Disadvantages of the Mini W17D14 engine
- The main problems of the engine are associated with fuel-demanding piezo injectors.
- In second place here is the lubricant consumption due to the occurrence of oil scraper rings.
- Also, often oil oozes through all the seals due to clogged crankcase ventilation.
- Periodically there are leaks from the injection pump and failures of the fuel pressure regulator.
- Still here they often burrow and break off when unscrewing the glow plugs.
