Front Radar Sensors
There are two different types of front radar sensors, the Mid-
Range Radar and the Long-Range Radar sensors.
Mid-Range Radar (MRR) Sensor
The MRR Distance Regulation Control Module J428 is
located at the front center of the vehicle, either behind the
VW emblem, or below the VW emblem in the center of the
bumper cover.
This is a radar sensor that detects vehicles and obstructions
in front of the vehicle. It is used differently for different
systems. It has the following features:
• It has a frequency of 77 GHz
• To keep ice off at lower temperatures, the MRR has a
heater
• Range:
Up to 525 ft (160 m)
• Speed: 0 - 100 mph (0 - 160 km/h)
