🔧 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. Remove air filter .
2. ⚠ Fuel supply lines are under pressure! Wear eye protection and protective clothing to avoid possible injury and skin contact. Before loosening hose connections, wrap a cloth around the connection. Then release pressure by carefully pulling hose off connection. — Separate fuel supply line (arrow).
3. Pull connector and fuel supply line (arrows) off high-pressure pump. [Note: Catch escaping fuel in a cloth.]
4. Remove wiring guide (2) and take clip (4) off high-pressure line. [Note: Use a spanner to counterhold threaded connections on high pressure pump and on lower part of intake manifold when loosening union nuts.]
5. Loosen union nuts (1) and (3) of high-pressure line.

6. Remove securing bolts (1), (2) and (3) equally.
7. Pull high-pressure pump (3) and bucket tappet (1) out of camshaft housing. [Note: Moisten high-pressure pump bucket tappet with clean engine oil.The high-pressure pump O-ring must always be renewed.]
8. Push bucket tappet (1) into camshaft housing.
9. Insert new, lubricated O-ring (2) in groove of high-pressure pump (3).
10. Place high-pressure pump (3) onto camshaft housing.
11. Tighten securing bolts (1), (2) and (3) equally.
12. Tighten union nuts of high-pressure line (1) and (3) hand-tight.
13. Install wiring guide (2) and fit clip (4) on high-pressure line. [Note: Use a spanner to counterhold threaded connections on high-pressure pump and on lower part of intake manifold when tightening union nuts.]
14. Tighten union nut (1) of high-pressure line to 18 Nm. — 18 Nm (13 lb-ft)
15. Tighten union nut (3) of high-pressure line to 18 Nm. — 18 Nm (13 lb-ft)
16. Secure fuel supply line and connector (arrows) on high-pressure pump.
17. Reconnect fuel supply line (arrow).
18. Install air filter .
