For air pipes made up of several components:
- mark (10) the fitting position of each component,
- separate all the components.
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 that the cleaning product has drained out
completely (check areas where liquid may be retai-
ned: gaiters, resonator, etc.).
Dry the pipes one by one using a compressed air gun.
For pipes comprising several components:
- assemble the components, taking note of their correct
fitting position (10) .

charger) (A) ,

Refit the intercooler, if fitted to the vehicle (see 12B,
