🧭 Before you start

Fits: Audi TT Mk2 (8J, 2006–2014)

Don't miss

• Renew circlip (A).

🔩 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. Use e.g. a small screwdriver or long-nose pliers to carefully remove circlip (A) (with vulcanised rubber disc ), taking particular care not to damage pulley.
2. Hold drive shaft (B) of air conditioner compressor using a standard hexagon socket wrench (commercially available) and turn drive plate (C) with pulley (D) in direction of arrow (E) (tightening torque: 35 Nm). — 35 Nm (26 lb-ft)
3. Detach drive plate (C).
4. Remove circlip (A).
5. Detach pulley (B). [Note: Renew circlip (A).]

6. Install pulley (B).
7. Ensure that circlip (A) is fitted correctly. Bevelled side (C) faces away from air conditioner compressor (flat side faces compressor).
8. Insert rubber elements (D) into pulley (B) as shown.
9. Before installing drive plate, coat rubber elements (D) slightly with lubricant (e.g. tyre fitting paste or soap solution).
10. Insert drive plate (C) in rubber elements (D) (refer to top illustration) until it makes contact with shaft of air conditioner compressor (B).
11. Screw drive plate (C) onto compressor shaft (B) by turning in direction of arrow (F).
12. Tighten drive plate (C) (via pulley (D)) to 35 Nm by turning in direction of arrow (F) with a commercially available strap wrench (with fabric strap); hold compressor shaft (B) in position with a standard hexagon socket wrench (commercially available). — 35 Nm (26 lb-ft)
13. Fit circlip (A) (with vulcanised rubber disc).
