t	10 mm articulated wrench -3185-

t	Socket and key -T10058-

t	Torque wrench -V.A.G 1331-

t	Flat scraper

t	Silicone sealant -D 176 404 A2-

Remove sump.

–	Remove the soundproofing → Bodywork, exterior installation work; Rep. gr.50.

–	Drain engine oil.

Note

Please observe requirements for disposal.

–	Unscrew the gearbox and oil sump fixing bolts.

–	Disconnect the connector from the oil level and temperature sender -G266-.

–	Loosen the oil sump bolts on the flywheel side of the engine with the articulated wrench e/c 10 -3185-, and remove them with the socket -T10058-.

–	Loosen the remaining bolts, and remove the oil sump. If necessary, release the oil sump by tapping it gently with a rubber hammer.

Installing sump:

Note

t	Observe use-by date of sealant.

t	The oil sump should be fitted into place 5 minutes after the application of the sealant.

–	Cut off tube nozzle at upper marking (nozzle Ø: approx. 3 mm).

–	Apply the silicone-based sealant to the clean contact surface of the oil sump, proceeding as shown. The strip of sealant must:

t	2...3 mm thick.

t	Apply along the inner edge of the bolt holes -arrows-.

Note

The sealant bead must not be thicker. Otherwise the excess sealant may enter the oil sump, and obstruct the strainer in the oil intake pipe.

–	In the area of the arrow, the sealant bead must be applied with special care.

–	Fit the oil sump immediately, and tighten the bolts as described below:

1 -	Tighten all the bolts of the oil sump/engine block slightly crosswise.

2 -	Tighten the bolts of the oil sump/gearbox slightly.

3 -	Retighten all the bolts of the oil sump/engine block slightly crosswise.

4 -	Tighten the bolts of the oil sump/gearbox bolts to 25 Nm.

5 -	Tighten all the bolts of the oil sump/engine block crosswise to 15 Nm.

Note

t	When installing sump with engine removed, ensure that sump is flush with crankcase at flywheel end.

t	Starting can be carried out 30 minutes after applying the sealant to the oil sump. Only then should the engine be refilled with oil.

Further assembly is basically the reverse of the dismantling sequence.
