you would have to get a new ecu as well as far as i know but if you want it done get it done by someone that knows or a tuning place..last time i was at the dealer the person that was getting parts needed an ecu and the guy asked 5 or 6 speed and he said 6 and the guy was like well thats going to be 1800
Talked to my local idiot (I mean VW dealer tech). He told me that there is no way at all this can be done. But this guy also told me that there is no way that I could change out the cam on my car. So who knows. Sure would be nice to have a 6 speed with my SC.
