Possible causes
- Injector behaviour drifts at low temperature high
- Poor fuel atomization at cold start medium
Inspection / repair
- Difficulty: medium
- DIY: shop recommended
- Estimated cost: 200–1500 €
- Estimated time: 1–6 h
- Component: fuel injector cyl 7
- Component: cold start calibration
- MIL / check engine light
- emissions-relevant
- drive cycle required
