🔩 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.

10. Move electrical wiring clear. [Note: Disregard (item 1).]
11. Unscrew bolts (1) and (2) and detach heat shield for turbocharger.
12. Unscrew nuts (arrows) and remove starter catalytic converter with particulate filter.
13. Move coolant hoses clear (arrow).
14. Release hose clip (2), lift retaining clip (4) and detach coolant hoses.
15. Move clear breather hose (arrow) for gearbox.
16. Remove bolts (1) and (3) and detach coolant pipe (left-side) at rear of gearbox.
17. Remove bolts (arrows) securing front propshaft to transfer box Transfer box 0BU, front final drive 0BM, 0C1 and rear final drive 0BN, 0BP39. [Note: Lay a cloth under the separating point to catch escaping ATF.Observe rules for cleanliness when working on automatic gearbox 00.]
18. Remove bolts (1) and (2) and detach ATF lines from gearbox.
19. Remove bolt (arrow) and detach ATF lines.
20. Remove alternator (1)Electrical system27.
21. Remove starter Electrical system27.
22. Insert guide pin of adapter T40058 as follows:
23. Counterhold crankshaft using adapter T40058 when slackening bolts for torque converter.
24. ⚠ Irreparable damage can be caused if the camshaft timing chains slip.When performing the next step, turn the crankshaft only in the normal direction of rotation (arrow). — Detach cover (arrow).
25. Remove 6 bolts (arrows) for torque converter through opening for starter (turn crankshaft 120° in direction of engine rotation each time).
26. Remove bolts (3 ... 10) securing gearbox to engine.
27. Loosen clamping bolts (1) on sides of scissor-type assembly platformVAS 6131 A and pull rear section of platform together with gearbox slightly towards rear.
28. Reach through aperture for removed starter motor and press torque converter off drive plate.
29. Secure the torque converter in the gearbox using support bridge30 - 211 A to prevent it falling out.
