Today we going to struggle with this VW Touareg . The complain is malfunction in the Parking Assist / Aid . We didn't get any fault / error codes in the system , doesn't matter we had two unplugged sensors , but after poking around I manage to find the solution to this .
Fault codes :

01628 Sensor for Parking-Aid , Front Mid-Left ( G254 )
01627 Sensor for Parking-Aid , Front Mid-Right ( G253 )
00435 Front Right Inner Parking Aid Sensor ( G333 )
