ODB feedback connection

Recommended Posts

It is possible, but much more complicated than other brands like Kia, Hyundai etc. That is because VW use a CAN-gateway so you cant easily sniff the CAN buss.

To do that you need to hardwire an OBDII connection to the inside of the CAN-gateway.

 

Or if possible to get the original documentation that explains what PID to ask for information.

It should be fairly easy to get data on en e-Golf. These are the routes I know of:

1. OBD - You have to request the information you want from the gateway. The necessary codes are known and mostly shared with the e-Up/Mii/Citigo. In the going electric wiki and the linked github you should find everything you want: https://www.goingelectric.de/wiki/Liste-der-OBD2-Codes/
I'm using carscanner with the e-Up 2020 codes and most stuff works on my 2020 e-Golf.

2. CARNET/WE Connect - You can get most relevant data like SOC and range estimate. Even avg. consumption from the last trip. To get it, use https://github.com/robinostlund/volkswagencarnet

3. Android Auto - Through the Android Auto exlap channel, you can read at least some stuff like the SOC. No additional Adapter or service required. This program displays it as fuel content, but it matches the SOC https://github.com/jilleb/mqb-pm

4. CAN - Since I'm running Openpilot, I have constant access to the unfiltered can data. So I just have to find the relevant message.

 

We could even combine the data to have remote access and some real time data when in the car.

How would I integrate the data into ABRP? I have found the Token in the App, but haven't found anything else.

For the moment, i use car scanner (ODB2 dongle) in parallel (Android) with ABRP. So, I can easily compare the ABRP prevision with the real SOC displayed by car scanner. However, it's neither nice nor ergonomic ... Half of the screen is used to merely display SOC (car scanner) while only the other half remains for navigation ... Having both in the same application would greatly enhance the user experience !

For now you can user EVNotify and select ID3. The SOC works on e-Golf as well. Haven't tested the ABRP integration yet since my OBD port is already occupied right now, but it should work.

Hello Vrabetz,

Unfortunately, EVNotify does not support the Mii Electric (same as VW e-up 2nd generation). I have tried EVNotify while setting the car as being an ID3. Of course, it does connect to ODB2 but, sadly,  the PID's seem to be different ! Aaarghhh !

The PID for e-up are here:

Just ask EVNotify to add support for it and he will help you as he do with my work for the ID.3

Best regards

The PID used by EVNotify for the ID3 is in the e-up wiki and works with e-golf. So in theory it should work. Perhaps some issue with the bluetooth adapter or something like that. For me it also only seems to work when the ignition is on right now. And only SOC is supported so far (will change shortly).

I own a 2019 e-Golf SEL Premium and have just installed the Vgate vLinker MC+ Bluetooth OBD dongle. On the first attempt, ABRP found the dongle, and live data is enabled with my iPhone and CarPlay.
