Disadvantages of the VW AGN engine

- Often only the vacuum regulator of the intake manifold flaps fails.
- Dirty injectors or throttle causes floating engine speed.
- A lot of problems for the owners are thrown by the capricious ventilation system of the quarry.
- A rather modest resource here has a lambda probe, as well as a coolant temperature sensor and a mass air flow sensor.
