Interference Suppression
WARNING: This page is about a different car, the 2015 Volkswagen Passat, 2014 Volkswagen Passat, 2013 Volkswagen Passat, and 2012 Volkswagen Passat. However, it is still accessible from the selected car via links, so may be relevant.
Interference Suppression Measures
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 ground cables previously used for interference suppression purposes are no longer used because this is now done very close to the source of the interference.
