- To pull off delivery line, first push delivery line onto delivery module as far as stop.Then push securing clips of delivery line (arrow) together and pull delivery line off delivery module.Cut through any cable ties.
📋 Procedure
- ⚠ The reducing agent can irritate skin, eyes and respiratory organs.After skin contact with this agent, wash immediately with plenty of water.If necessary seek advice from a doctor. — Emptying tank for reducing agent .
- ⚠ Immediately seal all openings and connections using suitable plugs to stop ingress of dirt. The smallest particle of dirt can cause extensive damage to the system.Protect separated electrical connections against wetting from reducing agent by suitable means, e.g. plastic bag and cable ties. Electrical connections may be damaged due to the high penetration ability along with subsequent crystallisation of the reducing agent. — Remove connectors of delivery module (1) from their holder and disconnect connectors.
- Unclip wiring harness and delivery line from body (arrows).
- Unfasten screw-type clip (3) and pull connecting hose (2) off reducing agent tank.
- Place engine and gearbox jackV.A.G 1383 A under reducing agent tank.
- Unscrew securing bolts of tensioning straps (1).
- Lower reducing agent tank until vent pipe and delivery line can be pulled off. [Note: To pull off delivery line, first push delivery line onto delivery module as far as stop.Then push securing clips of delivery line (arrow) together and pull delivery line off delivery module.Cut through any cable ties.] [Note: Make sure that all components are attached to reducing agent tank and that lines are routed as shown.]
- Carefully lift reducing agent tank using engine and gearbox jackV.A.G 1383 A until securing bolts of tensioning straps can be positioned.
- Tighten securing bolts.
- Connect electric cables.
- Clip wiring harness and delivery line to body.
- Fill reducing agent tank 10.2.

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.
