- Remove cover .
- ⚠ 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. — To pull off delivery line (1), first push delivery line onto delivery module (2) as far as stop.
- Then press securing clips of delivery line (arrow) together and pull delivery line off delivery module.

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.
