– Connect the Turbo System Tester Kit - Adapter 10 -
VAG1687/10- with the Adapter - VAG1687/14- to the turbo‐
charger.
– Connect the Turbo System Tester Kit - VAG1687- to the
adapter.
Prepare the Turbo System Tester Kit - VAG1687- as follows:
– Pull the pressure regulating valve -2- upward and remove
completely, close the valves -3 and 4-.
– Connect the Turbo System Tester Kit - VAG1687- to com‐
pressed air -1- with a commercially available adapter piece.
Note
♦
If there is water in the viewing glass, it must be drained through
the drain plug -6-.
♦
Pressure must not exceed 0.5 bar (7.2 psi)!
– Open the valve -3-.
– Set the pressure to 0.5 bar (7.2 psi) using the pressure control
valve -2-.
– Open the valve -4- and wait until the test circuit is filled. Reg‐
ulate the pressure to 0.5 bar (7.2 psi) again if necessary.
– Listen, feel and use commercially available leak detection
spray or the Ultrasonic Tester - VAG1842S- to check the
charge air system for leaks.
Note
♦
A small quantity of air dissipates via valves in engine. A pres‐
sure retention test is not possible for this reason.
♦
Information on the Ultrasonic Tester - VAG1842S- . Refer to
the Operating Instructions.
♦
Release the pressure in the test circuit by pulling off the hose
coupling before removing the adapter.
