BMW 7 Series: Check Fuel Pressure
Necessary preliminary work:
Connect BMW diagnosis system.
IMPORTANT: Lines are under pressure!
Wear protective goggles and gloves.
Fuel can emerge spontaneously at high velocity when the fuel line is released!
Recycling:
Catch and dispose of escaping fuel with auxiliary materials.
Observe country-specific waste disposal regulations.
Check fuel delivery pressure:
To check the fuel delivery pressure, special tool 13 0 290 must be assembled as follows.
Screw adapter 11 4 310 onto line 13 0 291 (line). Screw the IMIB 100 bar pressure sensor (1) onto adapter 11 4 310.
Alternatively, the pressure gauge from the set of special tools 13 3 060 can be screwed onto line 13 0 291 (line).
Between lines 13 0 291 (line) and 13 0 292 (line), mount a shutoff tap (2) and a T-piece (3) from the set of special tools 13 3 060.
Close up T-piece (3) from the set of special tools with the cap 13 0 293 (fastener).

And Adapters
NOTE: The graphic shows F07.
The procedure is identical for other vehicles.
Remove circlip (1).
Unlock and detach fuel line (2) to fuel tank from fuel line (2) to high pressure pump.

Fig. 4: Identifying Circlip, Fuel Line And Fuel Tank
Install special tool (1) 13 0 290 into detached fuel line with IMIB fuel pressure sensor (100 bar).
Connect IMIB with fuel pressure sensor.
Establish fuel delivery pressure. Read off fuel delivery pressure on IMIB and compare with values in diagnosis system.

Check fuel holding pressure:
To check the fuel holding pressure, special tool 13 0 290 must be assembled as follows.
Screw adapter 11 4 310 onto line 13 0 291 (line). Screw the IMIB 100 bar pressure sensor (1) onto adapter 11 4 310.
Alternatively, the pressure gauge from the set of special tools 13 3 060 can be screwed onto line 13 0 291.
Between lines 13 0 291 (line) and 13 0 292 (line), mount a shutoff tap (2) and a T-piece (3) from the set of special tools 13 3 060.
Mount pressure gauge (4) from special tool set 13 3 060 onto T-piece (3) from special tool set 13 3 060.

Fig. 7: Identifying Circlip, Fuel Line And Fuel Tank
Install special tool (1) 13 0 290 with pressure gauge (2) and IMIB 100 bar fuel pressure sensor (3) into the detached fuel line.
Establish fuel delivery pressure.
Close shutoff tap (4) and switch off the engine.
Read off fuel holding pressure of high pressure pump from IMIB tester and compare with values in diagnosis system.
Read off fuel holding pressure to fuel tank on pressure gauge (2) and compare with values in diagnosis system.

Notes Regarding The Fuel Pressure Test (Reference Pressure:
Surrounding Area)
The characteristic of this version with ambient pressure:
The connection for the vacuum hose of the fuel pressure regulator is located
between the throttle and the air
cleaner or on the air cleaner.

Repairing Airbag Cables
IMPORTANT: Only repair those cables which show visible signs of damage. In
the event of
visible damage, make sure there is only one cable repair in effect after the
repair work. If no visible damage can be identified, the entire cable must be
replaced. When carrying out repairs to the airbag wiring
System Components
Park Distance Control
The Park Distance Control of the F01/F02 is identifiable by the five
ultrasonic sensors on the front bumper. The
fifth sensor enables a high level of reliability in obstacle recognition to be
achieved despite the large front end
of the F01.
