feeler gauges
to ensure that there is a minimum clearance of 3
mm between the turbocharger water outlet pipe
and the turbocharger heat shield.
