Please check the compatibility of the currently installed comfort control unit (= control unit address 46). Experience has shown that in around 30% of all cases this control unit must also be replaced with a Highline control unit due to equipment requirements.

Part numbers of capable control units which are NOT to be replaced e.g.: 8W0907064CD, 8W1907064BH, 8W1907064AP, 8W0907063CG, 8W1907064AH, 8W1907064BP, 8W0907064AH, 8W0907064FH, 8W0907064GH, 8W0907064CH

Part numbers of NON-capable control units which need to be replaced e.g.: 8W0907064B,8W0907064BB,8W0907064EA

You are welcome to write to us about this, along with the currently installed part number read out using a diagnostic system (VCDS, ODIS, KECODI, etc.). We will check this for you if the part number installed on your vehicle is not listed here.

If a replacement of the comfort control unit is necessary, we can offer this to you under article number: 10780.

Installation information:

The external door handles are not changed (these always fit) but the original sensors are installed inside the existing door handles; currently only "blind caps" are installed there.

In addition to the two Keyless Go antennas already installed (1x in the center console and 1x in the trunk), a total of 4 antennas are now installed in the vehicle; these two missing antennas for upgrading from KeylessGo to KeylessGo+Entry are located in the doors.

INFO: Antennas are already installed because of the standard function of starting the engine via start button (= Keyless Go).

The existing vehicle keys are already functional and do NOT need to be replaced.

The cable sets run from the comfort control unit (= BCM2, this is located at the rear left in the trunk) to each door.
