after 9 months of successfully using nefmoto and vagcom, my car out of nowhere wont respond to either.  vagcom stalls and nefmoto - after trying - says ftdi echo test failed.

the last time i flashed, everything worked fine.  i've been driving the car for two weeks since that.  no problems at all to my knowledge.

this afternoon, i hardwired a v1 and jostled with the fuses.  is it possible i messed up one of the fuses?  everything seems to be operating fine in the car but just simply cant connect to any of the computers.  

this is actually a massive problem if i cant resolve it, because my cars tune is half finished... please help!
