Hi all. I wanted to share a guide around coding the bike rack tow bar electronics as I personally struggled a bit being a first timer at this.
These instructions at least apply to the 13-pin Jaeger harness that is required to code into the system. I assume that exactly the same steps are taken when working with ID3. ID4, ID5 and Enyaq follow a similar path, but additional control units might be required for activation. My Born does not have lane change assist, driving assist or other "higher-end" assistance functions from the factory, so it could be that better equipped vehicles require additional control units for activation.
- Open OBDeleven, navigate to Control Units
- Click on the big green dot at the bottom right to add control devices
- Find "69 trailer function" and activate it
- Navigate to 09: Central electrical control. You do not need to enter a security key, even though some instructions say so. Navigate to Customization -> Networking -> Trailer coupling -> Activate
- Navigate back to the control unit menu to 6C: Rear view camera system. Go to Long coding -> Equipment_ahk -> installed
- Navigate back to the control unit menu to 76: PDC control unit. Go to Long Coding -> Trailer -> Manually detachable tow bar
- Navigate back to the control unit menu to 13: Adaptive Cruise Control. Go to Long Coding -> Trailer Sensor Control Module -> Installed
- Navigate back to the control unit menu to A5: Front sensors. Go to Long Coding -> AAG -> Coded
Remember to save all codings and your trailer with its electronics should now work.
The kit manufacturers' instructions also recommend enabling the features under the controllers. If you have a Born with all the available accessories, I suggest you browse the controller list for those additional devices as well and enable the trailer options under them.
- 46: Central module comfort system - Long coding -> Trailer monitoring -> Set up active trailer control unit -> Installed
- 3C: Lane change assistant - Long coding -> Control unit for drawbar -> with control unit for drawbar
- 17: Dashboard insert - Long coding -> Trailer -> Yes
- 74: Chassis control system - Long coding -> Trailer -> Yes
- 6D: Tailgate electronics control unit - Long coding -> Trailer -> Installed
Please excuse any spelling mistakes in the instructions as I am not a native speaker and this is a translation from English. I thought it might be of interest to the German readers of this forum. Please let me know if you need help fitting a tow bar. I can give you some advice.
