Check fuel delivery pressure
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.

NOTE:
Schematic diagram is for example purposes. Some parts may differ in certain details.
- Detach the circlip (1).
- Unlock lock (2).
- Detach the fuel hose (3) from fuel line.
- Catch and dispose of leakage fuel.
- Unscrew the adapter from the special tool 0 491 310 (13 5 270) (1).
Check
- Insert special tool 0 491 310 (13 5 270) into disconnected fuel 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 completion of 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 in a suitable container.
- Connect and lock the fuel hose (3) to the fuel line (2).
- Fit circlip (1).
