filler neck.
Screw in rear towing eye and hook special tool 16 1 150 into it.
Connect special tool to workshop compressed air system (8 - 10
bar) with compressed air hose (1).
Connect pressure sensor (Diagnosis and Information System) with
measuring range of 0-3.5 bar.
Caution!
Make sure that the pressure regulator on special tool
16 1 150 is set completely in the "-" direction and the non-
return cock between the pressure regulator and the pressure
sensor is closed.
Select the "Measuring Technology" function on the Diagnosis and
Information System (DIS). Set the measuring range in accordance
with the pressure sensor to 0-3.5 bar.
Open the non-return cock on special tool 16 1 150 and increase
the pressure in the tank system by 0.050 bar with the pressure
regulator.
Caution!
Never increase the pressure by more than 0.100 bar, as
otherwise damage to the fuel tank and tank ventilation system
is possible.
Close non-return cock.
Wait for approx. 20 secs. for system to settle, read off pressure
value then wait for 60 secs.
Read off final pressure value and compare with starting pressure
value. If the pressure drop is in the area between 0.008 and 0.12
bar, the measurement must be repeated to obtain a confirming
result.
If the pressure drop in 60 sec. is greater than 0.010 bar, the
system is impermissibly leaky.
Carry out leak test,
