Oil Pan: Service and Repair

Oil Pan

Special tools, testers and auxiliary items required

• T Bar and Socket 10 mm (3185)

• Hex Ball Socket (T10058)

• Torque Wrench (5-50 Nm) (V.A.G 1331)

• Flat Scraper

• Silicone Sealant (D 176 404 A2)

Removing

- Remove the noise insulation.

- Drain the engine oil.

• Observe disposal regulations!

- Remove the charge air pipe bolts - arrows -.





- Remove the auxiliary coolant pump bolt - 1 - and charge air pipe bolt - 2 -.





- Remove the oil return line bolts - arrows -.





- Remove the transmission to oil pan bolts - arrows -.





- Loosen the oil pan bolts on the flywheel side using (3185) and remove them using (T10058).

- Remove the remaining bolts and remove the oil pan. Loosen the oil pan with light blows from a rubber mallet if necessary.

- Remove the sealant residue from the cylinder block with a flat scraper.

- Use a rotating plastic brush to remove any remaining sealant on the oil pan.





Installing

• Note the expiration date of the sealant.

• The oil pan must be installed and the bolts tightened immediately after application of the sealant.

- Cut the tube nozzle at the front mark (nozzle diameter approximately 3 mm).





- Apply the sealant to the clean sealing surfaces of the oil pan as shown. The sealant bead must be:

• 2 to 3 mm thick

• and run on the inside of the bolt holes - arrows -

• Sealant bead must not be thicker than specified. Otherwise, excess sealant could get into the oil pan and clog the strainer in the oil intake pipe.

• With the transmission removed, the oil pan must seat flush with the cylinder block.

• With the transmission installed, the oil pan must make contact with the transmission.

• After installing the oil pan, allow the sealant to dry for approximately 30 minutes. Only after then may the engine oil be added.

- Immediately position the oil pan and tighten the bolts as follows:

1 Tighten the oil pan to cylinder block bolts very lightly in a diagonal sequence.
2 Tighten the oil pan to transmission lightly.
3 Tighten the oil pan to cylinder block bolt again lightly in a diagonal sequence.
4 Tighten the oil pan to transmission bolts to 40 Nm.
5 Tighten the oil pan to cylinder block bolts in a diagonal sequence to 15 Nm.

The rest of the installation is basically a reverse of the removal sequence.
