Prepare tester for charge air system - V.A.G 1687- as follows:
– Unscrew pressure control valve -2- fully and close the valves
-3- and -4-.
• The rotary knob must be pulled to the top in order to rotate the
pressure control valve -2-.
– Connect tester for charge air systems - V.A.G 1687- to com‐
pressed air using a commercially available intermediate piece
-1-.
Note
If there is water in the inspection glass, drain water via the drain
plug -6-.
– Open valve -3-.
Caution
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).
– To check the charge air system for leak points, listen, touch or
use commercially available leak search spray or the ultrasonic
measuring device - V.A.G 1842- .
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
