Interference Suppression Measures
WARNING: This page is about a different car, the 2010 Volkswagen Passat, 2009 Volkswagen Passat, 2008 Volkswagen Passat, 2007 Volkswagen Passat, and 2006 Volkswagen Passat. However, it is still accessible from the selected car via links, so may be relevant.
All standard and optional electrical consumers in the vehicle are shielded.
This includes all sensors, actuators and all electrical motors in the vehicle, as well as controllers in control modules that could cause high-frequency interference.
To suppress interference, all electrical parts such as, condensers, coils, and diodes are integrated with the electrical components.
Interference suppression components are also built into the connection housings of electrical consumers.
The grounding cables that used to be employed for shielding purposes are no longer used because interference suppression is now done as near as possible to the source of the interference.
