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?
