On-Vehicle Inspection [03/2019 - ]: Procedure
- DISCHARGE FUEL SYSTEM PRESSURE WARNING:
- Make sure the engine coolant temperature is 60°C (140°F) or less when performing this procedure.
- Do not disconnect any part of the fuel system until you have discharged the fuel system pressure.
- Pressure will still remain in the fuel lines even after performing the following procedure. When disconnecting a fuel line, cover it with a piece of cloth to prevent fuel from spraying or coming out.
- Remove the deck side trim cover RH.
- Remove the fuse from the position shown in the illustration.
- Start the engine. After the engine has stopped on its own, turn the ignition switch off.NOTE:
Do not increase the engine speed or drive the vehicle while waiting for the engine to stop on its own.
- Crank the engine again and make sure that the engine does not start.
HINT:
Clear the fault code before proceeding to the next step.
- Remove the fuel tank cap and discharge the pressure from the fuel tank assembly.
- Disconnect the cable from the negative (-) battery terminal.
- Install the fuse.
- Install the deck side trim cover RH.
- CHECK FUEL DELIVERY PRESSURE WARNING:
- Working on fuel system.
- Risk of fire! Danger of explosion!
- When working on the fuel system, make sure that the workbay is sufficiently ventilated, e.g. using extraction unit.
- Tightly seal off open lines and connections; collect any escaping fuel directly at the point of exit.
- No fire, sparks, open flames or smoking.
- On releasing high pressure line, fuel may emerge at high speed.
- Danger of injury!
- Wear suitable personal protective equipment.
- Allow the cooling system to cool down to a temperature below 40°C before starting installation work.
- Note warnings on cylinder head cover.
HINT:
Collect and dispose of emerging fluids. Observe country-specific waste disposal regulations.
- Detach the circlip (1).
- Unlock lock (2).
- Detach the fuel hose (3) from fuel line.
- Catch and dispose of escaping fuel.
- Unscrew adapter (1) of the special tool 0 491 310 (13 5 270).
- SST: 09200-WA020
- In the separate fuel supply line the special tool0 491 310 (13 5 270).
- SST: 09200-WA020
- Fuel pressure gauge on the Screw special tool 0 491 310 (13 5 270).
- SST: 09200-WA020
- Build up fuel supply pressure.
- Read off fuel pressure at the pressure gauge.
- Observe the diagnostic instructions.
- After completing the measurement: Remove all special tools.
- Collect and dispose of escaping fuel with suitable equipment.
- Connect the fuel hose to the fuel line and lock
- Collect and dispose of escaping fuel with suitable equipment.
- Atach the circlip.
