– Unscrew pressure relief valve-2- completely, close valves -3-
and -4-.
Note
The rotary knob must be slightly pulled to the top in order to rotate
the pressure control valve -2-.
– Connect testing device for charge-air systems - V.A.G 1687-
to the compressed air -1- using a commercially available
intermediate piece.
Note
If there is water in the inspection glass, drain water via the drain
plug -6-.
– Open valve -3-.
WARNING
Risk of damage owing to pressure being set too high.
♦ The pressure must not be greater than 0.05 MPa (0.5 bar)!
– Set the pressure to 0.05 MPa (0.5 bar) with the pressure con‐
trol valve -2-.
– Open valve -4- and wait until the test circuit is filled. If neces‐
sary regulate the pressure to 0.05 MPa (0.5 bar).
– Listen to, touch or use commercially available leak search
spray or the ultrasonic measuring device - V.A.G 1842- to
check the charge-air system for leak points.
Note
A small amount of air escapes via the valves into the engine.
♦
For this reason no pressure test is possible.
Use of ultrasonic measuring device - V.A.G 1842- ⇒ operating
♦
instructions .
Before removing the adapter, depressurize the test circuit by
