WARNING:
Observe warning on cylinder head cover.
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 40°C.

WARNING:
Wear full face guard and protective gloves.
Fuel can emerge spontaneously at high velocity from the fuel injectors!
To reduce the fuel pressure, place rag over fuel injector and carefully tap against the fuel injector with a spanner.
There is a risk of injury if the fuel pressure is not reduced!

IMPORTANT:
When assembling, it is essential to adhere to screwing sequences and tightening torques!
Failure to comply with this requirement may result in leaks!
Failure to comply with this requirement may result in leaks!
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.
- High-pressure lines may be rescrewed a maximum of 10 times.
IMPORTANT:
Injectors are not waterproof!
Carry out engine cleaning/washing only with ignition coil cover fitted.
Carry out engine cleaning/washing only with ignition coil cover fitted.
Necessary preliminary tasks:
- Remove IGNITION COIL of corresponding cylinder
NOTE:
- 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! Cloths/rags must therefore be used to prevent fuel from getting into the spark plug slots!
- Before installing ignition coils, clean spark plug slots with compressed air.
- Make sure the spark plug slot is absolutely clean.
- Remove PRESSURE LINE of corresponding cylinder
NOTE:
The following description applies to all injectors.
Unlock plug (1) and remove.
Release screw and remove holding-down element (2).
Remove injector (3).
NOTE:
If several injectors are removed, ensure that each injector is reinstalled in its original location (cylinder).
Mark injectors.
