Hi everyone! First let me say thank you to gmenounos for putting in the work for such a useful tool! I have tried to use it to retrieve the SKC for my 04 Touareg but it's not coming through and I *think* I know why. 04 Touareg isn't on the list of cars that use CAN for diagnostics, but I believe it uses kw2027 instead of kw1281. Also, it took me a bit to figure out the ignition had to be in the on (koeo) position for it to communicate. Am I correct in thinking the cluster uses an incompatible protocol? Here is what the test said (I've shortened it up a bit though from ALL of my attempts). For all the search ninjas that might be reading this post looking for answers, I am trying to replace a faulty electronic steering lock (esl) actuator instead of replacing the entire steering column for a steering workshop fault.
