Removal and installation of valve 1 of the valve timing system "N₂0S"

If present, remove the boost air guide pipe to the resonator. Disconnect the connector of valve 1 of the variable valve timing system "N₂05" "1". Unscrew the "arrow" screws and remove valve 1 of the valve timing control system "N₂05".

Installation is carried out in the reverse order, observing the following: Lubricate the sealing ring and the O-ring with engine oil.

Removal and installation the upper timing chain cover

Only cars with a resonator: remove the lock "1", disconnect the fuel lines "2" and unscrew the bolt "3" to the absorber with activated carbon. Put aside the supercharged air pipe.

Cars with an absorber in the engine compartment

Remove the air duct "1", unlock the absorber "A" and lift it up "B". Put the absorber aside.

All

Press the cooling system hoses to the side and secure with binders. Unscrew the "arrow" screws, remove the dipstick guide tube from the chain drive cover.



Remove valve 1 of the variable valve timing system "N₂05". Unscrew bolts -1...5- and remove the upper cover of the chain drive.

Installation

Lubricate the O-ring and O-ring with engine oil. Tighten the bolts in the sequence shown by hand. Tighten the bolts to 9 Nm using the torque wrench -VAG 1783- and the 10 mm open-end wrench -VAG 1783/1-. Further installation is carried out in the reverse order of removal.

Removal and installation the lower protective cover of the drive target

Remove the sound insulation. Remove the front right fender liner. Drain the engine oil.

Cars with independent heating

Disconnect clamp "1" and unscrew bolt "2". Remove the muffler of the independent heater.

All

Unscrew the "arrow" bolts. Remove the air duct, for this lift the brackets -1 and 2-.

Caution: Risk of damage to previously used poly V-belt when changing its running direction. For reinstallation, mark the running direction of the poly V-belt with chalk or felt-tip pen before removing it.

Remove the right air duct hose "arrow".



To loosen the poly V-belt, turn the tensioner from below in the direction of the arrow-. Secure the belt tensioner with the locking pin -T10060 A-. Remove the poly V-belt from the vibration damper pulley.



Turn the torsional vibration damper with the stop "T10355" to the "TDC" position "arrow". The notch on the damper should be opposite the arrow mark on the lower cover of the chain drives.

Caution: Risk of engine defects. To avoid adjusting the valve timing, do not turn the crankshaft past TDC with the vibration damper bolt removed.

Unscrew the vibration damper bolt, use the "T10355" stop for this. Remove the vibration damper.

Caution: To avoid damaging the gear engagement, screw in the vibration damper bolt only using the "T10368" sleeve.

Screw in the vibration damper bolt and the "T10368" bushing again. Remove the engine casing. Remove the air filter.

Caution: Risk of damage to electronic components when disconnecting the battery. Observe measures for disconnecting the battery.

Disconnect the ground wire "arrow" from the battery with the ignition off. Remove the battery. Remove the battery bracket "arrow".

With automatic transmission

Screw the eye bolt "3368" into the gearbox as shown in the figure.



Install the crossbar -10-222 A- with the following components: adapter -10-222 A /22- (2 pcs.), adapter -10-222 A /3- (2 pcs.), hook -10-222 A /10- (2 pcs.), shackle -10-222 A /12-.

With manual transmission

Remove the gearshift mechanism. Install the crossmember -10 - 222 A- with the following components: adapter -10-222 A /22- (2 pcs.), adapter -10-222 A /3- (2 pcs.), hook -10-222 A /10- (2 pcs.), clevis -10-222 A /12-.

All

Create pre-tension on the engine using the spindle. Unscrew the "arrow" bolts of the power unit support on the engine. Remove the engine mount. Raise the engine by about 50 mm and unscrew the upper bolt of the engine support. Now lower the engine by about 100 mm.



Release the electrical wiring harness "arrow". Unscrew bolt "1" and remove the poly V-belt tensioner from the auxiliary unit bracket. Unscrew the lower engine mount bolts using chisel "T10099". Remove the engine mount with bolts.



Unscrew the "arrow" screws, remove the dipstick guide tube from the chain drive cover.



Unscrew the electromagnetic valve of the boost pressure limitation "N75" from the turbocharger "arrows". Remove the turbocharger nipple "1".



Remove screws -1...15-.

Caution: Risk of damage to the lower cover of the drive shaft. To avoid deformation, do not handle it by the areas between the screw connections.

Press down the lower cover of the chain drive, starting from points -1 and 2-.

Installation

Sealant: silicone sealant -D 174 003 AE-.

Instructions: Pay attention to the expiration date of the silicone sealant. The lid must be installed within 5 minutes after applying the silicone sealant. Replace the bolts that are tightened with additional tightening. Replace the sealing rings, gaskets and self-locking nuts.

Remove any remaining sealant from the cylinder block with a flat scraper. To prevent contamination from getting into the shaft seal, cover it with adhesive tape on both sides. Remove any remaining sealant from the cover using, for example, a hand drill with a rotating attachment - a polymer brush. Clean the mounting surfaces; there should be no oil or grease on them. Install the cover with the old bolts and tighten them to 8 Nm. Check the gap between the cover and the body using a feeler gauge; it should be no more than 0.2 mm.

Instructions: If this distance is more than 0.2 mm, replace the cover. Do not measure the distance between the cover at the top of the oil pan, but conduct a visual inspection for evenness of the seating surface.

Check that both dowel pins are present to center the "arrow" cover.



Cut off the tube tip along the front mark (hole diameter about 3mm). Apply silicone sealant -D174 003 AZ- to the clean seating surface of the cover. Thickness of the sealant bead: 2...3 mm,

Instructions: The cover must be installed within 5 minutes after applying the silicone sealant. The sealant bead must not be thicker than the prescribed value, otherwise, excess sealant may fall into the oil pan and clog the mesh filter in the oil intake pipe.

Install the cover and all bolts immediately. Tighten bolts -1...15- in 2 stages in the sequence shown.

• 1. Tighten the bolts to 8 Nm.
• 2. Tighten the bolts by 45°.

Instructions: After installing the cover, wait about 30 minutes for the sealant to dry. Only then can you fill in the engine oil.

Fill with engine oil. Check the oil level. Further installation is carried out in the reverse order.
