Intake Air system, leak testing<br />

Checking with engine leak detector spray G<br />

001 800 A1<br />

Note:<br />

The vacuum in the intake system will cause the<br />

leak detector spray to be drawn in with the<br />

unmetered air. The leak detector spray reduces<br />

the ignitability of the mixture. This leads to a<br />

drop in engine speed and to a change of<br />

Oxygen Sensor (O2S) reading.<br />

The safety precautions listed on the container<br />

must be adhered to.<br />

Special tools, materials and equipment<br />

Note:<br />

VAG 1551 Scan tool (or VAG 1552) with VAG<br />

1551/3 adapter cable<br />

All functions which could previously be performed<br />

with VAG 1551/1552 can also be performed with<br />

the VAS 5051.<br />

Engine leak detector spray G 001 800 A1<br />
