Thanks for choosing Just Answer . I'm Wolfgang here to help!!
I am confident we can resolve your problem together. Please understand that I don't know your skill level. In most cases when you have a problem with the way the vehicle performs, specialized tooling is required to acquire computer data/information or engine testing results. We didn’t build these complicated vehicles; we just diagnose and fix them. Also understand that I can't see, smell, hear, or touch the
vehicle either, so it may take a few replies to get to satisfactory results.
Note there may be an issue where the complexity of the issue will require a Premium Service. This service will be an addition to the normal question cost. Usually it does not come down to this but keep in mind!!
I am also going to direct you with the fastest, easiest and most common things to check first. Please be patient and permit me to do what I do best.
I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.
Below is my first answer or request for more information. If you do not understand it, or you need more information from me, or need me to go in more detail.
I do understand that it looks like a scan test was performed but was the transmission control module scanned for codes? that scanning cannot be done with a generic scan tool. Vag com scan tool or a professional scan tool is needed to get the codes from that module.
please let me know if a scan test was performed and what codes you know is stored?
