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.

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.

Note:
If the fuel filter is to be reused, fit blanking plugs
to the fuel supply pipes and fuel filter openings,
using the appropriate blanking plug kit, depend-
ing on the engine (see 13B, Diesel injection,
Diesel injection: Precautions for the repair,
page 13B-1) .
WARNING
Do not remove the blanking plugs from each
component until the last moment.
Also, do not remove the components from their
packaging until they are to be fitted to the vehi-
cle.
Note:
Chec k that the fuel filter is correctly positioned
and secure on its mounting by shaking it: the fil-
ter must not move.
WARNING
Prepare for the flow of fluid, and protect the sur-
rounding components.
