My VCDS should be here tomorrow from ross-tech, and I plan to use it first to diagnose some shifting issues that I am having in my MK4 Jetta GLS 09A. (No shift to second / third unless using super light throttle.)
I've looked at the Wiki, and searched around, but I didn't find much in the way of guidance in terms of diagnostic procedures for the 09A in VCDS.
Research into the symptoms leads me to believe that there is a good chance this is a solenoid issue.
Does anyone have any tips or resources to provide as I dive into VCDS to investigate prior to purchasing a solenoid kit from cobratransmissions? Ideally I would like some additional verification that the issues that I am having are solenoid / valve body related, rather than mechanical, such as bands or friction plates.
