The engine with transmission is removed downward.
-- Check the Diagnostic Trouble Code (DTC) memories for all the control modules. Refer to the vehicle diagnostic tester.
All cable ties which are opened or cut off when removing the engine, must be replaced in the same position when installing the engine.
Leave the key in the ignition lock to prevent the steering lock from engaging.
It is advisable to remove the front wheels before removing the engine/transmission assembly. The vehicle can be lowered on the hoist until the cover plates for the brake discs are just above the floor. This enables the most ergonomic work position regarding accessibility of components in the engine compartment.
When the engine is installed in the engine compartment some components cannot be removed or can only be removed with great difficulty. Therefore determine which components are faulty before removing the engine.
To prevent damage to the removed components, use the parts trolley V.A.G 1698 for storage.
When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:
- Route all lines and wires in their original locations.
- Make sure the wires have enough clearance to all moving or hot components.
Turn off the ignition and disconnect the ground cable from the battery. Refer to Removal and Installation .
-- Completely remove the air filter housing with the connecting hose to the throttle valve control module -J338-. Refer to AIR FILTER HOUSING OVERVIEW .

-- Disconnect the oxygen sensor connectors -1 through 4- at the bulkhead and free up the wires:
1 - Heated Oxygen Sensor (HO2S) -G39-, 6 pin harness connector (black)
2 - Oxygen Sensor (O2S) after Three Way Catalytic Converter (TWC) -G130-, 4 pin harness connector (black)
3 - Heated Oxygen Sensor (HO2S) 2 -G108-, 6 pin harness connector (brown)
4 - Oxygen Sensor (O2S) 2 after Three Way Catalytic Converter (TWC) -G131-, 4 pin harness connector (brown)
On vehicles with All Wheel Drive (AWD), the connectors for the O2S after TWC -2- and the O2S 2 after TWC -4- are secured to the underbody.
-- Disconnect all connectors from the transmission.
-- Remove all remaining electrical wires necessary from the engine/transmission and set aside.
-- Disconnect the selector lever cable -1- from the selector shaft. Then pull the selector lever cable out of the bracket -2-.
The fuel supply line is under pressure! Wear protective goggles and protective clothing to prevent injuries and contact with skin. Before disconnecting, wrap a cloth around the connection. Then release pressure by carefully the loosening union nut.
-- Disconnect the ventilation line -1-, the vacuum line -2- and the fuel supply line -3-. Press the release buttons to do this.
-- Disconnect the vacuum line from the brake booster.
-- Disconnect all other vacuum and intake hose connections from the engine.
-- Seal the lines so that the fuel system is not contaminated by dirt, etc.
-- Observe the rules for cleanliness. Refer to CLEAN WORKING CONDITIONS .
Hot steam may escape when opening the expansion tank. Wear protective goggles and protective clothing to prevent damage to eyes and scalding. Cover the cap with a cloth and open very carefully.
-- Open and close the cap on the expansion tank, to relieve the cooling system pressure.
-- Remove the fan shroud and fans. Refer to FAN SHROUD WITH FANS .
-- Remove the lower sections of the front wheel housing liners. Refer to Removal and Installation .
-- Disconnect the connector from the oil level thermal sensor -G266-.
-- Remove the wire bracket for the oil level thermal sensor from the subframe.
To prevent damage to the Air Conditioning (A/C) condenser and the refrigerant lines and hoses, do not stretch, kink or bend the lines and hoses.
In order to remove and install the engine without opening the refrigerant circuit:
-- Remove the ribbed belt. Refer to RIBBED BELT .
-- Unbolt the A/C compressor from the accessory bracket. Refer to Removal and Installation .
-- Secure the A/C compressor to the lock carrier so that the refrigerant lines/hoses are not burdened.
-- Remove the drive axle heat shield for the right drive axle.
-- Remove the drive axles. Refer to Removal and Installation .
Vehicles with All Wheel Drive (AWD):
-- Unbolt the driveshaft front flexible disc from the transmission. Refer to the appropriate service information .
Continuation for All Vehicles:
-- Remove the front exhaust pipes with catalytic converters, refer to one of the following:
AWD, refer to FRONT EXHAUST PIPES WITH CATALYTIC CONVERTERS AND FRONT MUFFLERS .
Front Wheel Drive (FWD), refer to FRONT EXHAUST PIPES WITH CATALYTIC CONVERTERS AND FRONT MUFFLERS .
Do not bend the decoupling elements of the exhaust pipes more than 20° or they could be damaged. Two technicians are needed to perform the removing procedure.
-- Remove the bolts -1 through 3- and remove the pendulum support.
-- Drain the coolant. Refer to DRAINING AND FILLING .
