Exhaust System: Service and Repair

Leak Test For Exhaust System

Leak test

NOTE: Permitted test pressure is 1.4 bar.

1. Remove tailpipes.
2. Fit plugs -1 - into exhaust tailpipes on the rear silencer -see Figure-. Insert plugs into tailpipe outlets. To adapt the diameter (seating surface of rubber seal), turn each lever clockwise or anti-clockwise until the tailpipe outlets are air-tight by moving the tensioning lever through 90 degrees.







3. Connect a pressure gauge -2- to a valve and subject exhaust system to max. 1.4 bar of excess pressure.







Recommended aids for leak testing:







4. Spray individual connection points on the exhaust system (e.g. manifold flange, clamping sleeves) with test spray to make any leaks visible. Repeat test procedure if necessary.
5. Pull off pressure gauge and remove both plugs.
6. Install tailpipes.
