Appreciate some help checking these tow bar electrics coding requirements before I commit!

Hi

Re: a Superb mk 3 2023 SE-L , has ACC, side assist, park assist, electric tailgate, rear parking sensors, Matrix LED headlights

I've install an Oris tow bar bought from PF Jones and also one of their own make dedicated wiring kits for the above car. I've fitted the towbar.

When coding the electrics there seems to be several different opinions out there as to what needs doing.

Please can someone who is more knowledgeable than me take a glance at the coding below and tell me if this seems reasonable (or have I forgotten something or am doing something unnecessary)

Thanks you

Coding requirements for PF Jones dedicated kit on a Mk3 SE-L superb estate

Step 1: The Gateway Master Switch

Do this first. It unlocks communication to everything else.

19 - CAN Gateway →

 Go to Installation List → Find 69 - Trailer → Check the box to mark it Installed → Save.

Step 2: The Core Drivetrain & Brake Alignment

01 - Engine Electronics:

Go to Long Coding → Byte 5 → Enable Bit 4 (Trailer Control Module Installed).

(Note: If the ECU locks this byte, the Gateway step above auto-configures it; do not force it if it rejects).

03 - Brake Electronics (ABS):

Go to Adaptations → Search channel: IDE04774 - Vehicle and Trailer Stabilization → Change value to Activated.

(Crucial for the anti-snaking trailer safety program).

Step 3: Adaptive Cruise Control & Windscreen Camera

Because the SE-L uses the high-definition windscreen camera and front bumper radar together for semi-autonomous features, you must code both.

13 - Adaptive Cruise Control (ACC Radar):

Go to Long Coding:

Byte 2, Bit 3 → Enable (Trailer Recognition Control Module Installed).

Byte 3, Bit 3 → Enable (Control Module for Towing Sensor / AAG Installed).

(Failing to activate Byte 3 is the direct cause of the often found "Front Assist Unavailable" error)

A5 - Front/Advanced Driver Assist (Windscreen Camera):

Go to Long Coding → Byte 16, Bit 1 → Enable (Trailer Recognition Control Module Installed).

Step 4: Infotainment & Central Electrics

This prevents a "Missing Databus Message" error across your central display.

5F - Information Electronics:

Go to Adaptations → Search Trailer or Trailer_Menu → Change Configuration_line_trailer to Activated.

09 - Central Electrics (BCM):

Go to Long Coding → Byte 1, Bit 1 → Enable (Trailer Hitch Control Module Installed).

Step 5: High-Spec SE-L Trim Level Requirements (Do Not Skip)

Because the SE-L car is heavily optioned, you must configure every single one of these modules:

D7 - Light Control Right 2 (Matrix LED Headlights):

Go to Long Coding → Byte 5, Bit 4 → Enable (Trailer Mode/Recognition Installed).

(This instructs the matrix beam to dynamically masks its light cells so it doesn't cause reflective glare off the trailer's front panel back into your rearview mirror).

6D - Electronic Tailgate:

Go to Long Coding → Byte 1, Bit 7 → Enable (Trailer Control Module/Recognition Installed).

(This disables the virtual foot-wave pedal plus remote opening and restricts the boot button from power-opening if it senses a trailer plugin, stopping a collision with anything that might be in the way).

3C - Side Assist / Lane Change Assist:

Go to Long Coding → Byte 2 → Set Bits 4–7 to 20 Trailer Recognition Control Module Installed.

(This digitally extends the side radar range backwards to account for the physical length of your trailer).

10 / 76 - Park Assist (PDC):

Go to Long Coding → Byte 3 → Set Bits 0–1 to 02 Trailer Hitch Installed.

(Automatically silences the rear reversing alarm when plugged in).

Step 6: Initializing the PF Jones Module Itself

The actual module included in your PF Jones dedicated kit must have its power management toggled so it doesn't drain your battery while parked:

69 - Trailer Function:

Go to Long Coding → Byte 4 → Set Bits 0–7 to 02 Terminal 30 Output switched (Pin 10) active while Trailer connected.

Post-Installation Reality Check

The moment you reconnect the battery after pinning the PF Jones kit, the car's network will panic because it lost power. Follow this process exactly to clear it:

1.       Save all your coding changes.

2.       Run a Global DTC Clear / Clear All Faults via your tool.

3.       Turn the ignition completely off, lock the car, and walk away for 5 minutes to let the CAN-bus sleep.

4.       Turn the car back on, ignore any lingering yellow wheel or dash symbols, and drive it down the street for 100 yards. The ABS rings and ACC radar will read the rotating wheels and self-calibrate, turning off all remaining dash warnings.
