Removing and installing brake fluid reservoir, hybrid vehicles on VW: 13 steps. What to remove, in what order, and what to check after.
Workshop procedure for VW — the exact step sequence and torque figures, straight from real workshop data.
🧭 Before you start
Fits: VW Jetta VI (16, 2010–2018); platform code AV2
- Opens: brake fluid
Don't miss
- Ensure that seals are correctly seated in brake master cylinder.
- Brake fluid must not be filled above MAX marking (1) to prevent brake fluid from running out.
📋 Procedure

- Pull air damper (1) upwards out of rubber bushes (arrows).
- Place sufficient lint-free cloths in area of engine and gearbox.
- Draw off as much brake fluid as possible from brake fluid reservoir using brake filling and bleeding equipmentVAS 5234.
- ⚠ Never allow brake fluid to come into contact with fluids that contain mineral oils (e.g. oil, petrol, cleaning agents). Mineral oils damage the plugs and seals in the brake system.Brake fluid is poisonous and must never be sucked out by mouth through a hose. Because of its caustic properties, it must also not come into contact with paintwork.Do not reuse drawn-off brake fluid.Always observe the relevant environmental regulations for disposal. — Release connector (1) and pull it off brake fluid level warning contact F34.

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.
