The controllable coolant pump may have a leak between the coolant and vacuum circuit via negative pressure and allow coolant to enter it. If the electric switchover valves are exposed to coolant, a continuous increase in the component part temperature may occur and cause a fire.
In addition, the brake booster may become damaged over time and reduce brake performance which could lead to an accident.
