Disadvantages of the VW BAD engine
- A very complex intake system with a lot of sensors constantly fails.
- The motor not only breaks down regularly, but also requires highly qualified service.
- Intake valves, throttle valve and EGR valve are quickly overgrown with soot.
- Even before 100,000 km, ignition coils or a phase regulator often fail.
- Oil burning due to the occurrence of rings usually begins to run 100 – 120 thousand km.
