Checking with engine leak detector spray G 001 800 A1

Special tools, testers, measuring instruments and auxiliary items required

• ◆ Fault reader V.A.G 1551 or vehicle system tester V.A.G 1552 with cable V.A.G 1551/3
• ◆ Engine leak detector spray G 001 800 A1

Notes:

• ◆ The vacuum in the intake system will cause the leak detector spray to be drawn in with the outside air. The leak detector spray reduces the ignitability of the mixture. This leads to a drop in engine speed and to a significant increase of the CO content.
• ◆ The safety precautions listed on the container must be adhered to.

Test conditions
