i still cant seem to get mine to work with the 409 version
I couldn't get it to work properly either, personally i'd uninstall 409 and install 311.2 which is the version i'm now using, with my Alpha-bid USB cable.
You will also need Windows XP home should do it, cos i couldn't get win2000 pro to accept the FTDI USB drivers. from here

To summerize what i found to work
Windows XP (home)
Alpha-bid USB cable (£3.99) + P&P
Ross-tech 311.2 software version (free)
FTDI USB drivers listed above (free) top one not the alternate driver.
you'll more than likely need to go into device manager and change the com3 port settings BAWD rate from 9600 to 4800. cos I couldn't get it work at 9600
You'll also need to buy a license from Ross-Tech at $99 (£50) to get any access to your car, cos the free software won't allow you to change any settings..
I must admitt it was a right pain in the butt, trying to get it all working properly, but now i have.... was it all worth it... probably cos it allows "you" to do it and not have to pay someone else, but once you have done what you want, it's done isn't it.......
And my local SEAT garage quoted £40 & F1 in Brighton quoted £30, all in all it all cost me £62, if you don't add the time and replacing broken bits on my laptop...
which cost me a further £60 odd squids...
