-- Oil the control valves -1 and 2- on the threads and the control valve contacts surface and install loosely.

• Both camshaft adjusters must be able to be turned on the camshaft.

-- Remove the Locking Pins :T03006  .

• The help of a second technician is necessary for the following step.

-- Have a second technician tension the Electronic Torque Wrench 3-60Nm :VAS 6583  with insertion adapter Hazet 6423C or Torque Wrench Adaptor :7370/10  with Torque Wrench Insert - Ring Tool Attachment AF41 :VAS 261 001  and Counterholder : T90001  on the intake camshaft adjuster to 26 Nm counter-clockwise -arrow- and hold.

• Pretension torque without using the insertion adapter Hazet 6423C or Torque Wrench Adaptor :7370/10  is 30 Nm.

-- Tighten the control valves with Socket E24 :T90000  as follows while the camshaft adjuster is still being held under tension:

• Control valve -2- on the exhaust camshaft 30 Nm.
• Control valve -1- on the intake camshaft 30 Nm.

Valve Timing, Checking

-- Remove the Camshaft Positioning Tool :T40331/1  .

-- Remove the Camshaft Lock :T40264/3  or Crankshaft Locking Pin :T40069  .

-- Using the Wrench - 21mm :T40263  and Adapter :T40314  , turn the crankshaft two turns -arrow- until the vibration damper is back at "TDC".

Procedure, if the engine is NOT removed due to preliminary work.

-- Install the Camshaft Locating Tool :T40264/3  at the vibration damper opening all the way by hand into the belt pulley side sealing flange. If necessary, move the crankshaft back and forth slightly to center the bolt.

Procedure, if the engine is removed due to preliminary work.

• Do not use a hammer to install the camshaft positioning tool.

-- Insert the prepared Camshaft Positioning Tool :T40331/1  all the way in the camshaft.

• The Camshaft Positioning Tool :T40331/5  engages as shown in the upper asymmetrical groove -1- on the exhaust camshaft.
• The Camshaft Positioning Tool :T40331/6  engages as shown in the flattened section -2- on the intake camshaft.

If the Camshaft Positioning Tool :T40331/1  CANNOT be Inserted:

-- Remove the Camshaft Lock :T40264/3  or Crankshaft Locking Pin :T40069  .

-- Insert the prepared Camshaft Positioning Tool :T40331/1  all the way in the camshafts as previously described. For this turn the crankshaft slightly.

-- Loosen the control valves -1 and 2- a half a turn using the Socket E24 :T90000  .
