Disadvantages of the VW BLS engine
- These are quite reliable units and problems happen only at high mileage.
- Due to the fastening with one bolt, the unit injectors lose their tightness over time.
- The culprit for thrust failures is most often a jammed turbine geometry.
- Another cause of unstable engine operation is often a clogged particulate filter.
- Saving on oil leads to wear of the camshaft cams and hydraulic lifters.
