    VAG-COM/VCDS issues

    Guest-only advertisement. Register or Log In now!
    So, I connected my Ross-Tech VCDS to the car for the first time today. Partly to get a “baseline” and partly to poke around a bit.

    First issue, it had tons of “errors.” I have to dig through them, but many are things indicating my fuel pump is bad (of course I don’t have a fuel pump), my O2 sensors are bad (I don’t have those either) and other similar issues. Given that the car only has 700 miles on it, I am sure this is an issue of VCDS is not up to date with the current technology.

    Second issue, the bigger issue. After running the system check above, I thought I would poke around at some of the places on other platforms where we find nice features. The issue is that even though above I was able to to “scan” those modules for errors, all the modules I tried to directly connect to came up with connection errors. Basically, VCDS could not connect to any module on the car.


    Has anyone successfully been able to use the Ross-Tech Vag Com tool to do any tweaks on any e-tron?

    I'm not sure about the e-tron but the modules on the gas powered 24 models are pretty well locked down. I can't to even simple things like turn off the seat belt alarm or turn down the volume of the structure borne sound. Kinda frustrating.
    You might try going to the Ross-Tech forum and see if Uwe has any answers.

    I’ll check there. I did just get a VAS dongle so I can do the European headlight functions so maybe I’ll get ODIS and see what I can do.

    You need HEX-NET version of the VCDS tool. In addition, make sure you have update the dongle to the latest firmware!

    Ross-Tech has released a Beta version (only works with HEX-NET & HEX-V2 interfaces) of the VCDS S/W to interrogate 2024+ Audi/VWs w/SFD2, which you'll need to download:

    Although I have a '23 RS5 Coupe w/o SFD2, I'm currently using Beta 24.11.0 version S/W w/o any issues (so far).
