🔩 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. Detach electrical connector (2) from bracket and unplug. [Note: Disregard (item 1).]
2. Take electrical connectors (1, 3) out of bracket, unplug connectors and move electrical wiring clear.
3. Unplug electrical connector (2), unclip pressure differential sender G505 from bracket and move clear.
4. Remove bolt (3). [Note: Disregard (items 1, 2).]
5. Unscrew nuts (arrows) and detach particulate filter with front exhaust pipe.

6. Unbolt drive shaft (left and right) from gearbox flange shafts Running gear, axles, steering40Drive shaft; Removing and installing drive shaft.
7. Release hose clip (arrow) and detach coolant hose.
8. ⚠ Risk of irreparable damage to gearbox control unit (mechatronic unit) because of electrostatic discharge.Before unplugging or plugging in electrical connector, mechanic must discharge static electricity. To do so, touch vehicle earth, heater radiator, or lifting platform, with your hand.Do NOT touch connector contacts in gearbox connector with your hands. — Turn retainer catch anti-clockwise (arrow) and unplug electrical connector at gearbox.
9. Move clear electrical wiring harness at gearbox. [Note: Disregard (items 1, 2).] [Note: Place a cloth underneath to catch escaping ATF.]
