Correct, a 2004 (Mk4) Jetta is not a CAN bus car. The error message about "K1 OK, K2 OK, CAN Not Ready" is correct and normal. When doing the autoscan he cannot do the "auto detect" because that only works on CAN bus (2005.5+) Jettas. He has to open the drop down box and choose his car/engine (a Jetta with an ALH engine) before he starts the autoscan. If this is what he did, I'm not sure what is wrong. One thing to try would be to try accessing individual controllers one at a time instead of an autoscan. You might learn something.

Have Fun!

2009 Jetta SportWagen TDI (gone but not forgotten)
2018 VW Tiguan SE (I wish it was a TDI)
