Continuation for Both Cylinder Banks: 

Audi S6/RS6/RS7: 

-- Remove the radiator, with the fan shroud. Refer to RADIATOR, REMOVING AND INSTALLING .

Audi S7: 

-- Remove the fan shroud. Refer to FAN SHROUD, REMOVING AND INSTALLING .

Continuation for All Vehicles: 

-- Position the :T40272  onto the :T40263  .

-- Attach the adapter to the bolts on the vibration damper.

• The semi-round countersink -arrow A- on the :T40272  must face the semi-round countersink -arrow B- on the vibration damper.

-- Turn the crankshaft to "TDC" in direction of engine rotation in direction of -arrow-.

• The threaded holes -arrows- in the camshaft must be visible through the openings in the camshaft housing that were previously sealed with the sealing plug.

Cylinder Bank 1 (Right): 

-- If necessary, turn the crankshaft slightly back and forth to insert the :T40264/1  into the right cylinder head and tighten -arrows-.

• Tightening specification 12 Nm.

Cylinder Bank 2 (Left): 

-- If necessary, turn the crankshaft slightly back and forth to insert the :T40264/2  into the left cylinder head and tighten -arrows-.

• Tightening specification 12 Nm.

TIP: 

• If the camshafts threads do not point exactly upward, the bolts from the Camshaft Lock : T40264/2  cannot be installed.
• In this case place the Wrench - Camshaft:T40269  on the camshaft adjuster and turn the camshaft slightly back and forth.

Continuation for Both Cylinder Banks: 

-- If necessary, turn the crankshaft slightly back and forth to insert the :T40264/3  by hand into the vibration damper opening and all the way into the cylinder block.

Cylinder Bank 1 (Right): 

-- Press the right camshaft timing chain tensioner guide rails in as far as the stop using a screwdriver -1- and secure the chain tensioner with a :T40071  .

Cylinder Bank 2 (Left): 

-- Press the left camshaft timing chain tensioner guide rails in as far as the stop using a screwdriver -1- and secure the chain tensioner with a :T40071  .

Continuation for Both Cylinder Banks: 

-- To counterhold, attach the :T40269  to the relevant camshaft adjuster and loosen the bolt -1-.

-- Mark the installation position of the camshaft adjuster with paint for installation later.

Cylinder Bank 1 (Right): 

-- Remove the bolts -1 and 2- and remove both of the camshaft adjusters.

-- Remove the camshaft timing chain from the gliding piece.
