🧭 Before you start

Fits: VW Golf VII Variant (BA), VW Golf VII (5G, 2012–2020), VW Sharan II / SEAT Alhambra (7N, 2010–), VW Passat B8 (3G, 2014–)

• Renewed: gaskets, cover

Don't miss

• Observe use-by date of silicone sealant.The sump (top section) must be installed within 5 minutes after applying the silicone sealant.Renew bolts tightened with turning further angle.Renew gaskets, oil seals and self-locking nuts.
• Clean sealing surfaces. They must be oil and grease free.
• Danger of blocking lubrication system with excess sealant. Do not apply sealant bead thicker than specified.

🔩 Torque settings

Values can differ between engine variants — check the code stamped on your block.

ℹ️ Always cross-check the exact figure against your vehicle's factory manual before final tightening — a wrong torque can damage the engine. These values are extracted from workshop data and may not cover every variant or revision.

📋 Procedure

1. Remove sump (bottom section) .
2. Remove rear sealing flange .
3. Remove oil pump .
4. Disconnect electrical connector (1).
5. Unscrew bolts (arrows).

6. Unscrew bolts (1 through 14).
7. Lever off top section of sump on gearbox side first. When levering off, exercise caution to ensure the timing chain cover is not bent in the process. [Note: Observe use-by date of silicone sealant.The sump (top section) must be installed within 5 minutes after applying the silicone sealant.Renew bolts tightened with turning further angle.Renew gaskets, oil seals and self-locking nuts.]
8. Remove sealant residues from cylinder block with a flat scraper.
9. Remove sealant residues from sump (top section) using a rotating plastic brush, for example. [Note: Check timing chain cover for deformation. To do this, fit sump upper part first without sealant and check gap between cover and sump upper part. If deformation is evident and cover cannot be aligned, renew cover after top section of sump has been installed.]
10. Clean sealing surfaces. They must be oil and grease free.
11. Check oil passages in top section of sump and in crankcase for soiling.
12. Cut off nozzle of tube at front marking (diameter of nozzle approx. 2 mm). [Note: Danger of blocking lubrication system with excess sealant. Do not apply sealant bead thicker than specified.]
13. Apply silicone sealant onto clean sealing surface of top section of sump as illustrated (arrow).
14. Apply silicone sealant between cylinder block and lower timing chain cover, as shown in illustration (arrows). [Note: After applying the silicone sealant, the top part of the sump must be fitted within 5 minutes.The bead of sealant must not be thicker than specified, otherwise excess sealant can enter the sump and obstruct the strainer in the oil intake pipe.]
15. Fit sump upper part immediately, and tighten bolts (1 to 14) in the sequence shown.
16. Tighten bolts (1 to 14) to 8 Nm. — 8 Nm (5.9 lb-ft)
17. Turn bolts (1 and 2) 180° further.
18. Turn bolts (3 to 9) 45° further.
19. Turn bolt (10) 180° further.
20. Turn bolts (11 to 14) 90° further.
21. Screw in new bolts (arrows). Specified torque: 8 Nm + 45°. — 8 Nm (5.9 lb-ft) + 45°
22. Install rear sealing flange .
23. Install oil pump
24. Insert new baffle plate, and bolt it on.
25. Install bottom section of sump .
26. Replenish engine oil and check oil level Engine oil: Draining; Renewing oil filter and replenishing engine oil.
