CHECKING FILLER CAP PRESSURE RELIEF VALVE

Special tools required:

Set pressure regulator on special tool 16 1 171. See 16 1 170 TESTER WITH TEST ADAPTER fully in "-" direction.

Connect special tool 16 1 171. See 16 1 170 TESTER WITH TEST ADAPTER via compressed air line (1) to workshop/garage compressed air system (8... 10 bar).

Select special tool 16 1 172 or 16 1 173.

Install filler cap on selected special tool (3).

NOTE: Only the absolute pressure is indicated in the display of the Diagnosis and Information System (DIS). The current ambient air pressure is already displayed without additional pressurization.

Check testing equipment for leaks!

Select "Measurement" function on Diagnosis and Information System (DIS).

Set measuring range according to pressure sensor to 0-3.5 bar.

Increase pressure by 0.2 bar with pressure regulator on special tool 16 1 171.

Using special tool 13 3 010.

Wait 60 secs.

Read off final pressure value and compare with starting pressure value.

Measurement Evaluation:
