Disadvantages of the VW BWS engine
- This is a very reliable unit with a high resource, but its fuel consumption is too high.
- In winter, it may not start well due to freezing of condensate in the exhaust system.
- Like all direct injection engines, it suffers from carbon deposits on the intake valves.
- Sometimes there is a sharp increase in pressure and leakage of the injection pump due to regulator failure.
- The weak points of this motor also include the membrane of the crankcase ventilation system.
