im not too certain about that. i know my vag com is current as of today, and i have still run into not being able to scan cars w/ aftermarket cd players. granted, the cars in question are older cars b/c the newer cars come loaded w/ ice that no one ****s w/ aftermarket radios anymore.
it is funny that i can scan the complete 2008-2009 audi line, but not a 98 jetta w/ an aftermarket radio…
here is a quick observation-- vag com does not have an autoscan option for the new rs4, and trying to go in as a a4/s4 will not work. so you have to go through the car manually. point being–vag com is an awesome tool, but it has flaws too. for what it is, i like it alot. better than the bosch hammer i use for porsches, or the vedis setup i use for any other obd2 car besides vw/audi/bently. i use this stuff on a daily basis, and the vag com is hands down one of my most valuable tools.
did you check my wastegate sugestion yet? or no time to?
