Check fuel delivery pressure
NOTE:
DANGER
High voltage.
Mortal hazard through electric shock!
High voltage.
Mortal hazard through electric shock!
- Before removal, disconnect all components from the voltage supply: Switch off lighting system and ignition.
- For additional information see:
63 99... SAFETY INSTRUCTIONS FOR HANDLING BULBS/LIGHT SOURCES (EXTERIOR LIGHTING)
WARNING:
Working on fuel system.
Risk of fire! Danger of explosion!
Risk of fire! Danger of explosion!
- When working on the fuel system, make sure the workstation has sufficient ventilation, e.g., by means of extraction.
- Tightly seal off open lines and connections; collect any leakage fuel directly at the point of exit.
- No fire, sparks, open flames or smoking.
CAUTION:
On releasing high pressure line, fuel may emerge at high speed.
Injury hazard!
Injury hazard!
- Wear suitable personal protective equipment.
- Before performing any installation work, allow cooling system to cool down to less than 40°C.
- Note warnings on cylinder head cover.

- Unlock and loosen clamp (1).
- Guide and remove cover (2) in arrow direction.
- Detach the circlip (1).
- Release lock (1) arrow direction.
- Release the fuel hose (2) from the fuel supply line (3).
- Catch and dispose of leakage fuel.
- Unscrew the adapter (1) from the special tool 0 491 310 (13 5 270).
Check
- Insert the special tool 0 491 310 (13 5 270) into the disconnected fuel supply line.
- Screw onto special tool 0 491 310 (13 5 270) , the special tool 0 496 623 (11 4 310).
- Screw 0 496 623 (11 4 310) the IMIB 100 bar pressure sensor (1) onto the special tool.
- Connect the IMIB 100 bar pressure sensor (1) to the Integrated Measurement Interface Box (IMIB).
- Establish fuel delivery pressure.
Result
» Read the fuel delivery pressure on the Integrated Measurement Interface Box (IMIB) and compare it with the values in the diagnostic system.
Measure
- Follow the instructions of the diagnostic system.
- After completing the measurement, disconnect and remove the special tool 0 491 310 (13 5 270) with the special tool 0 496 623 (11 4 310) and the IMIB-100-bar pressure sensor (1) from the fuel supply line.
- Catch and dispose of leakage fuel.
- Connect the fuel hose (2) to the fuel supply line (3) in the direction of the arrow and lock.
The lock (1) must audibly engage.
- Fasten the circlip (1).
- Slide the cover (1) in the direction of the arrow into the guide (2) and install it.
- Lock clamp (3).
The clamp (3) must engage audibly.
