BMW 7 Series: Replacing Low-Pressure Fuel Sensor (N63)
WARNING: Disconnect BATTERY NEGATIVE TERMINAL (risk of fire due to short-circuiting on removal).
Electric fuel pump starts up automatically when door is opened! Carry out installation work on fuel system only with coolant temperature below 40ºC.
Wear protective goggles.
IMPORTANT: Adhere to conditions of absolute cleanliness when working on the high-pressure fuel system.
Introduced contaminants can cause malfunctions in the system!
- Do not allow any dirt particles or foreign bodies to get into the system.
- Remove all traces of dirt before removing pipes or individual components.
- Use only fluff-free cloths.
- Seal all fuel system openings with protective caps or plugs.
IMPORTANT: Ignition coils must not be fouled by fuel.
The resistance of the silicone material is reduced significantly by contact with fuel, which may cause the ignition coil to fail! Cover ignition coil with suitable means.
Necessary preliminary tasks
- Remove left intake duct.
Recycling
Catch and dispose of escaping fuel in a suitable container.
Observe country-specific waste-disposal regulations.
Unlock plug (1) and remove.
