Removing and installing parking aid control unit J446, right-hand drive vehicle — VW

🧭 Before you start

Ignition off and key out, then the driver-side fuse holder is removed with its wires still connected, followed by the bracket for the convenience system central control unit J393. The control unit bracket is unscrewed at its 3 securing bolts and lowered carefully on the connected wiring, the 3 connectors are released, and the securing bolt is undone to free the parking aid control unit J446 from the bracket. When installing, J446 is first pushed into its mounting on the bracket and then its bolt is tightened to 1.5 Nm; everything else goes back in reverse.

Fits: VW Touareg II (7P, 2010–2018)

Don't miss

• The driver-side fuse holder must come out, but its wires can stay connected.
• Lower the control unit bracket only as far as the connected wiring allows.
• Push J446 fully into its mounting on the bracket before tightening.
• Bolt securing J446 to the bracket: 1.5 Nm. Do not go by feel on a plastic bracket.
