Make sure that there are no leaks from the various test equipment connectors.
- Disconnect fuse F21 (15 A), located in the additional junction unit in the engine compartment.- Temporarily connect the battery poles.- Select "DIESEL CYLINDER COMPRESSION" on the Examiner in the instrument ambient.- Fully depress the clutch pedal on versions with a manual gearbox or the brake pedal on versions with automatic transmission and turn the engine over using the starter motor until the compression value appears on the Examiner.
To measure the compression pressure, start the engine using a fully charged battery.
- Repeat the test for the remaining cylinders.- Check that there is not a great difference between the pressure readings for the cylinders.
