1 - Select System test.
2 - Select 'Request small lift'.
If "Valve lift diagnosis not ready" appears, a fault may have been stored.
1. Erase the fault memory.
3 - Activate the system test with the F8 key immediately before acceleration with wide-open throttle.
The message "Drive link active" then appears.
NOTE: If 'Request small lift' appears, the valves remain at small lift, i,e, the performance is reduced dramatically.
4 - Perform acceleration with wide-open throttle in 2nd gear, until "Valve lift diagnosis completed" (max. 4000 rpm) appears.
At speeds above 4000 rpm, misfires may be stored. Erase the fault memory and repeat the test.
NOTE:
- If a fault is detected, it is only recorded in the fault memory after 6,000 ignitions (at idling speed approx. 3 minutes waiting time).
- It is important to observe the oxygen sensors during acceleration with wide-open throttle or to record their behaviour with the data logger.
Diagnosis/troubleshooting
NOTE: Do not use contact spray on the oxygen sensor plug connections as this may cause irreparable damage to the wiring (contamination of the
oxygen sensor via the reference air channel).
Diagnosis/troubleshooting - all naturally-aspirated models
NOTE: The DTC only covers electrical faults here.
Diagnostic conditions
- Battery positive voltage between 10 V and 16 V
- Exhaust temperature less than 800 锟斤拷C
- Oxygen sensor heating switched on for at least 120 seconds
NOTE: DTC P0132 is stored by the DME control module when the sensor voltage is continuously above 1.5 V for more than 5 seconds
