Oil pan, removing and installing
Special tools and equipment
^ VAG 1331 Torque wrench (5 50 Nm)
^ D 176 404 A2 Silicone sealing compound
^ Hand drill with plastic brush attachment
^ Flat scraper
^ Protective goggles

Removing
- Remove center, left and right insulation trays
- Unscrew bracket for secondary air pump motor -V101- from oil pan and from cylinder block.
- Drain engine oil.

Note: Observe waste disposal regulations!

- Remove oil pan.
- If necessary loosen oil pan with light blows of a rubber mallet.
- Remove sealant residue from cylinder block with a flat scraper.





- Remove sealant residue from pan with a rotating brush, e.g. a hand drill with a plastic brush attachment (wear protective goggles).
- Clean sealing surfaces. They must be free of oil and grease.

Installing

Note:
^ Note the expiration date of the sealing compound.
^ Oil pan must be installed within 5 minutes of applying silicone sealing compound.





- Cut off tube nozzle at front marking (nozzle approximately 3 mm diameter).
- Apply silicone sealing compound, as shown, to clean oil pan sealing surface. Sealing compound bead must be:
^ 2...3 mm thick,
^ and run on inside of bolt holes -arrows-.

Note: The sealing compound bead must not be thicker, otherwise excess sealing compound will enter the oil pan and may block the oil suction pipe strainer.





- Apply silicone sealing compound bead as illustrated to clean sealing surface of oil pan.
- Install oil pan immediately and tighten all pan bolts lightly.
- Tighten oil pan bolts to 12 Nm.
- Tighten bolts for pan/transmission to 45 Nm.
- Tighten bracket for secondary air pump motor:
Securing bolts to oil pan: 8 Nm
Securing bolts to cylinder block: 20 Nm

Note:
The sealing compound must be allowed to cure for approximately 30 minutes after installing the oil pan. After this time the engine may be filled with engine oil.
The rest of the assembly is basically in reverse order to the disassembling sequence.
