Tightening torque: 65 Nm
Remove starter from the front of vehicle.

Note:

To avoid having to check and adjust wheel alignment, only loosen the front subframe mountings and lower the subframe at the front.

Remove lower section of sump.
Detach return pipes for turbocharger from upper section of sump.

Unbolt cover plate -2- for oil pump sprocket.

Notes:

When loosening bolt -2- securing cover plate, counter-hold at welded nut.
When installing, make sure that the plate engages in position -arrows-.

Unbolt oil pump from engine so that the shorter oil supply pipe can be detached (do not remove oil pump).
Unscrew bolts securing upper section of sump to gearbox.
Unbolt upper section of sump from engine.

Note:

Two M6 bolts and two M8 bolts are located vertically at rear of sump upper section (in front of joint between engine and gearbox).

Installing:

Install in the opposite order to removing. When installing, note the following points:

Clean the sealing surfaces; ensure that they are free of oil and grease.

Warning
Wear protective goggles.
Remove any residues of sealant on sump and engine block using plastic brush attachment, or similar.

Note:

The sump must be installed within 5 minutes after applying silicone sealant.

Sealant

=> Parts Catalogue

Cut off nozzle of tube at front marking (diameter of nozzle approx. 3 mm).
Thickness of sealant bead: 2 ... 3 mm

Note:

The bead of sealant must not be thicker than 3 mm, as otherwise excess sealant may enter the sump and block the strainer in the oil intake pipe.

Make sure sealing surface is clean and then apply silicone sealant on sealing surface of sump, as shown in illustration. (Illustration shows position of sealant on cylinder block.)

Note:

Be particularly careful when applying the sealant around the rear sealing flange -arrows in illustration-.

Locate sump in position immediately, and tighten all bolts securing sump to cylinder block to 5 Nm initially.
Tighten bolts securing sump to gearbox to 45 Nm.
Tighten bolts securing sump to cylinder block in diagonal sequence in 2 stages; tighten to 10 Nm when tightening second time.
Tighten M10 bolts securing sump to cylinder block to 45 Nm.

Clean both sealing surfaces for lower section of sump; ensure that they are free of oil and grease.
Fit new gasket on lower section of sump and install on upper section of sump with two diagonally opposite bolts.
Tighten all securing bolts hand-tight.
Tighten bolts to 10 Nm with torque wrench, working from the centre outwards.
Fit new seal on oil drain plug and tighten to 30 Nm.

Notes:

When installing the upper section of the sump with the engine removed from the vehicle, ensure that the sump is positioned flush with the cylinder block at the flywheel end.
The sealant must be left to dry for about 30 minutes after installing the sump before engine oil can be put in.

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
