Cylinder equalization above lambda, cylinder 1: cylinder-
selective oxygen-sensor control, upper limit reached

Fault description
The diagnostic function monitors the lambda at the
individual cylinders.

Condition for fault identification
Test condition:
The fault is recognized when the mixture for one cylinder
must be corrected by more than +/- 15 %.
Potential problem source(s):
- Defective injector
- Oxygen sensor defective
- Fuel pressure fluctuates or is consistently too high or too
low
- Defective wastegate control
- Exhaust backpressure too high
Terminal condition: none
Voltage condition:
- None
Temperature condition:
- from - 10 °C to normal operating temperature
Time condition:
- None
Other conditions:
- v > 90 km/h

it remains present for longer than 60 sec.

Action in service
- If diagnostic fault codes related to the oxygen sensor,
catalytic converter or fuel system are present, repair these
- Check fuel pressure
- Check wastegate control
