🔧 Engine codes this applies to

🔩 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. ⚠ Make sure the vehicle cannot tip over when the engine is removed.Secure the vehicle, to do so, the luggage compartment must be empty.The fuel system operates at extremely high pressure. This can cause injury.The fuel pressure in the high-pressure section of the injection system must be reduced to a residual pressure prior to opening the system. — Set front wheels to straight-ahead position.
