Checking intermediate shaft (9) and camshaft (10) backlash; adjusting if necessary — AUDI

🧭 Before you start

Fits: platform code 2DA

• Timing position: the crankshaft or camshaft is set and locked during this job
• Special tools named: dial gauge

Don't miss

• Before removing camshaft toothed belt pulley, use special wrench3447 to turn crankshaft to the TDC mark (arrow).
• To counterhold engine, position special wrench3447 on vibration damper bolts.
• Loosen bolt from adjustment bearing (arrow A) (do not remove).

🔩 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 maintenance aperture cover: 50
2. Remove cylinder head cover.
3. Remove rocker finger .
4. Before removing camshaft toothed belt pulley, use special wrench3447 to turn crankshaft to the TDC mark (arrow).
5. To counterhold engine, position special wrench3447 on vibration damper bolts.

6. Remove camshaft sprocket.
7. Secure dial gauge with universal dial gauge bracketVW 387 to cylinder head.
8. Determine backlash at intermediate shaft.
9. Position camshaft sprocket and tighten camshaft bolt hand-tight.
10. Now determine backlash by holding intermediate shaft and simultaneously turning (arrow) camshaft.
11. Unscrew sealing cap for intermediate shaft.
12. Loosen bolt from adjustment bearing (arrow A) (do not remove).
13. Backlash can be adjusted by moving bearing to the side (arrow).
14. After adjusting, tighten adjustment bearing bolt to 110 Nm. — 110 Nm (81 lb-ft)
15. Tighten sealing cap for intermediate shaft with new seal.
16. Lock camshaft at cylinder 4 using camshaft clamp3445.
17. Remove camshaft clamp3445.
18. To counterhold engine, position special wrench3447 on vibration damper bolts.
19. Tighten camshaft sprocket bolt to 180 Nm. — 180 Nm (133 lb-ft)
20. Remove special wrench3447.
21. Tighten vibration damper dust cap to 10 Nm. — 10 Nm (7.4 lb-ft)
22. Install rocker finger .
