Mokka — Workshop Notes
Turbo petrol drivability, intake leaks and sensor plausibility under load.
What owners typically report
- Intermittent engine light with “runs fine” days between.
- Hesitation under load, especially in higher gears.
- Short-trip usage causing repeat emissions-related faults.
- Rough idle / misfire that disappears when warm.
Fast, high-signal checks (before you buy parts)
Fuel trims first
LTFT/STFT tells you whether to chase air leaks/MAF (lean) or fuel control (rich/negative trim).
Misfire logic
If the misfire count climbs only under load, treat it as boost/airflow/fuel delivery before ignition.
Temperature matters
Thermostat and ECT plausibility can quietly cause repeat emissions faults by blocking closed-loop/regen conditions.

Use the AI mechanic assistant with your exact model year, engine, mileage and symptoms — it works best when you include freeze-frame data and what you’ve already replaced.
