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.
