I think it was the BD highline steeringcontroller which sometimes worked and didnt work.
1K0-953-549-BD Type 2 SW 0070 Highline Yes 1.3 #1, #2
Notes:
#1: Depending on the hardware version of this module, it MAY or MAY NOT allow Cruise Control Retrofitting, so replacing the Steering Wheel Control Module may be required.
