Cylinder 8 Fuel Injector A Offset Learning At Min Limit
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The PCM applies a per-cylinder injector offset (Mengenausgleich) to compensate for production-tolerance differences in injector flow rate. On cylinder 8 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.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
- Safe to drive
- Usually safe to drive short distances, but the fault will not clear itself and can worsen or fail an emissions test.
- Urgency
- Diagnose soon
- Will it pass emissions
- No
- Check engine light
- Solid
- Misfire or rough idle on the affected cylinder
- Increased fuel consumption
- Possible fuel smell or smoke from exhaust
Many vehicles show no symptom at all beyond the warning light. The absence of a symptom does not mean the fault is not real.

Ordering reflects how often each cause is responsible in general, not a probability for your vehicle. Confirm by testing.
