- Engine / equipment
- OM607 and OM608 1.5 diesel of Renault origin (K9K): A 160/180 CDI and d, B 160/180, CLA 180 CDI and d, GLA 180 d, Citan
- Period mentioned
- 2012–2026
- Symptoms
- Smoke, hesitation or hard starting (injectors); unstable idle, power loss and engine light (EGR); particulate filter warning in town use; oil consumption.
- Possible cause described
- It is Renault's 1.5 dCi with Mercedes electronics. On the OM607 the injectors are the main weak point; the OM608 that replaced it in 2018 has fewer problems. The EGR builds up carbon, mostly between 60,000 and 100,000 km, and the particulate filter clogs on short trips.
- Check for the garage
- Identify the engine (OM607 until 2018, OM608 after), measure injector balance rates, check the EGR and particulate filter status and watch the oil level.
- Cost cited in the source
- Depends on the part (injectors, EGR or turbo); the sources consulted give no reliable figuresA rough figure from the original database, not an up-to-date quote.
Mileage cited in the database: 60,000–100,000 km. This is not a maintenance interval and does not predict a failure.
