Prepare charge air system tester -V.A.G 1687- as follows:
– Pull pressure control valve -2- upwards, unscrew it com‐
pletely, and close valves -3- and -4-.
– Connect charge air system tester -V.A.G 1687- to com‐
pressed air -1- via commercial adapter.
Note
♦ If there is water in the inspection glass -6-, drain it via the
drain plug.
♦ The test pressure must not exceed 0.2 bar. Otherwise there
is a risk of damage to the engine.
– Open valve -3-.
– Adjust pressure to 0.2 bar with pressure control valve -2-.
– Open valve -4- and wait until test circuit is full. If necessary,
adjust pressure to 0.2 bar.
– Check charge air system for leaks by listening, touching,
with commercially available leak detector spray or using ul‐
trasonic 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.
♦ Ultrasonic tester -V.A.G 1842- ⇒ operating instructions
♦ Before removing the adapters, depressurise the test circuit
by detaching the hose coupling.
