– Connect the pneumatic hose -1- (pneumatic support) at tester.
Note
If there is water in the transparent drain container, drain water via
the drain plug -6-.
– Open valve -3-.
– Set the pressure to 0.05 MPa (0.5 bar) with the pressure con‐
trol valve -2-.
Caution
The pressure must not be greater than 0.05 MPa (0.5 bar)! A
too high pressure can damage the engine.
– Open valve -4- and wait until the test circuit is filled. If neces‐
sary, re-adjust the pressure to 0.05 MPa (0.5 bar).
– Listen to, touch or use commercially available leak search
spray or the ultrasonic measuring device e. g. -V.A.G 1842- to
check the charge-air system with exhaust gas turbocharger for
leak points.
Note
Minor leaks are permissible on the suction side of the turbo‐
♦
charger, because the intake hoses are not designed for over‐
pressure.
A small amount of air escapes via the valves into the engine.
♦
For this reason no pressure test is possible.
Using the ultrasonic tester - V.A.G 1842- ⇒ Owner's Manual .

In case of a leak point, observe the instructions for charge air
