Detaching — AUDI
Detaching on Audi: 5 steps, 3 torque figures. What to remove, what to tighten and to how many Nm, what to check after.
Workshop procedure for AUDI — the exact step sequence and torque figures, straight from real workshop data.
🧭 Before you start
Fits: Audi A8 D3 (4E, 2002–2010)
- Opens: refrigerant (A/C)
Don't miss
- The cap of the replacement evaporator for example is a suitable means of sealing the open connections at the evaporator and the lines (to prevent the ingress of dirt and moisture).
🔩 Torque settings
Values can differ between engine variants — check the code stamped on your block.
| Torque | Fastener / step |
|---|---|
| 20 Nm (15 lb-ft) | Screw out bolts (A |
| 25 Nm (18 lb-ft) | Screw out the hexagon socket-head bolt (A |
| 25 Nm (18 lb-ft) | Unscrew the bolts (A |
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
- Drain the refrigerant circuit: Air conditioner with refrigerant R134a
- Remove the brake master cylinder and brake servo. Brake system47
- Unfasten the refrigerant lines at the suspension strut dome by removing the bolt (A).
- Screw out the hexagon socket-head bolt (A) (tightening torque 25 Nm). — 25 Nm (18 lb-ft)
- Detach the refrigerant lines (B) and (C) from the evaporator and seal the open connections. [Note: The cap of the replacement evaporator for example is a suitable means of sealing the open connections at the evaporator and the lines (to prevent the ingress of dirt and moisture).]

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
