ESSENTIAL : Observe the safety and cleanliness recommendations .

ESSENTIAL : All personnel carrying out work on a vehicle fitted with traction batteries must have received specific electric vehicle training and be authorised to work on these vehicles (observe the regulations in force in the respective country).

1. Parts which must always be replaced

Description	Quantity
Seal of the inlet camshaft variable timing actuator	1
Seal of the exhaust camshaft variable timing actuator	1
Motorised throttle housing air inlet union seal	1

2. Location

(1) Inlet camshaft variable timing actuator.

(2) Exhaust camshaft variable timing actuator.

3. Preliminary operations

CAUTION : Perform the operations that are required prior to a disconnection of the ancillaries battery .

CAUTION : In the case of a vehicle with 2 batteries, carry out the specific operations for disconnecting and reconnecting the ancillaries batteries.

Disconnect the ancillaries battery or batteries (depending on equipment).

4. Removing

Slacken the clip (6).

Remove the bolt (5).

Unclip the clips (at "a").

Move aside the fuel supply pipes (3), (7).

Remove :

• The motorised butterfly housing air inlet union (4)
• The motorised throttle housing air inlet union (4) seal

Disconnect the connectors (at "b", "d").

Unclip the electrical harness ‎ sheathing ‎(8) (at "c") ; Using a Torx spanner with extension.

Move aside the electrical harness sheathing (8).

CAUTION : Protect the surrounding area using a cloth on removal to absorb the oil which flows out of the opening.

Remove :

• The bolts (9), (10)
• The inlet camshaft variable timing actuator (1)
• The exhaust camshaft variable timing actuator (2)

Remove the seals (11).

5. Refitting

CAUTION : Observe the tightening torques .

CAUTION : Clean the sealing zones of the variable timing actuators (1), (2) and check that there are no impacts or scratches.

CAUTION : Lightly lubricate the new seals (11).

CAUTION : The bolts (9), (10) are not always replaced with new bolts ; If the bolts (9), (10) are reused, clean the thread and apply thread lock product.

Refit :

• The inlet camshaft variable timing actuator (1) (equipped with a new seal)
• The exhaust camshaft variable timing actuator (2) (equipped with a new seal)
• The bolts (9), (10)

Attach the electrical harness ‎ sheathing ‎(8) (at "c") ; Using a Torx spanner with extension.

Reconnect the connectors (at "b", "d").

CAUTION : Do not clean the grease in the air inlet union of the motorised throttle housing (at "e").

Angle "A" = 45°.

CAUTION : To avoid twisting the new seal (12) of the motorised throttle housing air inlet union (4), tilt the air inlet union (In accordance with the angle "A").

Refit :

• The new seal (12) of the motorised throttle housing air inlet union (4)
• The motorised butterfly housing air inlet union (4)
• The bolt (5)

Tighten the clip (6).

Refit the fuel pipes (3), (7).

Clip the clips (at "a").

6. Additional operations

CAUTION : Perform the operations that are required after reconnecting the ancillaries battery .

CAUTION : In the case of a vehicle with 2 batteries, carry out the specific operations for disconnecting and reconnecting the ancillaries batteries.

Reconnect the ancillaries battery or batteries (depending on equipment).
