- Misfire or rough idle on the affected cylinder
- Increased fuel consumption
- Possible fuel smell or smoke from exhaust
Inspection / repair
- Difficulty: hard
- DIY: shop recommended
- Estimated cost: 150–1500 €
- Estimated time: 1–4 h
- Component: alternative fuel injector
- MIL / check engine light
- emissions-relevant
