Air Leak Checks (2.0L)

  1. Ensure exhaust system has no leaks. Connect CO tester, using Adapter (VAG 1363/3), on CO tap tube. DO NOT remove oxygen sensor. Start engine and allow it to idle at closed throttle position.
  2. Spray air intake system with Leak Detector Spray (G 001 800 A1). Air intake leaks will draw in leak detector spray. The spray reduces air/fuel mixture ignition and engine RPM, and decreases CO reading. Repair leaks as necessary.
