Hi,
I recently got a ID.4 1st. I'm lacking travel assist. Does anyone know if it will be possible to add travel assist as a software upgrade in the future?
Many things are possible to be altered in software in this very software dependent vehicle, provided the hardware is in place to accommodate same. In the case of travel assist there are various active/passive components required, so it does depend to a degree on your model and how it is optioned, with various options differing by global region.
Possibilities vs. how VW will proceed only VW knows.
Travel assist is combination of few assists in one (ACC, lane keep assist, lane guidance assist, and traffic jam assist).
In older VW, this is very doable and relatively easy by using a tool like VCP. However, VW brought SFD protection and it is not easy to bypass this. (Though there are websites you can get SFD token and mod your car).
In ID.4, here is the list of modules currently protected and not protected by SFD:
list of the modules protected by SFD
01-Engine
03-ABS Brakes
09-Cent. Elect.
15-Airbags
17-Instruments
19-CAN Gateway
23-Brake Booster
5F-Information Electr.
75-Telematics
8123-App server 1 system 1 adaptive
8124-App server 1 system 2 Java
8125-App server 3 system 1 infotaint.
C002: SW Cluster Embedded (SWC2)
C003: SW Cluster Housekeeping (SWC3)
A5-Frt Sens. Drv. Assist is the module that is mostly related to travel assist, but if I remember correctly central electronics and information electronics modules need to be also updated. Considering latter two are protected by SFD, you might have a hard time getting Travel Assist.
However, I think VW group is excited about OTA system because now they can charge people for additional features that enthusiast diagnostic tool companies were providing for a while. It is very likely that in the near future you will have a store in the car menu or your phone app to purchase features like Travel Assist.
Note: I previously had an e-Golf before and I activated travel assist on the car, and it was a fun to drive, especially on the highway.
From what i understand, Travel assist needs side assist, and in Europe, the cars that don't have travel assist, also don't have side assist (hardware).
All US models include Travel Assist. Travel Assist is not included on all models in other countries. The original poster is not in the US.
