Zero Position Sensor
The zero position of the swivel module with respect to the zero position
sensor is detected by a 1/0 edge when
swivelling from the direction of the off position in the direction of the
optical axis. The swivel module is
repeatedly calibrated during operation based on this "soft" reference point.
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.
