ABS AUDI TT 1996 8N / 1.G AEB ATW Engines Charge Air System With Turbocharger Workshop Manual

21-56


Notes: - Turn turbocharger tester on and select measuring range -I- (absolute
pressure).
- Connect test hose to connection barb -I-.
Hoses must be properly connected and there must be no possibility of
leaks, otherwise incorrect readings may result. Make sure that the test hose is not pinched at the hood or at the side
window. By pressing memory button "M" on turbocharger tester, the last test
value is saved until either memory button "M" is pressed again or the
turbocharger tester is shut-off. A blinking comma in the display field indicates that a value has been
saved. An arrow appears in the top left corner of the display field if the
turbocharger tester battery voltage drops below the permitted
threshold. Before testing, drive vehicle rapidly for at least 3 km on a road that
does not require stopping (i.e. traffic lights or similar). A second technician is required because the indicated values must be
read out while the vehicle is being driven.
