– Connect charge air system tester -V.A.G 1687- to compressed
air -1- via commercial adapter.
Note
If there is water in inspection glass, drain via drain screw -6-.
– Open valve -3-.
Caution
Risk of damage because pressure is set too high.
♦ The pressure must not exceed 0.5 bar!
– Adjust pressure to 0.5 bar with pressure control valve -2-.
– Open valve -4- and wait until test circuit is full. If necessary,
readjust pressure to 0.5 bar.
– Check charge air system for leaks by hearing, touching, with
commercially available leak detector spray or using ultrasonic
tester -V.A.G 1842- .
Note
♦
A small amount of air escapes through the valves and enters
the engine. Therefore a holding pressure test is not possible.
♦
How to use the ultrasonic tester -V.A.G 1842- ⇒ operating
instructions
♦
Before removing the adapters, depressurise the test circuit by
detaching coupling.
♦
Hose unions and air pipes/hoses must be free of oil and grease
when installing.
♦
Secure all hose connections with hose clips corresponding to
the series equipment ⇒ Electronic parts catalogue .
♦
In order to be able to securely attach the air ducts on their
connections, the screws of the used hose clips have to be
sprayed with penetrating spray before installing.
