Based upon the above links and your research; you have narrowed down the possibilities. Now it just depends on how you approach the repair process you can progressively replace parts and test after each part is changed and hopefully, through a process of elimination, you will find the problem. What kind of scan tool; do you have access to? For testing each component with output tests, live data and possibly doing the coding of a new or used ecu, you really need VCDS from Ross Tech. When it comes to the ecu coding; you could have someone repair your original ecu or transfer the coding to another ecu; thus, eliminate the need for VCDS, to do the coding. I would contact Ian at reflect tuning.com and see what your repair options are. I don't know; what coding options, normal auto parts stores would have with this type of thing (if you purchased a new ecu through someone like autozone). When it comes to coding issues there are two routes; it seems to go all the way, get VCDS, Vag Tacho for pulling the secret key code or ship out the repair and/or coding to a specialized repair shop like reflect tuning, thus plug and play, repair complete. A third option; is take it to a Volkswagen dealer and spend tons of dough for them to do everything. My personal approach; would be to replace the parts progressively and test, confirm things as you go along, until you find the problem. Keep in mind I have access to VCDS, vagtacho, the secret key code and everything needed to complete the repair. Think about your resources; how far you want to go with doing the ecu coding/repairs yourself, how much money you want to spend and how quickly, you want the repairs completed.... then, we will go from there.
