P02CC Cylinder 1 Fuel Injector A Offset Learning At Min Limit
The PCM applies a per-cylinder injector offset (Mengenausgleich) to compensate for production-tolerance differences in injector flow rate. On cylinder 1 the learned correction has reached its minimum value — the injector is delivering significantly more fuel than the calibrated reference and the controller cannot trim it any further.
Is it safe to drive with P02CC?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
Common causes
- Most likelyInjector over-delivering — worn nozzle or stuck-open seat
- PossibleCalibration code not programmed after replacement
Symptoms
- Check engine light on
- Misfire or rough idle on the affected cylinder
- Increased fuel consumption
- Possible fuel smell or smoke from exhaust
