Diagnosis/Troubleshooting

Perform system test for small lift

NOTE: The test is carried out with the engine running at a standstill

1 - Select system test.
2 - Select "Request small lift".
If "Valve lift diagnosis not ready" appears, a fault may have been stored. In this case, delete the fault memory.

The engine must be at operating temperature.
1. Increase the engine speed to 2 000 1/min and hold for 30 seconds.
2. Then press the F8 key.
3. Increase the engine speed to 3 000 1/min and hold for 30 seconds.

After 3,000 ignitions the Tester indicates whether a fault is present or not.

In order to ensure that the fault is repaired, the flat-base tappets of the inlet valves of the entire cylinder bank should be replaced if a fault occurs.
